斯坦福大學醫學院有位教授,把一批自稱遭遇過 UFO 的人的腦部核磁共振一張張看完。他原本是被請去評估這些人腦部損傷的。

看到最後,他在基底節正中央發現了一塊異常明亮的區域。一開始他以為那是損傷。後來發現幾乎每個人都有,訊號特徵還顯示那是活組織,位置正好是尾狀核頭部和殼核。他不放心,又去公開資料庫裡調了約兩百例隨機腦影像做對照,一例都沒找到同樣的特徵。

這個人叫加里·諾蘭(Garry Nolan),斯坦福醫學院教授,一輩子研究單細胞層面的人類生物學。他在 Lex Fridman 播客第 262 期裡,用了兩個多小時,把這條從細胞一路延伸到 UFO 的線索講完了。

先從一個荒唐的問題開始

訪談開場,主持人丟擲的問題很哲學:如果讓你作為更高階的智慧,向一個更低階的智慧展示自己,你會怎麼做?

諾蘭的回答沒有直接落到外星人身上,他先講細胞。他說細胞裡那些由蛋白質搭建的微型機械和奈米機械,是生物學裡最讓他著迷的部分。每一個細胞內部都有一臺不停處理環境資訊的動態計算機,而核心是 DNA。

大多數人把 DNA 理解成一串線性程式碼。諾蘭說,它是程式碼套程式碼套程式碼,真正在做複雜運算的,是表觀遺傳狀態。

如果你曾經想要相信上帝,就往細胞裡面看一眼。(加里·諾蘭)

這句話放在訪談的最前面,修辭成分很少。它決定了後面所有討論的底色:在諾蘭的世界觀裡,資訊、計算、生命是同一件事的不同側面。

DNA 不只是硬碟,它是一份對未來的預期

主持人問,DNA 既是資訊又是計算機,那這臺計算機是怎麼來的?

諾蘭把視角又往後拉了一層。他說你得先退到"宇宙是一臺計算機"這個位置上。所有被稱為粒子或者波的東西,在他看來更像一個計算過程,而生物學嵌在這個計算矩陣裡。蛋白質裡的每一個原子,都坐在這張計算網格上。

至於 DNA 從哪來,可以一路追到理查德·道金斯(Richard Dawkins)的自私基因假說。諾蘭的看法稍有不同:DNA 不是時間中的一個瞬間,它自帶對身體的預設,也自帶對它將要生活的環境的預設。

人類基因組只有三十億個鹼基對。諾蘭認為它承載的資訊量,超過當前全部技術體系的儲存資源總和。原因在於,你是誰,既包含你作為一顆卵子時的狀態,也包含你死亡那天的狀態,還包含你身體裡所有細胞型別和器官的構造方式。

它是一座關於資訊的計算水庫,也是一份"你將會成為什麼"的預期。(加里·諾蘭)

所以他反過來提了一個工程問題:如果你想造最好的儲存系統,可以去逆向拆解一個人。造出來的系統不會只有線性編碼,還會帶著"它可能變成什麼"的全部可能性。

這裡有個容易滑過去的點。主持人追問,那是不是意味著部分資訊存在身體之外?諾蘭說是,因為 DNA 自帶一份對環境的預期,那份預期的物件確實在體外。

細胞裡沒有眼睛,但它知道外面應該有光。這就是他說的"儲存在外部"。

把地球重跑一百萬次,會得到一百萬種答案

順著這個思路,主持人問了個思想實驗:如果把地球的歷史重跑一百萬次,會得到多少種不同版本的這種計算機?

諾蘭說每一次都會不同。前提是承認沒有宿命,沒有全預設,起始處存在某種隨機性。那他想象得到多少種生命形態,就有多少種。

他補了一句限制條件:除非宇宙的底層基質裡已經寫死了某些東西。比如蛋白質的左手性,如果沒有底層約束,未必每次都是左手。

但他也承認另一種可能:這套系統可能極擅長尋找高效解,而對這顆行星的環境,高效解的數量是有限的。

這就滑向了人擇原理那一套。多重宇宙裡可能存在著無數種規則不同的宇宙,我們只活在那個規則允許生命出現的宇宙裡。

於是主持人把問題推到最大:那外面有多少外星文明?

諾蘭的答案是"數不清"。他給的理由很樸素:那麼多空間只留給我們,太浪費了。

他講了一個童年畫面。七八歲時他翻《國家地理》,看到一張當時最新的宇宙影象,大概是 1968 或 1969 年。他盯著那張圖想,這片空間裡有多少帝國興起又覆滅,我們永遠不會知道,這件事讓他覺得難過。

從那以後他一直讀科幻。他偏愛那些建立在紮實科學和演化論之上的科幻作家。

拉里·尼文(Larry Niven)寫過一種叫"傀儡師"(Puppeteers)的文明。如果智慧從群居食草動物演化而來,領導位置可能在後不在前,遇到危險先把別人推上去,道德律令變成了怯懦。尼文圍繞這個前提寫了整本書。

大衛·布林(David Brin)的"提升"(Uplift)宇宙裡,不同演化背景的智慧各自長成不同形狀的文明。

諾蘭喜歡這種寫法,因為文明的假設會長成它出生環境的形狀。這也是他後來理解外星人行為的底層框架。

目擊故事真正讓人不安的地方,是它們長得太像

話題切到 UFO,主持人問他,聽過那麼多遭遇故事,最著迷的是什麼。

諾蘭說,是相似性,是這些故事的整齊程度。

他先做了一個宣告,這個宣告在整場訪談裡反覆出現:很多人以為他一旦推測就等於相信,事實並非如此。推測只是創造力,是假說的起點。他聽到的軼事,他自己並不必然相信。

但他還是願意聽,因為那至少是原始資料。同一個故事聽到第三遍第五遍,你就得承認裡面可能有點東西。

他也給了一個讓自己冷靜下來的解釋:也許人類心智和意識裡存在某種榮格意義上的底層結構,讓這類故事一遍遍從 DNA 裡、從那套預設裡長出來。榮格談過集體無意識,談的正是這一類現象。

在所有相似點裡,最讓他在意的是那條反覆出現的資訊:你們沒有照顧好自己的世界。

這條資訊出現的時間遠早於氣候變化成為公共議題,也遠早於今天關於汙染和環保的各種說法。

他舉的例子是辛巴威。上世紀九十年代中期,一所學校的午休時間,五六十個孩子,白人和黑人都有,家境和受教育程度都不錯,他們在操場上看到一個飛行器,還有幾個小人。孩子們跑進教學樓找老師,講的是同一個故事,畫的是同樣的圖。有幾個人接收到的資訊是:你們沒有照顧好自己的世界。

三十年後,當年那些孩子長大成人,有人拍了紀錄片,他們對著鏡頭說,那是真的發生在我們身上的。

諾蘭的態度是:這事發生了嗎?是幻覺,還是被某個東西植入的幻覺,還是物質層面真實存在的?他不知道。但他注意到一個細節,那些孩子當時七到十歲。七到十歲的孩子不會那樣串供。

不管它是真是假,我都覺得這是值得關注的資料。互不相識的個體講出同一個故事,這件事本身就值得進一步調查。(加里·諾蘭)

你會怎麼向螞蟻介紹自己

主持人把問題轉了個方向:如果從外星視角出發,你會怎麼和其他生命體溝通?

諾蘭的切入點很工程:要理解一個系統,你得去擾動它。就像戳一下看看它會不會起反應。擾動之後,如果擔心它,還可以順勢把它往某個方向引導。

他把人類歷史鋪開來看。前文明時期,你出現在森林裡,就表現為森林裡的精靈,資訊透過精靈傳遞。人類稍微文明一點,你就表現為神,你就是神。到了今天,不是所有人都還信神了。

那我們信什麼?我們信技術。那你就以技術的形式現身。

但所有版本里都有一條共同線索:你不孤單,這裡有別的東西和你在一起,有東西在看著你。(加里·諾蘭)

至於為什麼只給一點點資訊,諾蘭用了一個 parenting 的類比。好的父母不會把一切都告訴孩子,學習需要犯錯,什麼都告訴了,孩子就懶了。

主持人在旁邊補了一句:所以我們是一群憤怒的猴子,而它們可能在盯著,不希望這群猴子在銀河系的旋臂上到處亂踩。

諾蘭沒反駁。他還加了一條:我們希望高等智慧願意照顧我們,就像我們願意照顧非洲國家公園裡的猩猩。但沒人想照顧蟑螂。這條線是人自己劃的。

基底節那處異常,最後指向了別的地方

訪談中段,諾蘭講了那段最容易被誤讀的研究。

起點是一批被送到他這裡的人,以及他們的核磁共振影像。有人懷疑這些人腦部受過損傷。結果大部分病例最後被判定為哈瓦那綜合徵(Havana syndrome)。諾蘭說,損傷這部分故事在他這裡基本結束了,那是別人的問題了。

但在看影像的過程中,他注意到基底節正中央有一塊區域,一開始以為是損傷,後來發現所有人都有。再細看其他讀數,那其實是活組織,是尾狀核頭部和殼核。

他當時問斯坦福一位做精神科的好友,基底節是幹什麼的。對方說,管運動和神經控制。諾蘭覺得奇怪,因為他同時讀到的論文指向另一件事:基底節參與更高層的智慧活動,位於執行功能下游,和直覺、規劃有關。

仔細想想也說得通。運動控制需要一個集中的地方,而運動控制離不開對環境的知識。你不想伸手打翻桌子,你走過一個房間時要知道會撞上什麼。所有這些規劃都需要呼叫感官、慾望、記憶,需要知道你身邊有哪些人想避開、哪些人想靠近、服務員手裡的盤子快要掉了。

這些計算全在基底節裡完成。它現在有個外號,叫"腦中腦",是一套目標處理系統,服務於執行功能。

我們發現的不是一種能讓人和 UFO 對話的東西。UFO 社群把這一步邁得太大了。我們發現的是一種更高功能的資訊處理形式。(加里·諾蘭)

接下來是他自己都覺得最有意思的部分。他們去看這些"指示病例"的家人,發現這種特徵在家族裡出現。他本人、他的兄弟、他的姐妹、他的母親,都有。

他們也見過夫妻雙方都具備這種特徵的組合,而且不止一對。諾蘭說,如果這種特徵在人群中的比例是百分之一到三百分之一,那麼兩對夫妻雙雙具備,在統計上意味著什麼?要麼是婚配範圍受限,要麼是同類相互吸引。

再往下的推論他做得很謹慎。他說,如果直覺的定義是"看見別人看不見的東西",這話裡沒有靈異意味,指的只是看見眼前某個別人會直接忽略的事物,那麼這種能力或許就是更高層智慧的一種表現:我能認出這個事物和我環境裡的常規不一樣,雖然我還不知道它是什麼。

主持人在這裡插了一段自我剖白,說自己似乎也能在很多瞬間看到某種魔力,對活著這件事有一種近乎化學性的興奮,像一直處在某種微醺狀態。諾蘭的回應是,人的大腦確實被基因和成長環境塑造成只能看見世界的某些切片,有些人天生對異常資訊更敏感。

然後他補了一句:這些人裡有很多最後也成了科學家。看到反覆出現的模式,然後某天冒出一個不對勁的東西,被這個不對勁吸引,順著線往下拉,看看核心是什麼。

一塊來自烏巴圖巴的鎂

諾蘭手上有一些被聲稱是 UFO 殘骸的材料。他強調是"被聲稱",政府沒提供過任何一件,全是收集者交來的,而且帶著相對合理的保管鏈。

這些材料幾乎都是金屬。要麼被說成是某物留下的熔融金屬,要麼被說成是從某個爆炸物裡掉出來的。

檢測手段主要是質譜,五六種不同的質譜各有用途,有的告訴你元素構成,有的告訴你同位素比例。諾蘭關心的不只是有什麼,還有各有多少,以及同一元素的不同同位素各佔多少。

有意思的地方就出在最後這一項。

他講了烏巴圖巴(Ubatuba)那個案例。巴西海邊,一個漁夫看到一個物體掉出什麼東西,或者直接爆開了。落下的東西是比較純的鎂,純到會燒起來,所以裡面一定摻了別的金屬做成合金,防止它燒掉。

諾蘭拿到兩塊樣品,來自兩條不同的保管鏈,都聲稱出自同一個物體。肉眼看,兩塊東西長得一樣。他各取了一小片,送進二次離子質譜儀,這種儀器能分辨到 0.0001 個質量單位。

結果分成兩組。一組鎂 24、25、26 的同位素比例完全正常。另一組偏得厲害,而且兩塊樣品偏得一樣多。

這就等於你手上有了一個內部對照,一邊是正常值,另一邊是錯的。(加里·諾蘭)

他沒法給出結論。是騙局嗎?如果有人存心造假,做得到,但成本不低。按那個年代的價格,他手上那點量就要幾萬美元。而且造假圖什麼?圖三十年後的某個陌生人撿起來研究?這是一種極其耐心的惡作劇。

諾蘭說自己也不知道該怎麼理解,只知道它有意思。

他順手把話題帶到"什麼才算證據"上。這夠嗎?遠遠不夠。但有人把它擺出來了,他有時間,就研究。他的做法是挑出那些他認為足夠可信的樣本做合理分析,把結果公開,也許別人能想出他沒想到的解釋。

更好的證據是什麼?是某種一看就知道是技術、而且是我們沒有的技術。尼爾·德格拉斯·泰森(Neil deGrasse Tyson)和塞斯·肖斯塔克(Seth Shostak)都公開說過這個立場:你拿出明顯不是我們理解範圍內的技術,我們就認真對待。

諾蘭同意,而且補充說,他研究過的一些東西最後查明平凡得很,有些乾脆是 1940 年代飛機上的零件。

但他也指出這件事的難度:外星人拿出一種我們完全陌生的技術,很難被認成技術。太新了,我們不會認為它是技術;太熟了,就不算證據。怎麼讓螞蟻相信,是個硬問題。你得先搞懂螞蟻在聊什麼,在乎什麼,才能把自己的資訊注入它們的文化。

瓦萊:一場演給文化看的戲

主持人問起雅克·瓦萊(Jacques Vallée)。諾蘭說自己在阿塔卡馬事件之後不久認識了他,是透過一批和政府有關聯的人,那批人當時正在私下裡和瓦萊合作。

瓦萊從上世紀六十年代起就在這個領域公開活動,是少數真正的科學家之一。

諾蘭從他那裡學到的第一件事,是"歌舞伎劇場"(Kabuki theater)這個概念。人們看到的很多東西是被演出來的。

他讀瓦萊的書時注意到一個詞反覆出現:荒誕。飛船不會降落在農田裡,然後有人敲門要一杯水。這類故事在 1930 年代的報紙上就有。也沒道理飛船會墜毀,技術那麼先進,怎麼會墜毀。荒誕本身就是線索,說明這是一場表演,一場影響力運動。

它瞄準的是一整個文化,個人級別的說服解釋不了它。也許它們根本不把我們當個體看,而是當成一顆行星上生活的一個生物體。(加里·諾蘭)

這個說法讓諾蘭第一次意識到,幕後可能有個操縱者,而所有關於"外星人"的敘事本身未必為真,它可能只是一種被設計出來的表現形式。

他也吐槽了和瓦萊聊天的體驗:這人有意思,也極其難纏,會把你以為你知道的一切拆開,證明你其實不知道。瓦萊的一個方法論是,對於任何結論,只要找到一個反例,你就錯了。

諾蘭說自己名義上也算個好科學家,但從瓦萊身上學到的是:別談結論,只談資料。資料不會錯,前提是你確認它沒有錯、不是偽影。結論要小心,因為不管正在發生什麼,它都比我們想象的複雜得多。

2021 年那份報告,和背後那場拉鋸

2021 年 6 月,美國國家情報總監辦公室釋出了《不明航空現象初步評估》(Preliminary Assessment: Unidentified Aerial Phenomena)。

諾蘭的判斷是很樂觀。他的說法是,成年人終於站出來接手了,是褒義上的成年。

他提到另一件事:之前有人擔心,一旦公開,大眾會尖叫著上街暴亂。經驗證據顯示這個擔心是錯的。這些影片公開已經五年,多數人根本不知道。哪怕福克斯新聞的塔克·卡爾森講過很多次,喬·羅根也講過,還是有很多人不知道。人只要覺得這件事不影響自己的日常,就繼續過日子。

但這份報告在政府內部是一次真正的轉向。諾蘭認為部分原因是人類社會技術的成熟,這些東西一次又一次出現在自家艦船周圍,瞞不住了。盧·埃利宗多(Lou Elizondo)和克里斯·梅隆(Chris Mellon)等人的功勞在於找到了正確的說話角度:好吧,假定不是"那個東西",那可能是俄羅斯或者中國,我們總該弄清楚,因為我們確定不是自己。

然後是國防部正式設立辦公室來歸集這些資訊,後來那個拗口的名字叫機載物體識別與同步管理小組(Airborne Object Identification and Management Synchronization Group,簡稱 AOIMSG)。諾蘭的評價很直白:名字很蠢,需要改。

他說幕後關於誰控制這個辦公室的拉鋸還在繼續,但錢已經撥出來了,會用於讓資訊更公開,讓更多人參與。他自己也在參與一個推動更多學者加入的努力。

這裡他講了一段自嘲。他說科學家本質上是資本主義者,錢在哪裡人就去哪裡。他自己那篇論文花了五六萬美元,全是從自己口袋裡掏的。而要做像樣的材料分析,至少需要幾百萬美元。伽利略計劃那邊要完成任務,大概在五百萬到一千萬美元的量級。

主持人反駁了一下這個詞用得不準確:基礎研究裡,錢的影響其實很模糊,科學家很擅長編一個敘事說自己是在完成資助方的目標,實際做的還是自己好奇的事。諾蘭承認這個說法也有道理,他小時候想當植物學家,後來大部分生物學家去做癌症研究,一個重要原因是那裡有錢。

他真正想說的是另一件事:最糟糕的做法是把這件事塞進一家有既定計劃的公司裡,讓科學家聽高管的。真正能出成果的方式,是把它放到公共領域,讓開放的頭腦去想,去發表,去做對的工作。

奧陌陌、光帆,和先想象再倒推

訪談裡提到阿維·勒布(Avi Loeb)和奧陌陌(Oumuamua)。諾蘭的評價是:勒布的洞察是一個有意思的推測。有人看一眼就說那是小行星,結束。但資料裡有某個不對勁的地方,勒布抓住了它,提出一個替代解釋,而這個解釋和模型擬合得比"一塊石頭"更好。

他佩服勒布的地方在於無視批評。勒布相信資料是真的,然後把這當成攻城錘去砸別的東西。

奧陌陌的核心假設之一是光帆。諾蘭說光帆完全在人類能力範圍內。尤里·米爾納(Yuri Milner)參與的突破攝星計劃,思路就是用鐳射把光帆推向半人馬座。所以勒布的提案在可能性範圍之內。可惜的是,那個東西現在已經快飛出太陽繫了。

諾蘭由此說到方法。他的實驗室有個習慣:先問什麼是必然的。如果必然需要某類資料,而現有儀器不存在,那就先想象一臺完美的儀器,雖然造不出來,但可以從那裡往回倒推,找到可行的路徑,等於逆向工程自己的未來。他用這個思路創辦和賣掉過至少六七家公司。

他舉的例子是基因治療。今天所有用逆轉錄病毒做的基因治療,源頭是大衛·巴爾的摩(David Baltimore)實驗室的一次組會。當時另一位博士後做不出想要的逆轉錄病毒,諾蘭意識到自己手上有一個細胞系,能讓這件事從兩個月縮短到兩天。兩人合作做出了那套系統,後來全世界都在用。

一開始你得相信這項技術是可能的,才可能把它造出來。(加里·諾蘭)

他把這套邏輯套在 UFO 上:這個現象讓人們去想象一個這些技術已經存在的未來,也去想象一個人類沒有把自己炸掉的未來。如果這些東西真的在那裡,說明至少有一個文明跨過了那個拐點。

至於它們為什麼來,諾蘭給的可能性之一是,把我們從這個懸崖邊上引開。就像鄰居家的孩子長大了,你希望他別太野。也可能是某種道德律令,像我們劃出國家公園讓動物按自己的方式活下去。

但他馬上加了一句限制:外星就是外星,不是好萊塢那種外星,是一整套不同的思維方式和經驗層次,我們只能希望自己有一天能理解。

他還提了一個更遠的設想。文明越發展,形態越接近資訊本身,越像是能影響觀念空間的東西。我們人類執著的"具身"(embodiment),看得見摸得著的實體,可能是一種很低效的形態。想想人工智慧領域正在做的事,電路越做越小,逼近宇宙運作的物理底層,量子計算已經貼著量子資訊儲存了。往前推一萬年十萬年,也許有文明找到了把智慧直接嵌進宇宙物理裡的方法,不需要物質形態,只是區域性有序的時空。

那樣的話,它們必須非常擅長不踩到螞蟻。技術越好,越容易一不留神把這種簡單的生物系統毀掉。

還有一層。我們總假設它們是統一的,也許它們彼此之間就像你和我一樣分歧巨大,而阻止某一家亂來的,正是其他幾家之間的相互牽制。地球上國家之間的無政府狀態,在更大的尺度上可能同樣成立。一層層的智慧構成等級,每一層都在想:比我更大的那個是什麼。

阿塔卡馬骨架:一次不動聲色的證偽

史蒂文·格里爾(Steven Greer)曾聲稱在智利阿塔卡馬地區發現的一具骨架可能是外星人。諾蘭主動聯絡,接下了用科學方法證實或證偽這件事。

最後的論文標題是《阿塔卡馬骨架全基因組測序揭示與發育不良相關的新突變》。團隊包括兩位斯坦福科學家和羅氏診斷的測序組,總共十一人左右。按這行的慣例,教授不幹活,學生幹活,教授幫忙把故事講圓。

結論很簡單:百分之百是人類。諾蘭說自己一開始以為那是某種猴子,幾個月後還小小地興奮過一下:萬一真是外星的呢。

骨架的特殊之處主要在腦部畸形。他拿到照片後第一件事是找斯坦福的專家,那人是兒童骨發育不良領域的世界級權威,這個領域的教科書就是他寫的。專家的判斷是,這套突變組合和這種生理形態他沒見過的,但按大小和骨密度看,像是六到七歲。

諾蘭特意在這裡停了一下。他說公眾經常把這種推測當成事實,沒人說過它就是那個年齡,只說過骨頭看起來像那個年齡。論文裡的措辭也做足了限定,說的是這些突變可能導致這樣的形態。

他們真正發現的是,這個個體身上與骨骼生長相關的突變數量異常多。就是骰子擲壞了。每年出生的人那麼多,擲得足夠多次,總有人一次把所有壞點數擲齊。

讓他覺得難過的是 UFO 社群裡的部分人,他們希望這裡面有陰謀,希望有人收買了他的學生去說謊。他說這不可能,他自己會丟工作,學生們一輩子都會麻煩纏身。

他還有一句話說得更重:這是把惡意投射到一群並不存在惡意的人身上,尤其是在科學界。做科學的人可能天真,可能不關心大圖景、哲學、倫理問題,但歸根到底是有操守的人,帶著對發現酷東西的純粹好奇。科學界整體上沒有惡意。

他還順帶拆了"打假"這個詞。有人說他在阿塔卡馬事件上是在 debunking,他說這個詞本身帶預設,暗示你一開始就奔著證明某樣東西是假的去。他沒有。他只是去收集資料,然後發現這一個是人類。

另一具頭骨,有人叫它"星孩"(Star Child),他看了測序結果,直接說這是人類,到此為止。持有者不同意,後來另一個團隊進來,證明他是對的。

諾蘭把這件事的意義說得很清楚:把那些最誇張、最被炒作的案例從桌上拿掉,動機是想知道,跟否定無關。越是離譜的東西越可能是錯的。清掉渣滓之後,剩下的資料裡也許有值得認真追的東西,而如果追得夠深,那東西本身也許同樣驚人。

他舉了 CRISPR 作為對照。細菌基因組裡那些奇怪的重複序列,一段段排在一起,中間夾著奇怪的片段,仔細看那些片段,長得像病毒。它們怎麼進去的?花了大量工夫之後,幾個諾貝爾獎發出去了。那些奇怪的東西最後帶來了極其驚人的可能性。

你想用科學的嚴謹,去把那個驚人的東西真正揭示出來。(加里·諾蘭)

同位素比例為什麼值得追問

回到材料。諾蘭解釋了為什麼同位素比例這個指標有分量。

任何一種元素的同位素比例,基本由恆星過程決定。幾十億年前某顆超新星爆炸,物質變成雲,引力讓它們聚成另一顆太陽和一個環,環變成岩石行星。比例在那次爆炸的時刻就定下來了。所以本地太陽系裡所有東西的比例大差不差,差異在千分之幾的量級,不動輒就是幾十個百分點。

那人類用同位素做什麼?他說,主要是用來炸東西。按磅按噸製造出來的同位素,絕大多數是特定比例的鈽和鈾。今天工程化調整同位素比例技術上不算難,但依然昂貴。除了核爆,還有抗癌藥物之類的用途。

然後他講了一個細節,這個細節是整個論證裡最鋒利的一處。他說現在用同位素做防偽,把錢或者貴重物品裡嵌入特定比例的同位素,讓造假者難以下手。除此之外,日常生活裡沒人會特意去調整同位素比例。

那為什麼會有人造出幾克這種材料,然後把它丟在巴西的一處海灘上?

這個問題他沒能回答,也沒打算假裝能回答。他只是把它擺在那裡。

當目擊者看到的和照片拍到的不是同一個東西

主持人問他,聽過的最有衝擊力的一次遭遇報告是什麼。

除了辛巴威那件,諾蘭講了一個幾乎沒人知道的案例。

一家人開車在公路上,兩個小女孩坐在後排,車是玻璃頂的。大白天的繁忙公路,兩個女孩看到一艘飛行器就在她們車頂上方。母親也看到了。她們環顧四周,其他人似乎什麼也沒看見。女孩拿出手機拍了照片。

回家看照片,飛行器不在。但在車頂上方大約三十英尺處,有個小東西,直徑大概三英尺,有點像個星形。那不是她們看到的飛行器,是另一個東西。

諾蘭說他看過那張照片。

那她們看到的是什麼?投影?為什麼只有她們看得到?照片捕捉到的東西和肉眼看到的東西完全不是一回事,但照片裡確實有東西。

他說這個案例不符合任何一個標準敘事,但恰恰是這種不符合讓他著迷。它清楚地說明了另一件事:人看到事件時,看到的並不都一樣。交通事故的目擊者會對車的顏色、事件的順序給出不同描述,這說明記憶遠沒有我們以為的可靠。

但 UFO 報告的特殊之處在於,同一批人看到的差異大到讓人懷疑,有什麼東西把影像直接投進了腦子裡,而物質世界裡其實並沒有擺著東西。就像一套被強行施加的虛擬現實。

Meta 和所有做虛擬現實的公司都會很想要這種技術。你不需要在臉上戴任何裝置,就能體驗虛擬現實。(加里·諾蘭)

怎麼跟螞蟻說話

從這裡開始,諾蘭把溝通問題拆成了一個感知工程問題。

他說,如果你要操縱螞蟻,比如把它們當生物機器人用,DARPA 這類機構一直在試,那你就必須先接入它們的資訊通道,也就是資訊素系統。要麼合成那些分子去跟它們"說話",要麼技術足夠先進,用電磁或其他手段直接刺激神經元,達到和資訊素一樣的效果,只是走的是遠端操控的路子。

對人也是同樣的邏輯。你可以把資訊遠端送進人的感官系統。但每個人都不一樣,你要麼對這個人瞭解到能定製,要麼就利用這個人本身最強的那個感官通道。如果你對聲音敏感,資訊就從聲音進來;如果你是視覺型,就從畫面進來。

主持人在這裡加了一條他認為外星人必須搞清楚的約束:人類重視物理一致性。我們發現了物理定律,所以我們要求感知結果是自洽的。諾蘭同意,並說這恰恰是難點所在。什麼東西是人類在這個環境裡習慣看到的,怎麼刺激感知系統才不至於突破"太怪了"那個閾值。這並不顯然。也許反過來,就該往怪裡走。

由此他談到了"灰人"(grays)。諾蘭說他本人不相信灰人,但他相信有人確實看到了。有意思的地方在於灰人的形象設計:它們足夠不一樣,但不至於嚇人,沒有滴著毒液的獠牙。它們身上還有一種熟悉感,像是你能想象的人類在遙遠未來的樣子。

如果這是一套溝通策略,那它傳遞的訊號就是:我們像你們,但不完全一樣。諾蘭不知道這是不是有意的,但作為溝通設計來看,它成立。

那段影片讓他汗毛豎起來

主持人問起 Tic Tac 影片和其他飛行員目擊事件。

諾蘭說他認識這批人裡的很多。他是在影片公開前大約三週看到的。水晶城一家能俯瞰五角大樓的酒吧裡,盧·埃利宗多把影片放給他看,他說自己汗毛都立起來了。盧告訴他,這些東西快要公開了。

他還認識內部的一位海軍情報人員,那人在公開前重新訪談過所有涉事飛行員。諾蘭說聽

諾蘭說聽那些內容讓人頭皮發麻,同時也興奮,因為這不只是口述證詞,這些人是可信的個體。他提到《60 分鐘》那期節目,那些飛行員沒有任何經濟收益,站出來只有損失。

再加上普林斯頓號同時期的艦載分析、雷達資料等等。諾蘭的總結是:說到底這只是資料,不是結論。他補了一句真心話:如果有人證明這一切都是騙局,他會非常高興,那樣他就能回去幹本職工作了。

這件事可能是假的,別的事未必。這正是去汙名化的意義所在。異常事件在資料裡本來就是稀少的,但你必須看完整的資料範圍,才能發現那些真正指向某個東西的訊號。

他還說了一個副作用。過去一年他公開談這些之後,一些頂尖學校的學生,不是他自己的學生,跑來找他說:如果能幫忙,告訴我。我以前沒想過這件事,是你和別人讓我開始想。

這就是他看重的東西。哪怕這些資料不代表外星飛行器,光是這個觀察本身就能激發人。有人會因此去想:如果無動量推進是可能的呢?有年輕人會因此進科學界去問那些問題。

訪談末尾主持人提到,有意思的是馬斯克對這類可能違反已知物理的推進系統不太上心。諾蘭沒有接這個話頭,他的立場更簡單:先相信技術是可能的,才可能把它造出來。

拉扎爾的故事,和他的不感興趣

主持人問他怎麼看鮑勃·拉扎爾(Bob Lazar)關於美國政府持有飛行器的說法。

諾蘭直說不信。他承認傑里米·科貝爾(Jeremy Corbell)做的訪談和紀錄片很好,但他不知道該怎麼解讀。他身邊一些人認為是垃圾。

他借這個問題講了自己和這個領域裡很多人的方法差異:他對翻舊檔案、追查誰在什麼時候說了什麼,興趣不大。他是科學家。他做腦部那塊,是因為那能收集資料:能回到同一個人身上再掃一次核磁,能把影像交給別人分析,能拿到材料做檢測,能讓別人復現。

他順口說了一句"我再也不碰任何骨架了"。這句帶過的話很輕,但能聽出來是被折騰過。

主持人替拉扎爾說了句公道話:拉扎爾這麼多年的說法基本沒變過。而且這類故事對推動政府透明有實際影響。諾蘭承認這一點,也承認人這個因素繞不開。異常事件是稀有的,一部分資料不可避免地和人綁在一起,比如飛行員的直接目擊。他希望未來感測資料不再被人的主觀性汙染,但人的觀察本身仍然是強資料。

如果他在位

主持人問了一個假設:美國政府或者其他政府是不是掌握了某種遠超公開水平的外星來源的東西?

諾蘭說他本人沒見過,但他相信那些他認為不會說謊的人。所以答案是有。

那如果他在位,會公開嗎?他說會。他認為這類知識能讓人團結起來,因為我們和"那個東西"比起來,彼此更像,不像彼此那麼不同。

他也不主張清算。那些年做過決定的人,是基於當時手上的資料做的,有他們的理由。該給的是某種豁免。只有一種情況另說:如果動機是私利,為了自己變現而損害別人。

但他也誠實地說,真坐到那個位置上,可能會有人給他看一些東西,告訴他為什麼不能公開。比如無限能源,一旦公開,也許某個關係緊張的國家先搞明白了。這本質上是一場軍備競賽,各個層面都是。

他由此說了一段不太像科學家說的話。新冠病毒的起源,在他看來,不管真相如何,中國政府有興趣不公開,因為公開只會對它不利。每個政府都這麼想。他說自己和公司裡的公關打交道時也失望過,他們總是緊張,總是保守,總擔心多公開一點只會更糟。然後來了個馬斯克,發一堆荒唐的梗圖,完全不在乎。

他一直在鼓勵 CEO 們透明一點。當然政府涉及國家安全,是另一個層級,人命關天。但可以從輕的地方開始,比如把技術是怎麼做出來的講出來。這會讓人興奮,會把人連起來,對品牌也好。

那種"資訊被偷走就會被用來對付你"的擔心,是二十世紀的想法。(加里·諾蘭)

他認為社交世界帶來的好處之一,就是透明本身是有利的。他希望政府能學會這一課,當然政府通常是最後學會的。

羞恥是社會控制裝置

訪談最後,主持人問他給年輕人的建議。

諾蘭的回答很直接:如果你相信某件事有價值,就別讓別人用羞恥感把你勸退。他說羞恥是一種社會控制裝置,讓別人做他們想讓你做的事,而把你的意願擠到一邊。羞恥有時候有用,能阻止你做不道德的事,但它同時也在給你的環境劃邊界。

他遇到過一位很有名的科學家告訴他,談這些東西會毀掉他的職業生涯。事實是,這事反而提升了他的職業生涯。

主持人在這裡加了一條自己的觀察:科學上很多進展,恰恰是某個資深前輩說"這會毀掉你的職業生涯"之後做出來的。這句話本身可能就是一個不錯的訊號。諾蘭同意。

他帶實驗室的方式也是這個邏輯。他的實驗室從 1992 年起一直是二三十人的規模,人來了又走。他常跟學生說,落在趨勢線上的資料沒那麼有意思,真正值得追的是偏離圖表的那一個點。偏離意味著發現。他講自己在組會上叫停過很多次:等一下,往回翻幾頁,剛才那個是什麼。那些時刻後來成了不少人的職業生涯轉折點。

至於壓力,他的應對方式是用成果反推。他會直接說:當年勸我別創業的是你們,現在來問我怎麼創業的也是你們。從科學上說,你想把一個可能的解釋從桌上拿掉,這算哪門子的科學方法?

他也承認這條路會孤獨。科學是一個共同體,當你走在常規思路之外,孤獨是常態。九十年代做神經網路的人也是孤獨的。

但他給出了另一面:因為這件事,他認識了這輩子最有意思的一批人,如果一直走常規路線,他不會遇到他們。他去波士頓的哈佛或 MIT 做講座,晚飯時這個話題總會冒出來,然後桌上一定會有另一個人承認自己感興趣,或者承認自己見過什麼。整個談話的氣氛立刻變了。也有人飯後單獨過來,說我不公開談這個,但是……

知道"還有別的東西"的科學家,數量遠比科學界願意承認的要多。(加里·諾蘭)

島嶼與船帆

最後主持人問他,這一切對人類的意義是什麼。

諾蘭的比喻是這樣的:你在一座島上住了一輩子,望著海對岸,從沒想過另一座島上也可能有人。然後某天,一艘帶帆的船出現了。你聽不懂它,但你意識到,你的世界突然變大了。

他說我們現在就在這樣一個時刻,世界觀、銀河系的圖景正在向更大的東西開啟。不只是"可能還有別人",還有"還有別的東西",而它是什麼,還沒有答案。

沒答案這件事本身讓他興奮,因為那意味著他可以用自己的想象去填。

這個發現會讓人類更謙卑,也會讓人類更有趣。當我們向外看,意識到自己一直住在島上,我們會同時變小和變大。

主持人接了一句:可以看著外面的星星,想象那裡還有什麼。雖然知道自己永遠看不到全部,但知道它在那裡,這件事就足夠讓人激動。

如果你也想往裡看一步

這期訪談裡,諾蘭真正提供的不是結論,是一套做法。如果讀完之後你想做點什麼,可以從這幾件事開始。

  • 區分資料和結論。諾蘭反覆強調,他只對資料負責,結論隨時可以被一個反例推翻。看到任何一方的強斷言,先問一句:原始資料在哪裡,誰採集的,能不能復現。
  • 遇到"最誇張的版本",先想著把它從桌上拿掉。阿塔卡馬骨架、星孩頭骨,都是先被清出討論範圍,才讓後面的追問有意義。越是聳動的說法越可能出錯,早一點排除,省下的時間才用在真東西上。
  • 留意身邊那些"說不上哪裡不對"的偏離點。諾蘭實驗室的方法論很樸素:趨勢線上的資料不值得激動,掉出圖表的那一個點才值得。這個習慣在工作裡同樣管用。
  • 別被"這會毀掉你的職業生涯"勸退。如果一位資深前輩用這句話攔你,先別急著聽。諾蘭自己的經歷是反過來的,他遇到的那位權威錯了。
  • 想參與的話,公開的資料採集專案比圍觀更有用。諾蘭加入了伽利略計劃,理由很簡單:名單上沒有生物學家。找一個你能貢獻專業視角的位置,比等著別人給答案更實際。
  • 對他人的遭遇保持最低限度的禮貌。七到十歲的孩子不會串供,幾十個孩子畫出同樣的圖,這件事本身就是一個待解釋的資料點。你不需要相信它是什麼,但也不必急著宣佈它是假的。
  • 做重大判斷時,給自己留一次"往回翻幾頁"的機會。諾蘭在組會上叫停學生的那個動作,成本幾乎為零,收益是幾個人的職業生涯。審閱別人的方案、覆盤一次失敗、重看一段資料,都可以先問一句:剛才那個是什麼。

訪談結尾,主持人引了斯坦尼斯瓦夫·萊姆《索拉里斯星》裡的一句話:我們連彼此都理解不了,還指望怎麼和一片海洋溝通?

這句話放在兩個多小時的對談之後,位置剛剛好。諾蘭整場都在講怎麼和螞蟻說話,講到最後,問題還是落回我們自己身上:我們連自己那套從 DNA 裡長出來的預期都還沒搞明白。

How would you, as a higher intelligence, represent yourself to a lesser intelligence? Do you think they saw what they say they saw? It didn't just start showing up in 1947. How hard do you think it is for aliens to communicate with humans? What do we believe in? We believe in technology. So you show yourself as a form of technology, right? But the common thread is you're not alone. And there's something else here with you. And there's something that's, as you said, watching you. You are a professor at Stanford studying the biology of the human organism at the level of individual cells. So let me ask first the big, ridiculous philosophical question. What is the most beautiful or fascinating aspect of human biology at the level of the cell to you? The micromachines and the nanomachines that proteins make and become, that to me is the most interesting. The fact that you have this basically dynamic computer within every cell that's constantly processing its environment, and at the heart of it is DNA, which is a dynamic machine, a dynamic computation process. People think of the DNA as a linear code. It's codes within codes within codes. And it is actually the epigenetic state that's doing this amazing processing. I mean, if you ever wanted to believe in God, just look inside the cell. So DNA is both information and computer. Exactly. How did that computer come about? A big continuing on the philosophical question. Is this both scientific and philosophical? How did life originate on Earth, do you think? How did this, at every level, so the very first step and the fascinating complex computer that is DNA, that is multicellular organism, and then maybe the fascinating complex computer that is the human mind? Well, I think you have to take just one more step back to the complex computer that is the universe, right? All of the so called particles or the waves that people think the universe is made of and appears, to me at least, to be a computational process. And embedded in that is biology, right? So all the atoms of a protein, et cetera, sit in that computational matrix. From my point of view, it's computing something. It's computing towards something. It was created, in some ways, if you want to believe in God, and I don't know that I do, but if you want to believe in something, the universe was created or at least enabled to allow for life to form. And so the DNA, if you ask, where does DNA come from? And you can go all the way back to Richard Dawkins and the selfish gene hypothesis. The way I look at DNA, though, is it is not a moment in time. It assumes the context of the body and the environment in which it's going to live. And so if you want to ask a question of where and how does information get stored, DNA, although it's only 3 billion base pairs long, contains more information than, I think, the entire computational memory resources of our current technology. Because who and what you are is both what you were as an egg all the way through to the day you die, and it embodies all the different cell types and organs in your body. And so it's a computational reservoir of information and expectation that you will become. So actually, I would sort of turn it around a different way and say, if you wanted to create the best memory storage system possible, you could reverse engineer what a human is and create a DNA memory system that is not just the linear version, but is also everything that it could become. When we're talking about DNA, we're talking about Earth and the environment creating DNA. So you're talking about trying to come up with an optimal computer for this particular environment. Right. So if you were to reverse engineer that computer, what do you mean by considering all the possible things it could become? So who you are today, right? So 3 billion bits of information does not explain Lex Friedman, doesn't explain me, right? But the DNA embodies the expectation of the environment in which you will live and grow and become. So all the information that is you, right, is actually not only embedded in the DNA, but it's embedded in the context of the world in which you grow into and develop, right? But so all that information though is packed in the expectation of what the DNA expects to see. Interesting. So like some of the information, is that accurate to say is stored outside the body? Exactly, yeah. The information is stored outside because there's a context of expectation. Isn't that interesting? Yeah, it's fascinating. I mean, to linger on this point, if we were to run Earth over again a million times, how many different versions of this type of computer would we get? I think it would be different each time. I mean, if you assume there's no such thing as fate, right, and it's not all pre programmed, and that there is some sort of, let's say, variation or randomness at the beginning, you would get as many different versions of life as you could imagine. And I don't think it would all be unless there's something built into the substrate of the universe. It wouldn't always be left handed proteins, right? But I wonder what the flap of a butterfly wing, what effects it has, because it's possible that this system is really good at finding the efficient answer, and maybe the efficient answer is, there's only a small finite set of them for this particular environment. Exactly, exactly. That's the kind of, in a way, the anthropomorphic universe of the multiverse expectations, right? That there's probably a zillion other kinds of universes out there if you believe in multiverse theory. We only live in the ones where the rules are such that lifelike hours can exist. So using that logic, how many alien civilizations do you think are out there? There's like trillions of environments, aka planets, or maybe you can think even bigger than planets. How many lifelike organisms do you think are out there thriving, and maybe how many do you think are long gone, but were once here? I think, well, innumerable, I think in terms of the present. Greater than zero. Much greater than zero. I mean, I would just be surprised. What a waste, right, of all that space just for us if we're never gonna get there. That would be my first way to think about it. But second, I mean, I remember when I was about seven or eight years old, and I would love if any of your listeners could find this National Geographic. I remember opening the page of the National Geographic. I was about, again, seven to 10 years old, and it was sort of a current picture of the universe. It was around probably 1968, 1969. I just remember looking at it and thinking, what kinds of empires have risen and fallen across that space that we'll never know about? And isn't that sad that we know nothing about something so grand? And so I've always been a reader of science fiction because I like the creative ideas of what people come up with. And I especially like science fiction writers that base it in good science, but base it also in evolution. That if you evolve a civilization from something lifelike, right, some sort of biology, its assumptions about the universe will come from the environment in which it grew up. So for instance, Larry Niven is a great writer, and he imagines different kinds of civilizations. In some cases, what happens if intelligence evolved from a herd animal, right? Would you lead from behind, right? Would you be, you know, in his case, one of them were the so called puppeteers. And to them, the moral imperative is cowardice. You put other people forward to run the risk for you, right? And so he writes entire books around that premise. There's another guy, Brin, David Brin is his name, and he writes the so called uplift universe books. And in those, he takes different intelligences, each from a different evolutionary background. And then he posits a civilization based around where and what they came from. And so to me, I mean, that's just fun. But I mean, back to your original question is how many are there? I think as many stars as we can see. Now, how many are currently there? I don't know, I mean, that's the whole question of, you know, how long can a civilization last before it runs out of steam? And you, for instance, does it just get bored or does it transcend to something else? Or does it say, I've seen enough and I'm done? What does running out of steam look like? It could be destroy itself or get bored. You know, or we've done everything we can and they just decide to stop. I don't know, I just don't know. It's that you all must worry that we stop reproducing or we slow down the reproduction rate to where the population can go to zero. We can go to zero and we can't and we collapse. I mean, so the only way to get around that is perhaps create enough machines with AI to take care of us. What could possibly go wrong? You've talked to people that told stories of UFO encounters. What is the most fascinating to you about the stories of these UFO encounters that you've heard that people have told you? The similarity of them, the uniformity of the stories. Now, I just wanna say upfront, a lot of people think that when I speculate, I believe something, that's not true, right? Speculation is just creativity. Speculation is the beginning of hypothesis. None of what I hear in terms of the anecdotes do I necessarily believe are they true? But I still find them fascinating to listen to because at some level they're still raw data and you have to listen. And once you start to hear the same story again and again, then you have to say, well, there might be something to it. I mean, maybe it's some kind of a Jungian background in the human mind and human consciousness that creates these stories again and again as coming out of the DNA, it's coming out of that pre programmed something. And Jung talked quite a bit about this kind of thing. The collective unconscious. But actually one of the most interesting ones I find is this constant message that you're not taking care of your world. And this came long before climate change. It came long before many kinds of, let's say current day memes around taking care of our planet, pollution, et cetera. And so, for instance, perhaps the best example of this, the one that I find the most fascinating is a story out of Zimbabwe, 50 or 60 children, one afternoon in Zimbabwe. It was a well educated group of white and black children who had lunchtime in the playground, saw a craft and they saw little men. And they all ran into the teachers and they told the same story and they drew the same pictures. And the message several of them got was you are not taking care of your planet. And it got, you know, there's actually a movie coming out on this episode and 30 years later now, the people who were there, the children who've now grown up say, it happened to us. Now, did it happen? Was it some sort of hallucination or was it an imposed hallucination by something? Was it material? I don't know, but these kids were seven to 10 years old. You see them on video. Seven to 10 year olds can't lie like that. And so, you know, whether it's real or not, I don't know, but I find that fascinating data. And again, it's these unconnected stories of individuals with the same story. That is worthy of further inquiry. Yeah, so here we are humans with limited cognitive capacities trying to make sense of the world, trying to understand what is real and not. We have this DNA that somehow in complex ways is interacting with the environment. And then we get these novel ideas that come from the populace. And then they make us wonder about what it all means. And so how to interpret it. If you think from an alien perspective, how would you communicate with other lifelike organisms? You perhaps have to find in points on this interaction between the DNA and its manifestations in terms of the human mind and how it interacts with the environment. So it gets some kind of, all right, what is this DNA? What does this environment have to get in somehow to like interact with it, to perturb the system to where these little ants, human like ants get like excited and figures and see stuff out. Yeah, it has, and then somehow steer them. First of all, for investigative purposes, understand like oftentimes to understand a system, you have to perturb it. Exactly, yeah. It's like poke at it to get excited or not. And then the other ways you want to, if you worry about them, you can steer in one direction or another. And this kind of idea that we're not taking care of our world, that's interesting. I mean, that's comforting, that's hopeful because that means the greater intelligence, which is what I would hope would want to take care of us. Like we want to take care of the gorillas in the national parks in Africa. Yeah, but we don't want to take care of cockroaches. So there's a line we draw. So you have to hope that. Right now we're a bunch of angry monkeys and maybe whatever these intelligences are, are also keeping an eye on us. That you don't want a bunch of, you don't want the angry monkey troop stomping around the local galactic arm. Do you think these folks are telling the truth? Do you think they saw what they say they saw? I think they saw what they said they saw, but I also think they saw what they were shown. I mean, if you go back to the whole notion of, okay, how long has this been around? It didn't just start showing up in 1947, right? There are stories going back into the 1800s of people who saw things in their farming, in their farm fields in the US. It's in local newspapers from the 1800s, it's fascinating. But if you can go even further back, so to your point of how would you as a higher intelligence represent yourself to a lesser intelligence? So let's go back to pre civilization. Maybe you show yourself as the spirits in the forest and you give messages through that. Once you get a little bit more civilized, then you show yourself as the gods and then you're God. Well, we don't believe in God anymore necessarily, not everybody does. So what do we believe in? We believe in technology. So you show yourself as a form of technology, right? But the common thread is you're not alone and there's something else here with you. And there's something that's, as you said, watching you and at least watching over your shoulder. But I think that like any good parent, you don't tell your student everything, you make them learn and learning requires mistakes because if you tell them everything, then they get lazy. You've looked at the brains of, or information coming from the brain of some of the people that have had UFO encounters. What's common about the brain of people who encounter UFOs? So the study started with a group of, let's say a cohort of individuals that were brought to me and their MRIs to ask about the damage that had been seen in these individuals. It turns out that the majority of those patients ended up being, as far as we can tell, Havana syndrome. And so for me at least, that part of the story ends in terms of the injury, it's likely almost all Havana syndrome. That's somebody else's problem now, that's not my problem. But when we were looking at the brains of these individuals, we noticed something right in the center of the basal ganglia in many of these individuals that at first we thought was damage. It was basically an enriched patch of MRI dense neurons that we thought was damage, but then it was showing up in everybody. And then we looked and we said, oh, it's actually not. The other readings on these MRIs showed that actually that's living tissue. That's actually the head of the caudate in the pitamen. And at the time, and I remember even asking a good friend of mine at Stanford, who was a psychiatrist, what does the basal ganglia do? He said, oh, the basal ganglia is just about movement and nerve and motor control. I said, well, that's odd because these other papers that we were reading at the time started to suggest that it was involved with higher intelligence and is actually downstream of the executive function and involved with intuition and planning. And then if you think about it, if you're gonna have motor control, which is centralized in one place, motor control requires knowledge of the environment. You don't wanna move something and hit the table. Or if you're walking across a room, you want to be aware and cognizant we use stable isotopes and money these days as a counterfeiting tool. You basically embed certain ratios of isotopes in to make it harder for counterfeiters to accomplish. But other than that, we don't do anything with that. So why would you make grams of such material in this one case and drop it around on a beach in Brazil? So which case are we talking about? Describe that, because this is the Ubatuba case. Can you describe this case a little bit further, like what material we're talking about, just the full story of the case? It's an interesting one. It's an interesting one. So a fisherman saw an object that released something, or it exploded. And it was this relatively, I've got some big chunks of it, relatively pure magnesium with obviously something else in it because magnesium burns. So it had something in it that would, other metals, simple alloy that would prevent it from basically burning up. And so the question is, and so then we had two pieces that came from two different chains of custody, both claimed to be from the same object. At least physically, when you look at the two things, they look the same. So we took small fragments of each of them. We put them in an instrument called a secondary ion mass spec, which is an extremely sensitive instrument. And it can see down to 0.0001 mass units, which is important for, let's say, more arcane reasons. But it's a sensitive instrument. And so one of the chains of custody, we had two pieces from the same chain of custody, and then two pieces from the other chain of custody. One of them had completely normal magnesium isotope ratios, magnesium 24, 25, 26. And the other was off, not just slightly off, way off. And they were both off to the same extent. I mean, it was sort of like you had an internal control of what was normal. And you had this other one, which was wrong. And so you're left with kind of an open question. Was this a hoax? Were these two chains of custody, one of them a hoax, that somebody purposefully introduced those things? Because you could do it. It would cost a lot. I mean, at the time that this was found, I guess the 1970s or so, it might have been earlier, I forget, the amount that I had would have cost several tens of thousands of dollars to make. And again, it's not something you would just throw around. And why would you do it in the hope that some guy 30 years from then would pick it up and study it? Yeah, it's a very subtle, subtle troll. It's a long term plan. So I just don't know what to make of it, except it's interesting. So a different kind of question that you're asking is, what constitutes evidence? So is this sufficient evidence? Absolutely not. But somebody's put it forward. I have the time. It's my time. I'll study it. And my objective is to sort of take those that I think are credible enough and do a reasonable analysis, put it out there. And maybe somebody else will come up with an idea as to what it is. Now, what would be better is some sort of true technology, something that is obviously. We don't have it. And people like Neil deGrasse Tyson and Seth Shostak have come out rightfully and have said, when you show up with something really obviously technology that we don't understand, then we'll pay attention. Not just material. Not just material. A piece of metal is interesting. And several of the things that I've looked at and other things that people have come to me with, we've found to be completely banal or were actually pieces of aircraft that were invented back in the 1940s. And so take them off the table. But I think, again, I think showing up with technology that we humans would find completely novel is actually a really difficult task for aliens because it obviously can't be so novel that we don't recognize it for what it is. And I would say most of the technology aliens likely have would be something we don't recognize. So it's actually a hard problem how to convince ants. You first have to understand what ants are tweeting about. What they care about in order to inject into their culture. Because that's why I think it would be the technology that you could present is in the space of ideas, is try to influence individual humans with the encounters and try to, with this kind of thing that you mentioned about us not taking messages, about us not taking care of the world. It's difficult. I mean, for them to understand, you have to come up with trinkets that impress us. I mean, maybe the very technology, the fascination with the development of technology and the development of technology, the actual act of innovation itself is the thing that they're communicating. I mean, this is kind of what Jacques Vallée thinks about, is the role of... The control system, he calls it. The control system. Well, let me ask about Jacques. Who is he? You know him. Who is Jacques Vallée? What have you learned from him about life, about UFOs, about technology, about our role in the universe? Well, I met Jacques actually soon after the whole Atacama thing happened. I was visited by those people associated with the government and whatever around the Havana... What ended up mostly being Havana syndrome patients, but also Jacques at the same time. And they were actually working behind the scenes with each other, that, oh, here's this Stanford professor who is willing to talk about this stuff and investigate things. Maybe we should go talk to him. And he reached out through a colleague and he and I had lunch actually at the Rosewood Inn up on near Sandhill. So Jacques is one of the first openly active scientists, and he's really a scientist, in this area going back to the 1960s. And he's put forward a number of ideas, speculations about what it might be that people are interacting with. And the first thing that I learned from him is this notion of what he called Kabuki theater, that many of the things that people have seen are... I remember reading his books and thinking, he uses this word absurd a lot. He said, the things that people claim they see are absurd, right? A ship doesn't land in a farmer's field and then come up and knock on the door and say, can I have a glass of water? And these are stories literally out of newspapers from the 1930s. It's absurd. And the other thing that people say, ships don't crash. If you're so technologically advanced, you don't crash. It's absurd that they crash. So he says, this is put on as a show. It's an influence campaign, right? It's not meant to influence individuals. It's meant to influence a culture as a whole. Maybe they don't look at us as individuals. Maybe they look at us as an organism that lives on a planet, right? And perhaps rightly so. And so that's how you interact with them. That's how you influence them. So that was one of the first things that kind of took me back and realized, wow, there's actually... maybe there's a puppet master behind the scenes that's doing this influencing and that all this stuff about aliens is just not true, per se. They're just a representation of something that is meant to influence. So that was probably the most interesting. I mean, the man is brilliant. He's also, and I'm sorry, Jacques, he can also be incredibly annoying to have a conversation with because he will pick apart your arguments or anything that you think you know and show you why you don't know what you think you know. And he used the example that, for me, that is all you need is one counter example to any conclusion and you're wrong. And so I learned from him... I mean, I'm supposed to be a good scientist, but I learned from him, don't talk about conclusions, just talk about the data because data is not wrong. I mean, convince yourself that the data is not wrong or not an artifact, but be careful about your conclusions because whatever is going on, it's much more complicated than we imagine. Wow, that's powerful. Being able to always step back because we humans get excited. Yeah. We start to jump to conclusions from the data, but always step back. Well... Powerful, being able to always step back because we humans get excited. Yeah. We start to jump to conclusions from the data, but always step back. Well, in some of my Twitter feeds, when I dare to go on Twitter, are full of, well, when are you going to give us the answer? Science is not immediate. You're going to have to be patient. And even some of my science colleagues have said, well, where's the data? My answer to them has been, where's been your work to try to produce any? I'm not here to give you everything on a silver platter. We talked offline how much I love data and machine learning and so on. And it's been really disheartening to see the U.S. government not invest as much as they possibly could into this whole process. So let's jump to the most recent thing, which is what do you make of the report titled Preliminary Assessment, Unidentified Aerial Phenomena that was released by the Office of the Director of National Intelligence in June 2021. So this is what's like, okay, we're going to step back and we're going to like, where do we stand and where do we hope the future is? What do you make of that report? Is it hopeful? Is it? I see it as very hopeful, very hopeful. I think the adults are finally stepping up and being in charge, right? In the good sense of adult. What's that? In the good sense of adult. This childlike curiosity is a pretty powerful thing. That's true, yeah. But it's also, I think, the people who were worried that the populace at large might run screaming into the streets and riot, you know, have, you know, they basically, the empiric evidence is they're wrong. You know, these videos and all these things have been out for now, what, five years? Most people don't even know about it, right? So as hyped as it's been and all over the newspapers that it's been and et cetera, you know, even Tucker Carlson has talked about it many times on his news program. Joe Rogan has. A lot of people don't know about it. So I think people, if it's not affecting their day to day life, they're going on with their day to day life. So, but that said, I think it was an important sea change in the internal discussions going on in the government because, and the reason being, that I think this is actually partly true with the maturation of human social technology. It was becoming so obvious that this stuff was showing up again and again and again around our ships. They just couldn't keep it quiet anymore, right? And so it's like, we need to do something about it. And Lou Elizondo and Chris and others, to their great credit, found the right angle to talk about this. It says, well, okay, let's say it's not out there. Maybe it's the Russians, the Chinese or somebody else. We should know about this because we damn sure know it's not us. So that to me is an important thing to finally be a little bit more open about the matter. But like I often say, I'm not looking for people to give me permission to do anything. I'm just going to do the analysis myself with what I have. Avi Loeb has taken the same approach. He said, I'm not going to wait for the government to give me telescopic information about technologies or things that might be even on our own solar system. I'm just going to collect it myself. And that's the right way to do it, right? Don't wait for somebody else to give it to you. It's also possible to inspire a large number of people to do a wider spread data collection. Yes. I mean, you yourself can't do a large enough data collection that would, if you're talking about anomalous events, you should be collecting high resolution data about everything that's happening on Earth in terms of like, in terms of the kind of things that would indicate to you a strong signal that something weird happened here. And this is why governments can be good at funding large scale efforts. Yes. I mean, you know, NASA and so on, working with SpaceX, with Blue Origin, you know, fund capitalistic sort of fund companies, fund company efforts to do huge moonshot projects. Right. And in the same way, do huge moonshot data collection efforts in terms of UFOs. I mean, we're not, it needs to be like 10X, like one or two orders of magnitude more funding. Exactly. To do this kind of thing. And I understand on the flip side of that, if you make it about what are the Russians, whether the Chinese doing, you know, make it a question of geopolitics, it gets touchy. Because now you're kind of taken away from the realm of science and... Making it military. Making it military. Some of the greatest, this is what makes me as an engineer, makes me truly sad that some of the greatest engineering work ever done is by Lockheed Martin, and we will never know about it. Yeah. I agree. I agree. I wish we were, it was different, but it's the world we live in. You know, but related to that UIP task force announcement that you just said, you know, the bill was passed in the Department of Defense and now it formally establishes an office to collate that information and also to be transparent about it. Money is now set aside, right? What do you think of it, just in case people don't know, the DOD establishing new department to study UFOs called Airborne Naming Command. But yes, Airborne Object Identification and Management Synchronization Group. Do you know how to pronounce that? No, I do not. No. AOI MSG. It's stupid and needs to be renamed, but... AOI MSG. AO, all right, is directed by the Undersecretary of Defense for Intelligence and Security. What do you make of this office? Are you hopeful about this office? I think there's still a tug of war going on behind the scenes as to who's going to control this. But I do know, though, that money has been set aside that will be used to make things more public, right, to start to get others involved. And, you know, I'm involved with an effort to get other academics involved. So you think there might be some of that money could be directed towards funding maybe like groups like yours to do some research here. So they would be open to that, you think? I hope so. I mean, nothing is set in stone yet. So, you know, and I'm not hiding anything because I just don't know anything, right. But I do think that there will be public efforts. Now, there are being set up other private efforts to bring monies involved and to use that to leverage and get access to some of the internal resources as well. So what you're seeing is kind of an ecosystem building up in a positive sense of people who are willing to do the research. So, you know, before it would be you couldn't even go to a scientist and ask them to help. Now, if there's money, as I said before, scientists are essentially capitalists. We go where the money is. I mean, the work that I've done, I did out of my own pocket. And probably about $50,000, $60,000, $70,000 of money went into the paper we published out of my own pocket. But the amount of money that needs to go in is in at least the few millions to do a proper analysis of these materials. The work I know that the Galileo project is involved with, it's probably in the, you know, 5 to 10 million range to get stuff done. But that's actually a relatively modest amount of money to accomplish something that has been in the zeitgeist for decades. I should also push back a little bit on something you probably will agree with. You said scientists are essentially capitalists. What I've noticed is there's certainly an influence of money, but oftentimes when you're talking about basic research and basic science, the money is a little bit ambiguous to what direction you're doing the research in. And the scientists get really good at telling a narrative of like, yeah, yeah, yeah, we're fulfilling the purpose of this funding, but we're actually, they end up doing really what they're curious about. Yes. And of course you cannot deviate like if you're getting funded to study penguins in Antarctica, you can't start building rockets, but probably you can because you will convince some kind, you'll concoct a narrative saying rockets are really important for studying penguins in the Antarctic. Right. I think that's actually, this is one thing I think people don't generally understand about the scientific mind is I don't know how capitalistic it is because if it was, they would start an effing company. No, no, no, no. I mean, when I meant capitalist, I didn't mean in the, they'll start companies per se. I mean, we can only do the research where there's money. And so from, you know, maybe it's a bad use of the term capitalist. But we will only do the research where there's money. I mean, why do most people work, many biologists work in cancer? Uh, work in cancer research because there's a lot of money there. It's an important problem, but I might not have ever gotten involved in it if there wasn't money. I might've gone and I was going to be a botanist when I, when I was a kid. That's what I wanted to do. Um, so having money available will bring people to bear. Now, another mistake that's often actually made, I think by the lay public about science is that people think that we're paid to do things. Just as you said, I get a research grant and luckily from the NIH there, they give you a fair amount of latitude. I will go my own way and I'll find something. I might've proposed something, but I'll end up somewhere entirely different by the end of the project. And that's how good science is done. You follow the, you follow the data, you follow the results. Um, and so that's what I'm hoping can be done here. I think the worst kind of thing that could be done with this subject area is to put it inside another company where they have a set plan of what it is they're going to do and the scientists either tell, do what the executives tell them to do or not. That isn't how anything will really get discovered. Put it, get it out into the public, get open minds thinking about it and then publishing on it and doing the right kind of work. That's how real progress will be made with this. Let's again, put our sort of philosophical hats on. Do you think the US government or some other government is in possession of something of extraterrestrial origin that is far more impressive than anything we've seen in the public? If I, I've not seen anything personally, but if I believe the people who I don't think can lie, yes. This is how does that make you feel in terms of the way government works, the way our human civilization works, that there might be things like that and we're not, they're not public. Is, is, is there a hopeful message for transparency that's possible? Like if you were, if you were, uh, in power and I'm not saying president because maybe the president is not the source of power here. Would you release this information in some way or form? Yes, if I were, I think it would, I think it's, I think it's something that can bring humanity together, right? I think that knowledge of this kind of thing to know that we are, you know, we are more alike than we are different in comparison to whatever this is, is, uh, is a positive thing for us. Um, and to know, you know, I don't necessarily care that the government has been hiding it. And I think, you know, people who've been talking about what we should give government officials or whatever amnesty, I think that's probably the right, the right answer. We don't, this isn't a time to look back and say, you did something wrong. You did whatever you did because that was the data you had available to you at the time and those, you had good reasons for doing it. Now, if your reasons were selfish, if your reasons where you wanted to do it because you wanted to monetize it yourself, uh, to the, to your benefit, but against that of others, then I think maybe there's something else that could be said, but you know, an opportunity to get all this information out. If I were in charge, I would, I would try to do it. Now I might be shown something though that says, there's a reason why you don't want to let anybody know this. Maybe you don't want to let anybody know this and maybe you don't want everybody have having access to unlimited, uh, energy because maybe you might turn it into a bomb or something that gives you hints that something like unlimited energy is possible, but you haven't figured it out yet. And if you make it public, maybe some of the other governments you have tensions with we'll figure it out first. Right. I mean, it's kind of an arms race going on, I think in all forms and it's, it makes me truly sad because, uh, it's obvious that, um, for example, the origins of the COVID virus, it's obvious to me that the Chinese government, whatever the origins are, is interested in not releasing information about it because it can only be bad for the Chinese government. And every government thinks like this, like every, actually this has been disappointment to me talking to PR folks at companies, like they're always nervous. They're always like conservative in the sense like, well, if we release more stuff, it can only be bad. And then an Elon Musk character comes along who tweets ridiculous memes and doesn't give a fuck. And I've been encouraging CEOs, I've been encouraging people to be transparent. And of course, government is national security is really like another level as human lives at stake. But let's start at the lighter case of just releasing some of the awesome insides of the tech, how, how the sausages made the technology and being transparent about it because it excites people. It uh, like you said, it, it connects people and inspires them. It's a good for the brand. It's good for everybody. I, I honestly think this kind of idea that people will steal the information and we use it against you is, um, is an idea that's not true in his idea of the 20th century. Like you said, some of the benefits of the social media, uh, our, our social world is that transparency is beneficial and I hope governments will learn that lesson. Of course, they're the, usually the last to learn such lessons. What do you make of Bob Lazar's story in terms of possession of aircraft? Do you believe him? I don't believe in the Bob Lazar story to be quite honest. I mean, I, uh, Jeremy Corbell has done a great job interviewing him and, uh, has done some, you know, beautiful, uh, documentaries. Um, I just don't, I, I don't know how to interpret it. And um, you know, and again, there's some of the people who I fraternize with think it's all rubbish. Uh, yeah, but he, maybe he's right, but I don't know. I mean, the, the problem is, and um, this is a little bit different about how I approach the whole area than a lot of others. I'm less interested in going over old paperwork and all these old histories of who said what, you know, the whole, he said, she said of the history of, of UFOs, I'm a scientist. I worked on the brain area because it's something I can collect data on. I can go back to the same individual, collect their MRI again and redo it. I can hand that MRI to somebody else. They can analyze it. I can get materials, I can analyze them. I can get some of these skeletons. I won't touch any skeletons ever again, but I can analyze it and somebody else can reproduce the data. Yeah. I mean, that's what I'm good at. And so, you know, I'm, I, I, I'm not going to go into the whole, I'm not a historian. Yeah, that's true. But there's a human side to it. I want, sometimes I think with these, because again, anomalous, rare events, some of the data is inextricably connected to humans, the observations, I mean, I hope in the future, you know, that, that, that sensory data will not be polluted by human subjectivity. But you know, that's still, that's still powerful data, even direct observations, like if you talk about pilots. And so it's an interesting question to me, whether Babasar is telling the truth, whether he believes he's telling the truth too, and what also, what impact his story and stories like his have on the willingness of governments to be transparent and so on. So you know, you have to credit his story for captivating the imagination of people and getting the conversation going. He's maintained his story for all these years with little to no change that I'm aware of. So but there's so many other people who are, let's say, experts in that story. Their gut, you know, you accumulate a set of sort of circumstantial evidence where your gut will say that somebody is not telling the truth. Yeah. You mentioned Avi Loeb, I forgot to ask you about Oumuamua. You know, because you've analyzed specimens here on Earth, what do you make of that one? And what do you make broadly of our efforts to look, look at rocks, essentially, or look at objects flying around in our solar system? Is that a valuable pursuit or maybe most of the stories can be, most of the fascinating things could be discovered here on Earth or on other nearby planets? Just going to Oumuamua, you know, I think Avi's insight is an interesting speculation, right? Like I was saying before, people can sometimes look at something and not see it for what it is. Somebody would just look at that and say, oh, it's an asteroid and dismiss it. There was something odd about the data that Avi picked up on and said, well, here's an alternative explanation that doesn't fit, that actually better fits the models than it just being a rock, you know. And to his credit, he just has ignored the critics because he believes the data is real and is using that then as a battering ram to go after other things. And I think that's, I think that's great. You know? Yeah. What, what is his main conclusion? Does he say it could be of alien extraterrestrial origin? Is that his? Well, that's one of the things. I mean, he, you know, he's explained how it could be a light sale. And a light sale is certainly within near human capabilities to make such a thing. I think Yuri Milner, he's a Russian billionaire. He's involved, I think, in a project to make light sales with laser, you know, to, to launch them with laser power, essentially, towards Alpha Centauri, right? So it's something that humans could make. I think Avi's proposal is perfectly within the realm of possibility. I mean, sadly, the thing is, you know, now nearly out of our solar system. Yes, I mean, to me, that's inspiring to do greater levels of data collection in our solar system, but also here on Earth. And it just seems like we should be constantly collecting, collecting data because the tools of software that we're developing get better and better at dealing with huge amounts of data. It's changing the nature of science, I mean, collect all of the data, right? Collect the data. I mean, I, I, the Galileo project asked me over the weekend to join and I did. So you know, I'm not a specialist in any of the stuff that they're doing. But you know, in looking at the list of people who are on there, there are really no biologists on there. So at, at some point, if my expertise is required for something. What's the goal and the vision of the Galileo project? Better talk to Avi, but my understanding and just actually looking at the, at the sort of the bylaws this morning, literally just got them, is number one, collect the data on UAP. And number two, collect data on local, potentially local technological artifacts. I need to look into this. This is fascinating. And Avi is heading the Galileo project. Yeah. Have you spoken to him? On this podcast? Yes. That was before, I believe it was before he was headed. Oh. Is this a new creation? Yeah. The Galileo project was, I think it's about six or seven months old now. Okay. You know. That's amazing. And he's getting a group of scientists together. Oh yeah. That's awesome. Actually, I am, I was looking at some of their stuff over the weekend. I'm shocked at the level of organization that they've already got put together. That's amazing. It looks like a moonshot project. I mean, I've been involved with a lot of NIH, large NIH projects, which involve a lot of people in coordination and they're putting it together. So you're extremely well published in a lot of the fields we began this conversation with. So you're a legit scientist, but yet you're keeping an open mind to a lot of ideas that maybe require you to take a leap outside of the conventional. So what advice would you give to young people today that are in high school or in college that are dreaming of having impact in science or maybe in whatever career path that goes outside of the conventional that really does something new? If you believe in something, you believe that an idea is valuable or you haven't approached something, don't let others shame you into not doing it. As I've said, shame is a societal control device to get other people to do what they want you to do rather than what you want to do. So shame sometimes is good to stop you from doing something unethical or wrong, but shame also is something that is circumscribing your environment. I've never let people who've told me, you shouldn't do that line of science, you should be ashamed of yourself for even thinking that, give me a break. Why is it wrong to ask questions about this area? What's wrong with asking the question? Frankly, you're the person who's wrong for trying to stop these questions. You're the person who's almost acting like a cultist. You basically have closed your mind to what the possibilities are, and if I'm not hurting anybody, and if it could lead to an advance, and if it's my time, why does it bother you? I had a very well known scientist once tell me that I was going to hurt my career talking about this. If anything, it's enhanced my career. I have a couple of questions on this. So first of all, just a small comment on that. I've realized that it feels like a lot of the progress in science is done by people pursuing an idea that another senior faculty would probably say, this is going to hurt your career. I think it's actually a pretty good indicator that there's something interesting when a senior wise person tells you this is going to hurt your career. I think that's just the one, as a small, if I were to give advice to young people, if somebody senior tells you this is going to hurt your career, think twice about taking their advice. Yeah. I mean, I think that's the primary thing. And the other, I tell my own students, I have a lab of about 20, 30 people and it's been that big since 1992. People come and go. It's not the data that falls in line that's so interesting. It's the spot off the graph that you want to understand. When something is way off the graph, that's the interesting thing because that's usually where discovery is. And the number of times that I've stopped people in my lab and said, wait a second, go back a few slides. What was that? And then it ended up being something interesting that made their careers, I could count on a few hands. Yeah. Get excited by the extraordinary that's outside of the thing that you've done in the past. Just on a personal psychological level, is there, I'm sure at Stanford, I'm sure in you exploring some of these ideas, there's pressure. How do you not give in to the pressure? How do you not give in to the people that push you away from these topics? What would you say is shame? I just point to my successes. I say, you're the ones who told me not to start companies all this time ago. And now you're the one coming to me for advice for how to start a company. But from the scientific area, it's you're wanting to take something off the table that might be an explanation. How is that the scientific method? I reverse shame them. So purely with reason through conversation, you're able to do that. So it doesn't feel, because to me it would just feel lonely. There's a community. There's a community of science, and when you're working on something that's outside a particular conventional way of thinking, it can be lonely. There's in the AI field, if you were working on neural networks in the 90s, it could be lonely. I have met some of the most fascinating people ever that had I stayed the conventional track, I would never have met. Truly brilliant people because of this. So it is for those worried about, well, should I step outside of my comfort zone? You're going to meet some really interesting people. And because I'm open about this area, I'll go and give a talk in Boston, Harvard or MIT. And at dinner, inevitably, this subject comes up. And inevitably somebody else at the table will admit both that they're interested or that they've seen something. And suddenly the whole tone of the conversation changes. It's kind of like there's safety in numbers and then, or I've had people come to me afterwards after dinner and say, Hey, I don't talk about this openly, but. So the number of scientists who know that there's something else going on is much larger than the scientific community would like to think. That's a really powerful one, which is, I don't talk about this openly, but here's what I believe. And you'd be surprised how many people speak like this and hold those beliefs. And I am optimistic about social media and a more connected world to reveal more and more, like us not to have these two personalities, we're like this public and private one. We've mentioned the big questions of the origins of the universe. What do you think is the meaning of this whole thing for us humans, our human existence here on earth, or just at the individual level of a human life? What Gary is the meaning of life. I think that what we're going through today with this realization, it's kind of like you've lived on an island your whole life and you've looked across the ocean and you've never imagined there was another island with anybody else on it. And then suddenly a ship with sails shows up. You don't understand it, but you realize that suddenly your world just got a lot bigger. I think we're in one of those moments right now that our world view, our galactic view is opening to something a little bit bigger. And not just that there might be somebody else, but that there's something else. And what it is, is yet to be understood. And the fact that it isn't understood to me is what's exciting because I can fill it with my dreams. And this discovery our world might is about to get a lot more humbling and a lot more fascinating once we look out and realize we were on an island all along. It makes us both smaller but larger at the same time to me. You know, I can look outside at the stars and think and imagine what else might be out there. And although I know that I will never see it all, it excites me to know that it's there. Well Gary, both to respect your time and also because at 12 I turned into a princess, let me just say thank you for doing everything you're doing as a great scientist, as a person willing to reject the conventional, and thank you for spending your extremely valuable time with me today. Thanks for talking. Thanks so much. It was great talking. Thanks for listening to this conversation with Gary Nolan. To support this podcast, please check out our sponsors in the description. And now let me leave you with some words from Stanislav Lem in Solaris. How do you expect to communicate with the ocean when we can't even understand one another? Thanks for listening and hope to see you next time. of what you might bump into. So obviously all of that planning requires access to all the senses. It requires access to your desires, memory, knowledge of where and what you want and desire to walk nearby. Like I used the example of if you're at a party, you wanna avoid that person, you like that person, the waiter is about to drop something. All without thinking, you maneuver. So that actually, all that planning is done in the basal ganglia. And it's actually now called the brain within the brain. It's a goal processing system. Subservient to executive function. So what we think we found there was not something which allows people to talk to UFOs. I mean, I think the UFO community took it a step too far. What I think we found was a form of higher functioning and processing. So what we then looked at, and this was the most fascinating part of it, we looked then at individuals in the families or those, let's say the index case individuals. And we found that it was actually in families. And more so, this is the most fascinating part. We've probably looked now at about 200 just random cases that you can download off of databases online. You don't see this higher connectivity. You only find it in what Kit Green would have called or has called higher functioning individuals. People who are, I mean, he called them savants. I don't have the means to, we haven't done the testing. But it turns out my family has it, right? We found it in me, my brother, my sister, my mother. We found it as well in other individuals, husband and wife pairs. So statistically, if you had a group of 20 individuals and you found two husband wife pairs, both of whom had it, and yet it's only found at about, we think, one in 200, one in 300 individuals. The fact that two individuals came together, two sets of individuals came together, both of whom had it, implied either a restricted breeding group or attraction. The reason why it seems to be in, let's say, so called experiencers or people who claim, if intuition is the ability to see something that other people don't, and I don't mean that in a paranormal sense, but being able to see something just in front of you that other people might just dismiss, well, maybe that's a function of a higher kind of intelligence to say, well, I'm not looking at an artifact. I'm not looking at something that I should just ignore. I'm seeing something and I recognize it for, not what it is, but that it is something different than what is normally found in my environment. Yeah, you know, I have a little bit of that. I seem to see the magic in a lot of moments. I have a deep, it's obviously, not obviously, but it seems to be chemical in nature that I just am excited about life. I love life. I love stupid things. It feels like I'm high a lot, on mushrooms or something like that, where you'd really appreciate that. So I'm able to detect something about the environment that maybe others don't, I don't know, but I seem to be over the top grateful to be alive for a lot of stupid reasons, and that's in there somewhere. I mean, it's kind of interesting because it really is true that our brains, the way we're brought up, but also the genetics enables us to see certain slices of the world, and some people are probably more receptive to anomalous information. They see the magic, the possibility in the novel thing as opposed to kind of finding the pattern of the common, of the regular. Some people are more, wait a minute, this is kind of weird. I mean, a lot of those people would probably become scientists too. Like, huh, there's this pattern happening over and over and over, and then something weird just happened, and then you get excited by that weirdness and start to pull the string and discover what is at the core of that weirdness. Perhaps, is that, maybe by way of question, how does the human perception system deal with anomalous information, do you think? Well, it first tries to classify it and get it out of the way. If it's not food, if it's not sex, right? If it's not in the way of my desires, or if it is in the way of my desires, then you focus on it. And so I think the question is how much spare processing power, how much CPU cycles do we spend on things that are not those core desires? What is the most kind of memorable, powerful UFO encounter report you ever heard? Just to you, on a personal level, like something that was really powerful. Well, I mentioned the Zimbabwe one. That's particularly interesting. And one that actually most people don't know about, but family driving down the highway, two little girls in the back, open glass topped car, and the little girls see a craft right over their car. This is in the middle of the day on a busy highway. The mother sees it. Nobody can, they look around, nobody else seems to see it. So the girls take out their camera, take a picture of it, and then they get home. They look at the picture. There's no craft, but there's a little object about 30 feet above their car or so, probably about three feet across, kind of star shaped. It's not the craft, but it's something else. Obviously there was something there. And so what were they seeing? Were they seeing a projection? Were they seeing, and why were only they seeing it? And the photograph was capturing something very different than what we're seeing, but they're still an object. Can you give a little bit of context? Is this from modern day? It's modern day. Oh yeah, they had a camera. I mean, they had a cell phone camera. And this is like a report provided. By the way, where is a central place to provide a report? Is this? Oh, there's a move on, but this isn't public. I've seen the picture. Oh, this is something you've directly interacted with. Yeah, yeah, I've seen the picture. So those moments like that, they captivate your mind. It's so different, and it doesn't fall into the standard story at all. But it also, but in another way, it's kind of a, it's a clear enunciation of this notion that when people see events, they don't all see the same thing. Now, we've heard this about traffic accidents. Different people will see the color of the car differently or the chain of events differently. And this tells you that memory isn't anywhere near what we think it is. But the issue around these so called UFO reports is that the same people will see a very different thing, almost as if whatever it is is projecting a, is projecting something into the mind rather than it being real, right? Rather than it being a real manifestation, material in front of you, it's actually almost some sort of an altered virtual reality that is imposed on you. I mean, I think the company Meta and all the virtual reality companies would love to have something like that, right? Where you don't have to actually wear something on your face to experience a virtual reality. What happens if you could just project it? Well, that's the fundamental question from an alien perspective. When you look at it, or as we humans look at ants, how does its perception system operate? So not only how does this thing's mind operate, how does the human mind operate, but how does their perception system operate so that we can stimulate the perception system properly to get them to think certain things. And so, that's a really important question. Humans think that the only way to communicate is in 3D or 4D space time, there's physical objects, or maybe you write things into some kind of language. But there could be just so much more richness in how you can communicate. And so, from an alien perspective, where somebody has much greater technological capabilities, you have to figure out how do I use the skills I have to stimulate the limited humans. Right, well, I mean, let's take the ants exam again as an example. Let's say that you wanted to make ants practical. You wanted to use them for something, right? You wanted to use them as a form of biological robot. Now, DARPA and other people have been trying to use insects for, turn them into biological robots. But if you wanted to, you would have to interact with their sense of smell, right? Their pheromone system that they use to interact with each other. So you would either create those molecules to talk to them, to make them do, I'm not saying talk to them as if they're intelligent, but talk to them to manipulate them in ways that you want. Or if you were advanced enough, you would use some sort of electromagnetic or other means to stimulate their neurons in ways that would accomplish the same goal as the pheromones, but by doing it in a sort of a telefactoring way. So let's say you wanted to telefactor with humans. You would interact with them. And this is, again, this is a technology which you could imagine possible. You could telefactor information into the sensory system of a human, right? But then each human is a little bit different. So either you know enough about them to tailor it to that individual, or you just basically take advantage of whatever the sensory net is that that individual has. So if you happen to be good at sound, or you happen to be a very visually inclined individual, then maybe the sensory information that you get that's most effective in terms of transmitting information would come through that portal. I think the aliens would need to figure out that humans value physical consistency. So we've discovered physics. So we want our perception to make sense. Maybe they don't, you know, that's not an obvious fact of perception, that you have to figure out what kind of things are humans used to observing in this particular environment of Earth, and how do we stimulate the perception system in a way that's not anomalous, or not too, it doesn't cross that threshold of just like, well, that's way too weird. So they have to, I mean, that's not obvious that that should be important. Maybe you wanna err on the side of anomaly, like lean into the weirdness. So communication is complicated. Well, that's why I always find this issue of people talking about the so called grays as interesting, because it is related to what you're saying. They're different enough, but they're not so different as to be scary, right? They're not venom dripping fangs, right? They're different enough, but it's also like they're what you could imagine us becoming in some distant future. So is that a purposeful representation? I don't know. I mean, I don't believe in the grays, for instance, but I believe that people think that they see it. So if we're talking about a communication strategy that says, you know, we're like you, but not the same as you, this might be a manifestation that you represent in terms of a communication strategy. What do you make of David's favorite sighting of the Tic Tac UFO, and other pilots who have seen these objects that seem to defy the laws of physics? Well, I think you have to take them at their word. Are they fascinating to you? Oh, absolutely. No, I know a lot of these people, right? So I know Lou Elizondo, Chris Mellon, the whole crowd I've been, I saw the videos about three weeks or so before they went public. I was at a bar with Lou overlooking the Pentagon in Crystal City, and they showed them to me, and my hair stood on end. And he said, this is coming out soon. And I know one of the guys on the inside who was the Naval Intelligence who had interviewed all of these pilots again before this came out. And it was hair raising to hear this, but also exciting that here's not just people's testimony, these are credible individuals. And if you've seen the 60 minute episode with some of the pilots, they have no monetary gain. If anything, they've got negative gain from coming out. But then you also have all of those simultaneous ship analysis from the USS Princeton and the radar analysis, et cetera. So at the end of the day, it's just data. It's not a conclusion. I'd be perfectly happy, honestly, perfectly happy if somebody showed that it was all a hoax. I can go back to my day job, right? That could be a hoax, but other things might not be. This is the point. This is why it's nice to remove some of the stigma about this topic because it's all just data and anomalous events are such that they're going to be rare in terms of how much data they represent. But we have to consider the full range of data to discover the things that actually represent something that's, if we pull at it, we'll discover something that's extraterrestrial or something deep about the phenomena on Earth that we don't yet understand. Right. Well, if it only stimulates people, for instance, to think, okay, well, what happens if we could move like that with momentumless movement? And it stimulates young individuals to go into the sciences to ask those questions. That to me is fascinating. I mean, after I've been openly talking about this in the last year, especially, I've had a number of students from top schools who aren't my students come to me and say, if I can help, let me. How can I help? I never had thought about this before, but you opened, you and others, not just you and others, have opened my mind to thinking about this matter. Yeah, that's why it's actually funny that Elon Musk doesn't think too much about this, these kinds of propulsion systems that could defy the laws of physics as we currently understand them. To me, it's a powerful way to think what is possible. It's inspiring, even if some of the data doesn't represent extraterrestrial vehicles. I think the observation itself, it's like something you mentioned, which is hypothesizing, imagining these things, considering the possibility of these things, I think opens up your mind in a way that ultimately can create the technology. First, you have to believe the technology is possible before you can create it. In my own lab, we always look for, as I've said before, what is inevitable, and saying inevitably this is the kind of data we need, but if we need that kind of data, the instrument we want doesn't exist. Okay, so I imagine the perfect instrument, I can't make it, and you back into something which is practical, and then you, in a sense, reverse engineer the future of what it is that you wanna make. And I've started and sold at least half a dozen or more companies using that basic premise. And so it was always something that didn't exist today, but we imagined what we wanted. And at the time, many people said it couldn't be done. I mean, for instance, all the gene therapy that's done today with retroviruses came from a group meeting in David Baltimore's lab. I was a postdoc with him, and one of the other postdocs wasn't able to make retroviruses in a way that he wanted to, and I realized I had a cell line that would allow us to make retroviruses in two days rather than two months. And so he and I then worked together to make that system, and now all gene therapy with retroviruses is done using this basic approach around the whole world, because something couldn't be done, and we wanted to do it better, and we imagined the future. And so that's, I think, what the whole UFO phenomenon is doing for people. It's like, well, let's imagine a future where these kinds of technologies are, but also let's imagine a future where we don't blow ourselves up, right? So if these things are there, they manage to not blow themselves up. So it means that at least one other civilization got past the inflection point. So if some of the encounters are actually representing alien civilizations visiting us, why do you think they're doing so? You suggested that perhaps it's the study understand their own past, right? What are some of the motivations, do you think? And again, from our perspective, us as humans, what motivations would we have when we approach other civilizations we might discover in the future? Well, I think one motivation might be to steer us away from the precipice, right? Or on the assumption that, even if we make it past the precipice, at least we're not a bunch of psychopaths running around. So maybe there's a little bit of motivation there to make sure that the neighbor that's growing up next to you is not unruly. But I mean, maybe it's sort of a moral imperative, like what we have with creating national parks where animals can continue to live out their lives in a natural way. I don't know. I mean, that would be, I mean, the problem is we're imagining from a anthropomorphic viewpoint what an alien might think. And as I've said before, alien means alien, right? I mean, not Hollywood aliens, but a whole different way of thinking and a whole different level of experience and let's say wisdom, hopefully, that we could only hope to understand. Now, but if we ever get out there, if we ever make it past our current problems, and even if we don't have faster than light travel, and even if we're only using ram scoops or light sails to get where we wanna go, and it takes us 10,000 years to get somewhere or to spread out, we might encounter such things. And are we just gonna stomp all over it like we did in colonial South America or Africa or all the rest on our current path, likely? And so what are we gonna learn? Well, we're getting better and better at understanding what is life. And I think we're getting better and better at being careful, not to step on it when we see it. And this is one of the nice things about talking about UFOs is it expands the Overton window. It expands our understanding of what possibly could be life. It gets us to think. It gets the scientific community to think. When we go to Mars, when we go to these different moons that possibly have life, we're not looking at legged organisms. We're looking at some kind of complexity that arises in resistance to the natural world. And there's a lot of interesting. I like that, resistance to the natural world, yeah. So somehow there's a rebellious process, complex system going on here. And I don't know the many ways it could take form. There's a sense for aliens that as the technology develops, they take form more and more as information, as something that can influence the space of ideas, of the processing of data itself. So I just, this idea of embodiment that we humans so admire, physically visible, perceivable embodiment may be a very inefficient thing, right? If you think just about your area, AI, we're trying to make smaller and smaller and smaller circuitry that is basically closer and closer to the physics of how the universe operates, right? Right down at the level of, I mean, quantum computers are basically right down about quantum information storage. So fast forward 10,000, 100,000 years, maybe somebody found a way to embody AI directly into the physics of the universe, right? And it doesn't require a physical manifestation. It just sits in space time. It's just a locally ordered space. We're just locally ordered space time, right? You know, I mean, but maybe they just, they found a way to embody it there. They probably have to get really good at not, you know, trampling on the ants. The better your technology gets, the easier it is to accidentally like, oops, just destroy these simpleton biological systems. We constantly think about whatever these things might be. We think that they are some sort of a unified force. Well, maybe they're not unified. Maybe they are as disparate as you and I are. And maybe what keeps them from stomping all over the ants is each other, right? That they are in a self tension to prevent one or more of them from running amok. Oh, yeah. I mean, that's kind of the anarchy of nations that we have on earth. So there's always going to be this. There's a hierarchy. This hierarchy that's formed of greater and greater intelligences. And they're all probably also wondering, wait, what's bigger than me? Exactly. That's what I always wonder is that maybe that they're, what keeps them in line is something that is beyond them. Like what created the universe. I mean, that's probably a question that bothers them too. What about the communication task itself? How hard do you think it is for aliens to communicate with humans? So is this something you think about about this barrier of communication between biological systems and something else? How difficult is it to find a common language? Well, I think if you're smart enough or technologically enabled enough, it's relatively straightforward. Now, whether your concepts can ever be dumbed down to us, that might be hard. I mean. Again, talking to the ants. Talking to the ants. I mean, they don't. On Instagram. So. You want to look good in this picture. Let me explain to you. Let me explain to you why. Yeah. So that's the essential problem of, you know, perhaps they realize who it is that they're talking to. And they say, rather than muddy the picture, we're only going to give them limited information. Yeah. Right? And yeah, maybe we could sit down, like you and I, and have a conversation. But then they would make assumptions. The humans would then make assumptions about us that aren't true. Because we're not humans, right? So let's stay at arm's length. Let's just let them know that we're here, right? And here's the limited amount of communication. Again, this notion that if you give somebody everything, they'll get lazy. And, you know, if they've been around as long as they have, they've seen every kind of thing that can go wrong. And so they know as much as they might want to step in, that that would be a wrong thing. Yeah, you have to also understand the amount of wisdom they carry. Yeah. You know, and so it's very easy as well for religions to, I don't want to get into a whole religious conversation, but it's very easy for, you could see how religions could call them angels or devils or what have you. Because, again, if you're trying to fit it into a framework of cultural understanding, the first thing you reach for is God. And so when you look at what these things are, and again, with the angels and the devils, in a similar sort of way, their communication is limited. They just kind of give little, what's the oracle of Delphi? They kind of give these Delphic pronouncements, and then it's up to you to figure out what it is that they really mean. Yeah. Steven Greer claimed that a skeleton discovered in Atacama region of Chile might be an alien. You reached out to him and took on the task of proving or disproving that with the rigor of science. The result is a paper titled Whole Genome Sequencing of Atacama Skeleton Shows Novel Mutations Linked with Dysplasia. Can you tell this full story? Well, the story was, as you put it right there, correct. Reached out, got a sample of the body, did the DNA sequencing, then worked with a team of two other Stanford scientists and Roche sequencing group, Roche Diagnostics, and probably a total team of about 11 or so people. And as is standard in these kinds of things, the professors actually don't do the work. The students do the work and figured out the answer. And then we helped them put together the story. And the story was simply that it was human, 100%. I went into it thinking it was originally a monkey of some sort. I got kind of excited a few months into the process, thinking, well, what happens if it is an alien, right? Can you describe some of the characteristics of the skeleton that makes it unique and interesting? Primarily, it had dysmorphias of the brain. And so the first thing I did actually, when I got pictures of it, I took it to a local expert at Stanford and he was on the paper. And he was the world expert in pediatric bone dysmorphias. He literally wrote the book on this, because that's what you do. You go to an expert when it's outside of your field of interest. And he said, well, I haven't seen this particular collection of mutations before or this physiology before, but here's what I think it might be. And he said, but based on the size of the thing and the bone density, it would appear to be like six or seven years old. Now, again, that's the thing where I think the lay public doesn't understand or takes a speculation like that and turns it into a fact. No one ever said that it was that age. We only said that the bones made it look like it was that age, but then we went back and looked for, we went back and looked for genetic explanations of why things might look the way they did. And if you, again, read the paper is very carefully caveated to say that these mutations might result in this. But what we did find was an unexpectedly large number of mutations associated with bone growth in this individual. And it was just a bad roll of the dice, right? You roll the dice enough times with enough people born every year and someone will roll the wrong dice all at once. So the sad part about it was individuals in the UFO community who wanted to think that there was some sort of conspiracy around it, right? That somebody had somehow convinced all of my students to lie. I mean, come on, you know, I would lose my job, first of all, and they would all be in trouble forever. Yeah, but also it's just projecting malevolence onto people that doesn't, I don't think exists in normal populace and especially doesn't exist in the scientific community. The kind of people that go into science, I mean, this is what bothers me with the current distrust of science, is they might be naive, they might not, especially in modern science, look at the big picture, philosophical, ethical questions, all that kind of stuff, but ultimately they're people with integrity and just a deep curiosity for the discovery of cool little things. And there's no malevolence, broadly speaking, in the scientific community. So, I mean, there's a bigger story here, which is, you know, there's a hunger in the populace to discover something anomalous, something new. And, you know, science has to be both open to the anomalous, but also to reject the anomalous when the data doesn't support it. What do you make of that, you know, walking that line for you? Because you're dealing with UFO encounters, you're dealing with the anomalous. Well, people have said, let's go back to the Atacama case that I was debunking it. Well, debunking is a loaded term. Sort of assumes that you were going in purposefully to prove something is wrong. I wasn't, I was just going in to collect the data. And, you know, I showed that this one was human. There was another skull that somebody had at one point. It was called the star child. They called it the star child skull. I said, you know, I looked at it. I looked at the DNA sequencing that they had done. I said, this is human. End of story. The people who owned the thing at the time disagreed with me, and then eventually another group came in and proved that I was right. And it's not about debunking. It's about getting the more spectacular and hyped cases off the table. I mean, the reason I got interested in it is because somebody was hyping it. And not because I wanted to disprove it, but because I just wanted to know. And thus, get it off the table, because it's usually the most extravagant things that are most likely to be wrong. Somewhere in the rubble will be something interesting. And so that's what you do. You get the dross off the table. And then somewhere in the data will be something worth real inquiry. And that, if you inquire deeply enough, will be extravagant as well. Yes, exactly. And that's what actually excites scientists is to, I mean, you want, with the rigor of science, to actually reveal the extravagant. And so look at CRISPR as probably the most perfect example of that. These weird sequences in bacterial genomes, all arrayed one after the other with these strange sequences around them, but when you looked at the sequences, they looked like viruses. And so how did they get there? And lo and behold, after a lot of effort and work, well, a couple of Nobel Prizes went out the door. But these strange things ended up having extraordinarily extravagant possibilities. You've also looked at UFO materials. You are in possession of UFO materials yourself. Claimed UFO materials, alleged. Alleged UFO materials, that's right. So what's another term? Weird materials that don't seem to have a story. They have a story that doesn't seem to be of natural origins, but it's not, you know, there's a process to proving that. And that process may take decades, if not centuries, because you have to keep pulling at the string and discover where they could possibly come from. But anyway, you're in a possession of some materials of this kind. Can you describe some of them and maybe also talk to the process of how you investigate them, how do you analyze them? Right, so let's say that there's two classes of materials that I've been given by people. And they're not given by the government or anything, just given people who've collected them, and there's a reasonable chain of evidence associated with them that you believe is not just a pebble somebody picked up off a road. There are almost always things that people have claimed have either been dropped off as like some sort of a leftover material, molten metals, or they are from an object that was released from this or that kind of exploded. They're almost always metals. I have some couple of things that might be biological that are interesting that I haven't really spent a lot of time on yet. When you look at a metal, you basically, well, OK, what are the elements in it? And what's it made of? And so there's pretty standard approaches to doing that. Most of them involve a technology called mass spectrometry, and there's probably about five or six different kinds of mass spectrometry that you could bring to bear on answering it. And they either tell you, depending upon the limit of the resolution of the instrument, they either tell you the elements that are there, or they tell you the isotopes that are there. And you're interested not just in knowing whether something is there or not, you're interested in knowing whether there are the amounts of it, and in the case of elements, how many different isotopes are there. And that's kind of where, in some of these cases, it gets interesting. Because in at least one of the materials, as we first studied it, the isotope ratios of, in this case, it was magnesium, are way off normal. And I just don't know why. It doesn't prove anything. All it proves is that it was probably accomplished by some kind of an industrial process. Whether it's the result of a process, and this is sort of the leftover, or whether it was made that way for a particular purpose, I don't know. All I know is that it was engineered. That's it. But then the question is, sort of you go one step deeper, why would you engineer it? Right. Why engineer it, and what does engineered means? There's all kinds of, it could be a byproduct, it could be the main result of an engineering process, it would be a small part of the engineering process that is the main part. Well, so the ratios of isotopes for any given element are basically the result of stellar processes. Supernova blew up sometime several billion years ago. That became a cloud. Those atoms coalesced gravitationally to form another sun, and a ring that became a rocky planet. And the ratios of the isotopes were determined at the time of that explosion. And so everything in the local solar system is more or less of that ratio, depending upon certain gravitational difference. But by fragments of a percent, not whole tens of percent difference. So what do humans use isotopes for? Mostly to blow stuff up. I mean, the vast majority of the isotopes that have been made in the per pound or ton are things like certain ratios of plutonium and uranium to blow stuff up. We don't make or engineer isotopes, which today is relatively easy to do, but it's still expensive. For any other reason, apart from, let's say, anti cancer,
