@@BotvsBotsjoin Navy, open up your world view. I quit high school before senior year at 17. Navy taught me computers & electronics. GI bill paid my college, now a poor millionaire. Go for it!
Oh, I was 3 months old when my father was killed in war. I grew up poor but to dumb to know it. 1st job paper boy age 8. Had money ever since.
Don’t be a lazy ass. Just do it!
🤡, UNSUBBED
What an intelligent LADY! Great guest choice! IMO
I appreciate the complexity and depth that these interviews go into. My favorites are the ones that ponder the origins of life, consciousness, and reality. Lex, thank you for your journey to understanding the human condition!
Your Welcome, Lex. ❤
Lex is just the best of the best at the art of the interview.
@17aggareaud - It’s all in books- it has been for ages- don’t you read books ? She obviously does - then hey Presto she’s ‘intelligent’?
@@vivtodd2473 while you read the books, she writes them. Hope that helps!
Gyatt dam tell me more lady
I love her approach to the podcast, the way she lays out thoughts and how open she is, and how deep she’s willing to get into it. Love for Lex who’s so curious about many things and shares it with us in this way!
Agreed 💯❤🎉
In contrast of the ones who want to stick to a narrative track. A real sign of a balance of EQ and IQ
I personally appreciate her ethics as well. I've seen her speak often and she's careful not to infer meaning. I think sometimes this is misinterpreted as evasion when actually she's just leaving room for autonomous thought.
Like, you know, like .... giggle, giggle, I passed by thesis defense because no one had the guts to ask me anything from Halliday and Resnick, and the university was required to matriculate a couple of female children.
This woman is absolutely perfect for what she is doing in her field. I love this third talk SO much!
Third*
Yep, moving physics to the women's studies department will help humanity understand the basic processes governing the universe. Or, at least we'll feel better when we laugh at the children.
Round 3. lol
Could not agree more. Absolutely fantastic interview and discussion.
She’s igniting my desire to go back to school and learn science in a more formal way. I think about this stuff daily but I have very basic understandings and keep pausing the video to research terms you use, and concepts I am not familiar with. this woman is really hitting me in a personal place with her mind and how she thinks. I am mesmerized with the subject matter and her profound thoughts and understanding. I’m in awe of such intelligence really.
And you too Lex, brilliant, you have such an amazing understanding of so many subjects and I love the summaries of your guests answers you give as a response they really aid my understanding of the content. You push my boundaries with your podcast and I think you ask the best questions.
Go off queen
You having guests like this is why I love your podcast! Keep up the good work Lex
I love… love how Lex intertwined his experiences with his perception of the universe with us.
YESS! AMAZING GUEST! so happy to see Sara back on the podcast!
Lex! I don’t know what it is, but I totally appreciate seeing how you interact with your guests. You treat people with astonishment and they appreciate it, and give you their best ideas. I absolutely adore every concept you guys are discussing here. Such an example of the gems that exist in our understanding of the universe. Thank you both. ✌️❤️
Sara speaks so simply. I can understand Sara so simply. Thank you both!
That sounds sarcastic to me 😂
youre just another nutter online
@@EK-fy5yy no not at all
I'm autistic. Every thing I write reads like that. Sorry!
I like that you ask the easy questions like why does anything exists 😂
What happened before the big bang? Where did the matter come from? Give them one miracle they'll explain the rest 😅
Someone clicked the start-simulation button
The question is: why can there not be nothing? Or is this an answer?
Why do we question?
Exist?
I love the way she talks!! I love the way she thinks so deeply and complexly, but paints it so clearly with her words. It’s freakin beautiful!!😭😭
I hate the way she talks . Every answer she gives she goes in loops without actually answering the dam question.
@@nataliemanzo34I agree. Her thoughts never land on a fact or explain a meaningful insight. Reminds me of Terrence Howard a bit. Lex needs to nail her down and explore her responses to find the core. “material properties”.
I agree with you as well,she is definitely on the right track about asking the right questions before giving a answer to question you haven’t even asked or even understand the question. I don’t know what the trolls above are going on about they said nothing about anything
@@panthersoulI don’t know what you were watching she answered every question and stated her position on every topic comprehensively. Maybe you should rewatch it you probably will come to have a different opinion. If not your entitled to your opinion . Peace sincerely M. Sylvester
Brilliant people are often misunderstood by those less brilliant. She is brilliant.
Thanks Lex for having Sarah on again. Love your mind and thinking processes, Sarah. The stepping out of a definition that no longer explains what we are learning and discovering about our shared existence is so key to humanity opening up. We hold on too long to accepted "laws" and it slows us down. The ever-expanding visualization process is beautiful.
Yes, Sara Walker is awesome!! So glad you invited her back…her thinking is Mind-blowing!!
Date number 3!
Meh her definition of life got really touchy Feely and bereft of any actual useful connotation. Language isn't life...
I agree! This is my first time hearing her. She's super interesting and out of the box.
She seems very disillusioned with everybody else's points of view, though.
Her thinking makes money 😂😂😂
@@Chris-es3wf she crazy talks out both sides of her mouth and uses slight of hand /miss direction,confusion,,marginalizing ,the circles she a predator.Spiritual type the type you run to the hills and dont look back,everything backwards for her lol.And DONT GET ME wrong some of the greatest scientist were/are open minded.But HOW SHE MIXES TRUTHS LMAO in absolute across the board,cause confusion.Its mind control subversion without you knows demoralization vexing.Question ppl reality at ever turn lmao,while talking in f/ing circle ,spinning her lies.
oh my gosh Sara I love your brain, your narrative is so connected to everything, material, spiritual!! Thank you for this refreshing insight into the world, thank you Lex for bringing Sara
she declared qualia to be physical system and i agree.
She relies too much on "feelings". She said so herself. It's also why she contradicted herself about 5 times... bc her theories are feelings and not anything defensible.
I'm not as intelligent and intellectual as some of you guys but can appreciate a moment like yours intelligent and insighfull.
Can she succ?
Its eastern mind meets western mind in a lot of ways. (‘see: Alan watts)
Chris you need shrooms to understand
Some don’t
I have to watch this in bits..... As my brain starts melting 😂... Give it a few hours rest and continue. So amazing and articulate. Such a beautiful mind❤
This, to me, must have been the most amazing interview on this channel! It's extremely rare for me to listen to a person and agree 99% and want to listen again and again. Thanks so much Lex!
What was the 1% you did not agree with?
@@andanssas I would probably say something different on consciousness, but it doesn't matter. What a genius, I am just happier now that I know this girl exists!
Lex- those visual effects while hanging out with your friends in the forest after the ayahuasca ceremony that you described are known to us seasoned gulpers of psychedelics as "tracers".
Peace, love, and respect, to you, and for all you do.
Trails*
@@HWM636 I agree, my friends and I saw them on LSD many times.
Totally fascinating! I love Sara Walker's explanation on the physics of life, yet, she's leaving the door open for future interpretation. "Life is a balance between holding on and letting go." - Rumi ❤ Thank you both for this extraordinary conversation! ❤
Sara Walker rules! Always a fascinating conversation when she is on the pod. Her work feels an awful lot like she is proving Buddhism with physics.
I love this channel for the opportunity to listen to brilliant people talking about subjects that I, alone, would not be able to develop a clearer understanding. Lex is great interviwer because he always ask questions pertinent to a particular moment of the explanation, in an unobstrusive way.
In relation to the guest, I found her amazing. Besides being charismatic, her approach to the question of the origin of life is the most reasonable and logic, yet mind blowing, I ever heard. Never imagined it would feel good to think about me as a 4 billion years cristal of accumulated living information 😊
Lex is a very fortunate person not only to be able to talk to such brilliant people, but also to have the capacity and generosity to share those exceptional conversations with us. Thank you.
Sara and Lee really are my favourite scientists. Although I am based in Glasgow doing VR, their insight and such strong foundations in their ideas I found incredibly important to my research philosophy during my recent PhD. Cannot wait to listen to this.
@lexfridman I love her. What an amazing human being. Brian Cox & Lex Fridman is what I've been hoping for.
this
Professor Brian Cox is a “lemon.”
Yesss Brian Cox! 100//
@@NerzhinaHow the hell is he a lemon? He's an unbelievably gifted guy
Cox would be cool but think about Zizek!
I love when you invite physicists. My favourite conversations to listen to ❤
Its so awesome to see recurring guests and how they seem to adapt and evolve with the podcast just like Lex himself! She is getting so much better at flowing complex ideas under Lex's style of interviewing
Now these are the interviews I'm here for!
One of our favorite guests on Lex. Awesome, let's go!
This woman is absolutely fascinating and massively intelligent. I fully enjoyed this interview.
I listened to this while sleeping and had some CRAZY vivid dreams!
If I listen to something while sleeping, I dream about getting a virus on my phone and not being able to turn it off
@@jameswelch5636lmao that’s shitty man lol. Sorry prolly isn’t funny but yeah. Usually I’ll dream about whatever I’m listening to.
Yes, we all are waiting for the footages of ayahuasca, episode after another one.
I am not. Why are drugs so interesting here?
No Need
You're not understanding what it is. You're misinterpreting it as "tripping" or seeing crazy things. There is another side that is not connected to our human body and it is a gateway to seeing it. Unlike distortion of reality. It's not going crazy. It's becoming more clear minded more aware of what's going on. But then seeing this reality is just a facade.
Drugs affect your brain negatively.@@andreassciascia5745
@@andreassciascia5745 not manmade
Better not. Let Lex enjoy his experiences.
Usually I reject all videos on youtube that are 70+, but there's something about Sara Walker that makes me keep listening, almost impossible to stop. And I look very forward to her book in early August.
Loved this discussion! The conversation on assembly, and subsequently the whole “more possible ways to be dead than alive” topic & word meanings was fascinating!
I cannot remember how I ever got through life without this podcast!
I high key am obsessed with Sara walker and how she thinks about/articulates the most complex and befuddling topics. Thanks for having her on again. One of my favorite scientists and guests of yours!
Thanks, Lex! It was fantastic to see Sara on the show again. Both she and Lee Cronin are outstanding guests.
It's incredible insight, that combinatorial space of 'anything' could be driven by whatever the life mechanism is
20 mins in when shes talking about abstract forms of life and different ways of thinking... i always remember lex saying the aliens could be all around us and we could be staring them in the face... this is exactly what i imagined on how ''alien'' life could be.. even life itself on earth from the first cell to the very last could be a giant 4D hyperbolic fractal sponge slipping through our 3D world, lasting billions of years and and this is just what it looks like from our perspective
Im kind of overwhelmed by the feeling of the sublime. This is infinitely interesting.

"What senses do we lack that we cannot see or hear another world all around us?" -Frank Herbert
Plenty of things ''could be'', but it seems rather pointless to me to point to one of the endless 'options' and marvel at it. What does ''a giant 4D hyperbolic fractal sponge slipping through our 3D world'' mean?
Lex my fellow human brother, I hope you are happy as you read this comment. I can tell you have moments of genuine admiration and love for people as they do something as simple as mowing their lawn, or drinking a cup of coffee while looking out the window at little bird doing bird things. I know you have these moments! That's why I wish for your happiness from time to time.
When she talks about us being 'big' in space, i can't help but to remember the video from Veritasium on the p-adic numbers. While the possibility space for assembly grows exponentially, it can't be infinite
How can everyone not love Lex.
It is baffling, isn’t it? I can safely say I platonically love him lol
Sara just explained why.
he’s boring and seems a bit autistic
Him furthering the fascist (or totalitarian) cause?
Like in love? For real.
Idk how she makes that yellow sports jacket work but she does 😂
Maybe, but I’m getting really strong Tweety Bird vibes lol 🤣!!
@lostinthedesert-hp4bw really? I'm thinking Kill Bill lmao
Blonde people shouldn't wear yellow, even the fake ones... that goes for all Whities tbh, pale goes bad with yellow w/o looking gash.
But one can talk oneself out of that, just as putting physics into Twitter, timeline of things we see but can not explain... so no, still does not work gal, ur white, no yellow jackets for you. Brrrr!
number 2 most compelling podcast ive seen behind "The Amazon Guy"
Sara is brilliant and I like how Lex just lets her speak and lay down her theories and findings! She's as much a philosopher as she is a physicist.
I’m in Organic Chem right now and we just went over Chirality. It was a super interesting topic when she was discussing it. Knowing the definitions of Achiral and Chiral centers/ atoms along w R & S configurations really added to the subject.
The existence of uniform chirality throughout the Earth is strong evidence that life occurred only once on this planet.
She thinks on a level well above what most of us do. She sees something directly that most of us sort of intuit. And she’s knows she can’t explain it to us with spoken or written words.
If this comment gets 10k likes Lex will ask Sara out on a date.
Waiting for the roast 😂😂😂. Like why?
If I’m gonna give a Like then I want a Lex/Mearsheimer date
I thought this was sarah jay at first. I need help ..
He needs 10k likes to ask her out🤔 Get on it lex!!! The chemistry between these two is amazing
Sara can do better
please interview Lemon AI's CEO 🤩
Sarah, here I am unloading from my truck a mass of soil (and giant soup of life forms wriggling digging decomposing) and compost that I collected on the side of a mountain road at the base of sloughing cinder cone on the big island Hawaii and I'm finding it difficult to continue to muster the"mana"to keep shoveling because the sound of your voice is so soothing. It's not just a sound though it's also what's spewing from your brain! Come visit! Aloha!
Lex, how can we thank you enough for your continued excellent content! Keep it up!
George Carlin had a good perspective on life: “People say life begins at conception, I say life began about a billion years ago and it’s a continuous process.”
Agreed! But mammalian life itself propagates by insemination.
And that process had a precursor. It didn't just start that way.
@das_it_mane yup she sums up basic processes required for creation of life. Great video.
@@victorgarcia4399 Life invented sex to fuel its propagation.
These podcasts are the great ones, Sara has a really interesting unique brain, also in the podcast with Lee, the back and forth. Those are the people that are really interesting to listen to since they explore ideas concepts that weren't there before. Very stimulating for the brain.
This is not one to listen to casually lol
Will have to come back to it - this is the type of thought that occupies my most creative/fascinating thought processes...i love it.
You will get nothing out of this: it's like astrophysicians talking about black holes theories. Grab your Bible.
Loved this conversation! It's always interesting to hear Sara's perspectives, and Lex is great interviewer. Thank you!
I love the point about needing a recursive definition to include everything including itself.
Wait until she finds out this is all a simulation
Bruh 😂😂😂
Seriously, your comment made me giggle to myself .
What a fantastic episode.
I could listen to this all day long; I love it!!!!
Sara is a fascinating and thought provoking guest and Lex is a fantastic interviewer.
Love to you both ❤❤
Lisa Simpson as a human adult
I thought she was April O'Neil
Lol so spot on
Her voice 😂😂!
Thanks for sharing this great conversation with us Lex. Your friends and guest are always extraordinary people… as are you dear friend.
OK, this is a GOOD ONE Mr. Fridman
Sara Imari Walker is such an interesting person. Her 3 ways with Lex and Lee are absolutely fascinating as well as this cast. It's also great that more and more theoretic and frontier science is starting to break the shackles of academic orthodoxy and speak openly about how much we don't know, rather than the mustering and corralling of knowledge that now looks so typically last century.
This was an amazing conversation. And it meant so much to me to hear the discussions on language itself. It’s a topic I’ve struggle to find someone else with whom to discuss but also a topic that has dominated much of my thinking in the last 6 years of my life. Thank you!
Same, I always tell ppl I’m attempting to explain something really complex to (weather it’s how I’m feeling or something else) that I wish I could just plug my brain into theirs and send the info over (feelings, thoughts, how I got to the way I’m thinking/feeling, what I’m seeing in my imagination, etc) because often times words just can’t explain certain complex concepts, emotions, etc.
Yay! Sara is back 😊🎉
This is the best podcast episode I've listened to EVER. Thank you for interviewing this brilliant researcher.
I’ll think I’ll have to listen to this interview 15 times
That was an amazing podcast. I can't remember the last time my brain was tickled like that. Thank you Lex and thank you Sara
I love that Rogan has Terrance on, and says "what if", and Lex has Sara Walker on and says "what if". Very different directions.
Sara isn't a fool.
Awesome episode! I think about this sort of thing all the time. Written a lot about it too. Information holds the key, I theorize
This is one of Lex's top three episodes ever. Fantastic discussion.
I clicked on this podcast as another one in the line but quickly it became my favorite strings of words I have heard in years. It took me places Neuromancer did ;) She was speaking about my internal states, drawing with words suspended like sunlight in the crystal of current culture. I mean it was David Foster Wallace like experience. It is like in Contact with Judy. They should have sent a poet. They should have sent Sara ;)
I have this mental tradition to remember 5 podcast/reviews/videos/radio programme that were an absolute top in any year. This goes to my number one. It is so fitting that she became vocal in your podcast at the 40 anniversary of Neuromancer. She is the new embodiment of what Gibson did with language then.Gave us the new language game.
I'm borderline in love with this woman...my goodness she talks the way my Brain analyzes and and relays things to me
I knew it was time to refresh
When we have Biden and Trump as presidential candidates life cannot possibly be deterministic unless we go 4+ years in the future, look back and then describe the why or how
Be great if this conversation had subtitles!
Can you spot four little icons in the top right hand side of your screen - tap the little square box that says ‘cc’. Subtitles will appear.
Sara walker talks are always the best
I must report that I just experienced goose bumps seeing another podcast with Sara Walker.
Absolutely brilliant! I'm writing a book focusing on the universal importance of mycelia! Thank you for sharing these existentially important conversations!!!
one of my favorites man i've watched this three times and only slept once :) Sarah is incredible what an enormous brain
This is one of the best podcast conversations I’ve heard in a long time. LEX! You gotta have her back more often! This was so interesting 🎉❤
This is one of the few theoretical physicists that I appreciate today. She is self deprecating enough to realize a lot of theoretical physicists are bullshit artists. She is lovely and very smart. She has an excellent sense of humor and dedication to honesty.
thank you for this Lex .. this was a really good one .. the structure thing sounds like the ruliad
I've been waiting for a follow-up conversation with Dr. Walker!!
Love listening to Sara on the road. Looking forward to the book and her return.
Sara is awesome!
I could listen to Sara talk about stuff that's way over my head all day! 😍
Damn this starts at 100 and just keeps going! One of my favorite episodes already, only 20 minutes in.
LOVE the new Hair Sara!!!!! Always a pleasure hearing you speak
love the hair!
Watching this and listening to them, and trying to find out what on earth they are saying, feels like I might be the one that is on Ayahuasca.
Wow, what a great interview. Without a doubt I'm getting Sara's book.
Wish I had time-stamped it, but there is a moment when they are talking about the excitement and dread which results from the acknowledgement of our vastness, the near-endless possibilities we are confronted with in life. It made me think of that great quote from Kierkegaard: "Anxiety is the dizziness of freedom." And yet somehow, listening to this amazing conversation has stilled the ever-present anxiety that haunts my soul. Thank you, Sara. Thank you, Lex. This was easily one of the most thought-provoking discussions I have heard in quite some time :-)
Well done, my man! Possibly the most interesting conversation I’ve heard in a long time. Salute.
Спасибо что снимаешь такие реально крутые подкасты, украинцы в германии тебя много смотрят. Спасибо за такой контент,который крайне редко вообще в огромном нашем мире делают и публикуют!!!
one of my favorite guest in Lex's podcast, love to listen to Lee Cronin as well, they articulate their ideas so well, both are great science communicators . at around 43:44 , she made me laugh so hard, she mentioned about we like to get traumatized/being afraid, we like to learn more about the world and once we do, it traumatized us, coming to understand new ideas which you never understood before is a thrilling experience, totally agreed and could relate to this.
Expressing yourself through fashion may serve the same purpose as expressing yourself in words. It allows you to dive deeper into the structure of what it is you are expressing.
Sara Walker and Joscha Bach in dialogue - that would probably blow one of my fuses. i love the way - like Joscha Bach - Sara Walker pushes me to one side of myself. BOOM !
Very similar "almost crazy" kinda genius.
16:20 Sara drops her 1st definition of life … 👏 “life is the physics of how the universe decides what gets to exist” … more follow
The universe of the gaps. :)
Which will create the best memory of self reflection. We are the Universe looking in the mirror.
We are the world observing itself through us. (Federico Faggin)
That's not a actual definition, that is a metaphor.
Again I don’t normally comment on appearance but Lex is gorgeous with his facial hair!! Beautiful 💜
Thanks Lex 🎉❤ always grateful for your channel much love from Belgium 💖
Finally some mentioning about the ayahuasca experience.....30:30 and 1:32:45 :)
Trippytrip
Re: his description of his head turn and visualisation of the past moments of the person he was with, following a head injury I had this for quite a while - not just with people but with everything. Turning my head quickly resulted in a view of the world like a blurred photo with several momentary past versions of the room / person. It was interesting but disorientating.😂 I wouldn’t want to consume anything that induced it again 🤣. Loved this episode with Sara Walker.
Crazy a 3 hour podcast can have 42 views before the first min after it’s posted lol
New ways of thinking about things is the way. Sarah is on the right path to gain great insight.
