I really enjoyed this conversation with Sean. Here's the high-level outline: 0:00 - Introduction 2:21 - Understanding the universe and the mind 4:03 - Universe as an information processing system 9:34 - Simulation theory thought experiment 14:33 - Intelligent life in the observable universe 15:34 - Defining intelligent life 19:34 - SpaceX and space exploration 21:05 - Origin of life 29:40 - Interdisciplinary science and conversation

I can never get tired of listening to Sean

Huge fan of Sean’s. His book “something deeply hidden” is one of my all time favorites. His brain works on a completely different frequency . The way he grasps concepts, breaks them down and explains them while making it very easy to comprehend makes him invaluable to the scientific community. He just gets it. I’m so glad he’s been on podcasts like Fridmans and rogans, I have them on repeat often when I’m on a psychedelic adventure

Let's appreciate how lucky we are to be able to watch brilliant people , like Sean Carroll , talk about science... This wasn't really possible before KZfaq.

Please have another one. This was awesome

The ways this conversation flows is special. Amazing!!!

Omg when you said the audio recording died, my heart sank because I thought that some one had passed...

One of the best non-mathematical conversations I have ever heard. There is nothing wrong with including mathematics in a discussion, but when you do not, it doesn't mean you must dumb down the conversation completely. You did a really good job of balancing both ideas. Seeing the math in action is powerful, but by no means the only method to share ideas. Thank you for this!

Sean Caroll on Lex Fridman... maaaan, Christmas came early

Spending the next portion of my life trying to learn more and understand intellect, and intellectual thought. Really appreciate all you do, and many of your personal views. You make it easier to understand the conversation. For that, I thwnk you greatly.

Excellent episode. Asks (and answered) the most interesting questions other podcasts would have ignored, be too afraid to ask, or have the creativity to compose.

Lex! _This_ is the one you lose audio on? 🤨

Wow, you can see Sean getting wiser, more open to stuff he is not sure or even opposed to. That's very heartening... cool!

Definitely the singular guest I was most eagerly awaiting to join Lex. To think this episode in particular was cut short by technical difficulties is indeed something I'd rather attribute to the paranormal than describe my disappointment...damn those phantoms.

Thank you so much. It is such a pleasure to watch and listen to your conversations with all these interesting people.

Fantastic discussion. Such a pity about the audio loss. Thank you for your work.

Keep up the great podcast! Totally inspiring and broadens my view!

Lex you guys were gonna solve the mysteries of the world then the audio cut out. Thank you for the podcast, and what you do. It brings regular people closer to scientists that we may never have access to. Have a blessed year.

Lex, thanks so much for doing these interviews and sharing it with us.

We need to hear the rest! One of the most entertaining conversations, please repeat Lex

here from JRE - very glad to hear you started your own channel. this is the first video i chose to watch and i love it 5min in. youtube wise you're doing it right. post video conversations in long form and make your own sharable cuts a long with the high-level outlines. I really enjoy it man great work. i'm a fan. i work as a software engineer dealing primarily with corporate solutions servicing and breaking into AI in the way of machine learning - preemptive tickets being opened before a server goes down and transferring to a failover and automating the logging, investigation and startup - its wild to think and explain where all of this should and can go. i find myself explaining to clients the interconnections and how triggers are set as well as how the machine learning evolves over time to better suit their eco-system and i see their eyes glaze over and awkwardly try to stop talking really before i even get started .. .needless to say your conversations here allow for that outlet and mind to run. just started my own company too refining and standardizing the implementation above - cheers man

Спасибо за эти подкасты, продолжай в том же духе👍

What predictions arise from the universe expanding and entangling qubits vs the universe birthing them? Also, please redo this convo asap, Sean is a truth bomb dispenser. All his answers were deep yet digestible. Amazing talk and I'm glad I at least got this glimpse of it. Thank you.

I listen to Sean’s podcast love it

Asked Sean over on his channel if he could get you on about a week ago, and now I find him here on yours. Absolutely fantastic! Shame about the audio, but listening to my two favorite smartypants, if only for 34 minutes, works just fine by me. Keep up the good work Lex!

I think your assessment of consciousness is closer to the truth than most people want to admit. Very interessting conversation

Sean in this type of setting is the man, just amazing, so much clarity he gives over interdisciplinary issues. I have never heard any better in any other context. My brain feels so good after listening to him. Lex is also great!

I think I've only ever commented on a tiny handful of KZfaq videos... But this was such a wonderful, brilliant, fascinating conversation. Many thanks to both of you.

I love how “normal” Lex is. Just casually twirling in his chair while Sean Discusses the mystery of the universe. 😂😂

Keep up the good work Lex! Although I may not be as accomplished as you, I identify with your story. I too came to this country at 13 from a country with a shitty political situation (vzla) and have a career in software engineering. I am extremely interested in all the topics you put forth!

Thanks for the podcast.

Could listen to both these guys talk for days. Thank you for doing this!

What a shame, that the rest of this conversation went missing :(. This was still super interesting. Thanks for making this podcast

Sean Carroll is in my top 10 most interesting humans alive. His mathematical? Co-ordinate explanation of the space-time cone changed my understanding of the fields of influence around me and brought new awareness of the universe and how it functions. Using this virtual knowledge with practice I've begun to observe certain events in everyday spacetime as collapses of the wave function. The many examples are when coincidences occur that are supranatural, intuiting a future event that is realized, recognizing a particular vibe or energy when meeting new people that is corroborated by future behaviour, observing a discrete set of data collect in a manner that solves a nagging problem or obstacle, recognizing "strange attractors" as the vortex of a seemingly chaotic pattern or fractal, recognizing in dreams metaphors of events, relationships, red flags etc.

Sean Carroll is an excellent physicist, I enjoy his output.

Is it just me, or does Sean Carroll feel like an actualized Simpsons character?

Sean Carroll is so articulate.

Thanks for posting this. Subscribed!

centuries ago conversations like this must have occurred at churches and temples... metaphysics. it's wonderful.

Great channel and nice work! Appreciate it!

These guys makes me happy!

Two great minds right here!

Mind. Blown. Well done.

Nice work 👍. Love Sean

Sean” I would argue that” Carroll

I love this podcast

I'm sure you're sick of hearing it: always have an independent secondary recording of the audio. Most people would be happy to hear the audio even if the video failed. I've listened to ;podcasts where they had to fall back on an iphone recording. Still a lot better than it being completely lost.

This was excellent. Too bad about the recording. I hope you have him on again soon.

Great episode! Normally I'm kind of a Lex critic, but the view on consciousness at 25:25 was a really great way of putting it.

While this guy is awesome very humble and very very intelligent love listening to him

nice talk, great issues for the discussion.thanks! i think we are on the eve of the next revolution in physics for understanding life on much better level because the TOE to which we are close enough right now has to include life (as the obserber of the observable universe) into its consideration. surely, understanding of life, as a very specific thing/physical process in the physical universe, is the leading edge of modern fundamental science (of physics and maths for the first turn).

Great Podcast

He is a great educator

i just wish this was longer!

He is basically telling everyone that he's not human this whole time "Your species" "You've never met me, how do u know I'm human. May come out later I'm not"

great discussion

These were great questions, I really appreciate how on point you are. Sean Carroll is definitely among the first 100 people I would let on the ark in a drought scenario. when/where can we get a peek at the notes of the missing footage?

This is a good one. I always enjoy listening to Carroll, but had not heard him talk about most of these topics. I tend to agree with him more on life in the universe, consciousness, and the origin of life more than with most of the experts working in these fields. Aside, I would not call Pinker optimistic. Listen carefully, he recommends a way forward based on progress through history (which may make him sound like an optimist), but he is not reticent about how far we are from the ideal and what can go wrong.

Enjoying this! Aside: No the sound engineer did not die during this interview. Thankfully! (I misunderstood at first -- until you said these accidents happen. 😆)

Ah, I think it would be fun to extract the content of sean speech just from the video footage. Should we use GANs for that...??

If I ever ouch my knee, Lex... Your voice would soothe me😊 "it's gonna be aaaaaall right, buddy"

I like that idea of consciousness: something you convince something of by programming it never to disbelieve it.

The podcast cut short is an example of the awareness (I call it a wave function collapse example) I was talking about and the coincidence that it occured during the podcast when SC was the guest.

You da best Lex

The universe that we see is mostly ancient....light just travels too slowly......most of the universe that we see is more than a billion years old....if life out there started 100 million years ago.....light from it has not reached earth yet.

great podcast. Also, i believe the real science experts(physicist, data scientist, neuroscientist, AI scientists, cosmologists, etc) who are doing some actual science should reach out to other fields. There are lot of us who are interested and curious about science but not professionals. Science can expand faster with more people getting involved. u doing a great work. love it.

I just watched the podcast with Jeff Hawkins and find his description of how he thinks brains work (frames of reference) to be similar to how Sean Carroll explains (around 9:00) how degrees of freedom become entangled . It has echos of the same mechanisms. As you add more frames of reference or degrees of freedom entropy of the system gets larger over time but the system functions the same, but better? . Time is also key component of each description.

You could use a lip Reading neural net on the video from the part which has missing audio and correct the transcript manually. Then you could upload the video with subtitles

A major obstacle to the simulation argument is simultaneousness. Any two events cannot occupy the same time frame if executed by one processor. And yet, we know that this is possible in the reality we live in. To simulate down to Planck scale, the simulating computer would need a dedicated processor for every Planck unit.

Wouldn't it be great if we created a conscious computer but we can't figure out how we did it? I'm hoping it goes down that way. Great interview Lex! I'm a big fan of professor Carroll!

Dang too bad the audio is gone. Its so short. Just do another one :)

Subscribed !

Somehow Sean Carrol wearing tshirt with a gecko from self organising cellular automata makes me even more excited about the future..

He gives me the vibe of Robert California

I definitely think some of the implications of quantum mechanics are interesting in the context of if we live in a simulation or not. Firstly, the idea that our laws of physics suggest the Planck length to be the shortest distance scale seems similar to the way computer code necessitates a discrete building block to build any structure in a simulation. Secondly, the measurement problem and the idea of being uncertain of everything until observing it.

I was wondering why this episode was so short relative to your others. I thought maybe you could only get a hold of a little bit of Sean's time. Oh, well. Shit happens haha. It was obviously a good choice to upload what was recorded; it's gold. Good to see there's another, longer episode, too.

Such a shame that the rest of this conversation was lost because the beginning was so interesting. I experience lots of productive disagreement with both Sean (on simulated world) and Lex (on consciousness).

you are the master of eye contact

Can you tell us what topics were covered in the missing segment?

S.C. looks like he's getting younger.

learned a lot from this man. more human😍 and not robot😎

To cap it all, these wisdom titan s should have a wisdom of round table lasting a day or two ( just to be in line with the legendary scale ) exchange. The line up.. Richard Dawkins, David Suzuki, Tyson, Angela Merkel and others. Just a humble wishful thinking. Heartfelt Thanks . From HK

I appreciate the conversation. But I hope for more positivity’s

At very small (and large distances) in a simulation you naturally get a quantum foam like effect due to floating point precision errors. The way games get around this is by moving the entire universe around the avatar, who never moves from the origin. Precision is therefore always high.

I like to listen to people way smarter than I have conversations like this.

Kicking back.. closing my eyes and listening to Alan Alda explain to Lex his version of the universe.. lol

Love the black suit and tie. Very MIB ;)

Omg this is it, no bs scientist, happy to see

The biggest impasse to advancing technology to the point of extending our lives for thousands of years is not knowledge, it is large companies that will do everything in their power to quash it so that people still need their products to stay alive.

Around 9:10 Lex: ‘whadda you think about the bing bang’

14:02 what about higher dimensions? Is 3+1 dimensions not an incredibly low resolution?

Sad we missed so much

I would like to hear his ideas on the diehold foundation

He was denied tenure at the University of Chicago. Now he's a professor at Caltech. Do read his blog on tenure.

There for a minute I thought sure he was going to ask "Sean, where do your ideas come from?"

Sean's got that just-bailed-out-of-jail look going.

think a better question is, is the world a program (not a computer), it can either be a running in a purpose built computer, or running in a naturally occurring construct (in the parent world)

Lex is one of the Men in Black 🕶️

Nikola (Singularity) should bring Lex

If space expands then it's relative counterpart, "time" contracts. Wouldn't this limit degrees of freedom in the same relative fashion? Also, what do we predict happens at the intermolecular level or even the quantum level when the space between them expands, and thus alterring their physical interactions? I would predict ever increasing entropy! That could be relative too!
