[Copied] Hey lex, don't know where to get in to contact the best -- But I am River Jackson. I work on Quora and I am 18, I study theoretical physics and was hoping to get in contact to see if I could share some of my work on logic/universe/psychology with you. I do not need to record anything but would like to engage in a discussion and see if we can arrange something. You [I believe for the most part] would not regret conversation and I would love to have a word with you on some science topics - Timely [AKA, RJ]
Lex you’re the only podcaster I know that can keep up with such intelligent conversations, ask brilliant questions, and even rebuke some of it. I sincerely enjoy the entirety of each casting. Thank you!
Sean Caroll, Brian Greene and Steve Wolfram have good podcasts. I think Steven is my favourite but Brian is extremely sharp also. They're able to ask much more insightful questions but they're only accessible to people who are following physics and have prerequisite math knowledge. There's a great interview between Andy and Steve, but Wolfram gets too excited and basically just describes his theory to Andy. Andy is a great mathematical physicist. Very sharp man
If you knew a bit more it would be abundantly clear Lex has no clue what he’s talking about. One of his first statements is “so there’s no objective truth” … the other guy nearly gives up. He just moves past the idiocy. Unbelievable dimwit remark from Lex
I studied political science and history in undergrad. I teach social studies to kids. I have no background in science. Yet listening to Lex's podcasts have blown me away. THIS was a great one.
Great guest, really has a knack for increasing the laymen's understanding of concepts we've heard before but didnt really get. Hope you have Andrew back soon.
“We didn’t prove this?” (? sic) “I wish so, but I don’t think so.” “We don’t really know where we’re going.” “We don’t really have a clue.” “I haven’t solved anything, but I’ve said enough that you’re interviewing me.” Good gig.
I am so impressed at Lex’s intelligence. He was able to keep up with a really deep conversation outside of his own field. It was clear that he made himself familiar with his guest’s research. He bothered to at least read enough to ask interesting questions. I was unfamiliar with most of the topics, yet, I was interested to the end. Thanks!
Pretty sure that smiling is just duping delight. Looking at the comments its apparent that this "theoretical physisist" sumhow has ALOT of people duped. How do smart people not know when they are being told this made up poppycock, which is what theories are. Lex seems like a hell of a guy, but its scary that people can be so gullible & smart at once.

My gosh, such an amazing episode! I've watched so many of these brilliant podcasts and this one is definitely one of my favourites. The friendliness and liveliness of this whole interaction are next level.
This CD has three separate relaxation/meditation sessions on it th-cam.com/users/postUgkxzpa8CIfZcihW4Z0F_ja0QF3W9KIatrsq guided by a very pleasant and direct male voice. Unlike so many other products of its type, this CD does not have bad synthesizer music, does not feature a phony or affected style of narration, and does not make any bogus claims to be subliminal or to re-train the brain or any of that balderdash. What you get is 1. a guided meditation for getting into a pleasantly relaxed state of body awareness while taking a stroll (superb for those easing back into a fitness routine slowly after an illness or injury) 2. A nice long breath-awareness relaxation session that if followed diligently can put you into very deep states of full-body relaxation and mental calmness, and 3. a buddhist-inspired meditation session designed to help you develop and maintain feelings of loving kindness toward not just yourself and your friends, but toward people you don't even like. The CD makes no claims to be designed for advanced meditators or for buddhists or hindus/yoga practitioners looking for very deep and esoteric stuff. It is geared more toward the average person who just wants to develop the habit of relaxation and stress relief through natural, healthy means. him, if you happen to be reading this, keep up the good work fella, and I love your accent. I would also like to note that I have never fallen asleep while listening to this product. I would like to kindly suggest to the reviewer who said this CD makes him fall asleep, that he might want to get checked to see if he has a sleep disorder, or if he is simply not setting aside ample time for restful sleep at night. A healthy person getting adequate rest at night should be able to go into deep states of mental relaxation without dozing off, if not all the time, then most of the time.
I’ve watched soooo many of your podcasts and I thank you! This one is food for thought …for a long , long, time:) Tysm for keeping my curiosity alive and kicking! It’s such a beautiful world 🌎 ❤
I still feel cynical about it. But I like the way he said it’s a stepping stone. I don’t like how he deflected when asked to describe the holographic plate. Then at the end the description of the two mirrors in the department store hit on it. We need conversations like these.
@@PhilR870 My impression was that he also feels that way but views it as an imprecise tool that may be helpful in estimating what happens beyond an event horizon. I think it's interesting to think of quantum physics, relativity, string theory, etc. as a set of tools to be used in different situations - even if some are more precise and testable than others. ;) Of course quantum physics and relativity are confirmed every day, whereas string theory seemingly cannot be. But if the mathematics helps with guessing at what's happening inside a black hole, that is intriguing. But then, that's not proven either. LOL
“We didn’t prove this?” (? sic) “I wish so, but I don’t think so.” “We don’t really know where we’re going.” “We don’t really have a clue.” “I haven’t solved anything, but I’ve said enough that you’re interviewing me.” Good gig.
Hi Lex, Your podcast is one of the must interesting to watch, you are an extraordinary human being. Thank you for what you do. Would be great if you can add Spanish subtitles to the videos.
Thanks so much Lex for interviewing Andrew. I follow his work on Celestial Holography, even though I am not good at math. He expresses things in a way I can understand, which I really appreciate. 💛
Thanks Autism101, going to look up Celestial Holography.😊. I’ve struggled with quantum theory all my life and now Andrew Strominger makes it easy for me to understand too! Lex you make everything accessible and great back and forth, learn a lot from your discussions. Appreciate the work❤
There is a problematic thing about your view: I always show my students that they don't really understand the physics of a problem until they have solved the equations of that problem mathematically. When you think you understand the physics without the mathematical rendering, you are fooling yourself. It always falls short, sometimes more, sometimes less.
@@TheBaluchiterium There are levels of understanding and mine would be superficial and incomplete at best. I don't see how praising Andrew's effort to make difficult concepts accessible to people qualifies as me saying I understand all the underlying physics by watching a TH-cam video.
@@Autism101 You are totally right. I think my comment was aimed more at a notion that is growing inside the physics community, i.e., that it is essential to understand the physics without being able to actually do the math and the theory behind it. I should have to elaborate much more to make this crystal clear. Some things, especially in relativity and quantum mechanics, you can't understand at all without the math, because they are so far from our evolved "understanding" of things that only a mathematical rendering gives an acceptable answer. Or, as colleague Lawrence Krauss puts it, "every time I show a picture I have to lie a little. Only the mathematical version is the really correct one." Spot on. This is a real problem when communicating physics to the outside.
Lex thanks especially for this one , don't know how I've not come across this wonderful guy since I follow so many Physicists. He's just incredibly articulate although at my layman's level I'm going to have to watch this 3 times over and take notes .... so beautifully explained on a subject which is sometimes impossible to explain
I absolutely loved you comment that the speed of light is slow. I always thought it was fast. But you’re absolutely correct light speed is very slow compared to the scale of the universe. It had the professor stumped. Good one. Love these discussions. I’m on a long drive for work. These are perfect.
Even compared to the scale of the world. There's a couple applications I support in my day job where if you're more than a couple thousand miles away, it's just not going to work very well, if at all. It can take large fractions of a second for your signal to move down the fiber and back, even discounting delays introduced by the routers and switches along the way.
Mr. Strominger, many thanks for sharing your knowledge, thoughts and wisdom. Sincerely a great conversation that I found enlightening, profound and using a language that described our actual theoretical understanding clearly. Much appreciated 👋🏽👋🏽👋🏽
I didn’t know the Interviewed but I found his comments so interesting and the ideas so well developed that I stayed listening until the very end. At some point I decided to look for some information about him just to realizes that was Professor Andrew Strominger and his admirable curriculum. It was a very rewarding time. Thanks
Upon watching this I will claim to my esteem friends and families that I am expert of black holes and quantum theory in attempts to increase my social prowess. Thank you very much
16:27 he didn't assert the non-existence of objective truth, he simply asserted our lack of direct access to it. Approximation implies the existence of an underlying truth being approximated. He has in effect implicitly suggested that an underlying objective truth does exist.
Interviews with intellects is where you shine. Must have been nice being complimented at the end,"...great conversation...I can't believe you're able to discuss at this level so many topics". These are the interviews of yours I really enjoy.
INFINITE NUMBER OF COPIES OF URSELF HE IS SUCH A DUMMY QM AND SR WILL NEVER BE UNIFIED THEYRE LYING THRU THEIR DIRTY STINKING MATERIELISTIC NIHILISTIC ATOMISTIC TEETH
i've watched countless theoretical physics videos and discussions... I have a degree in philosophy of mind and studied AI at Duke (had a guest lecture of my 10 student class from Daniel Dennett which was a huge highlight for me!), big questions around conciousness that Lex brought up. This was undergrad level so I am only aware of the bottom 10% of most fundamental concepts. I have always been extremely envious of theoretical physicists because of the incredible gifts they have for mathematics and the technical complexities needed to advance the most complex concepts humans have ever created... concepts which defy all our intuition. All that to say... this is one of the most fantastic discussions I've consumed. It dives heavily enough beyond the basic facts we all know and have heard about quantum mechanics, black holes, curvature of spacetime, etc... that it gives someone like myself at 40 at least a reminder of what it was like to want to think hard about these topics, take the challenge of trying to understand a little more fully ideas that are very hard to wrap your mind around.... and to get real joy out of it. Most content I've seen is either frustratingly regurgitated basic concepts to get the view from the 19 yr old college freshman smoking pot... or (as I've seen on Lex's podcast some... sorry Lex) the far too technical discussions. Sometimes those technical discussions are just legitimate academic interactions that aren't really intended to be consumed in any useful way by someone who is not an expert in the field... that's completely fine... but sometimes the discussions are intended for a wider audience but the expert can't be bothered to unpack complex concepts or just has an air of arrogance (Weinstein... though I am fascinated by him). Strominger sits right on the perfect balance for the audience... he won't spend too much time trying to explain concepts which cannot be understood without the rare expertise he possesses. But he paints a larger picture and gets to the point of what the advancements may mean. Kudos for this, I have spent 4 hours watching this 2.3 hour podcast because I will go back to better understand a statement or section more fully. Thank you for stimulating this once eager mind
Intending on adding relevant info to what was said in the lecture - How to measure the error/distance of a theory from the absolute theory or from a previously existing theory?! I feel the lecture require a talk about the system by which you compose theories. Which is based on an intention-management system. Therefor I suggest attaching an error value on a theory, derived from the errors coming from using the theory along a certain intention. Giving us, a spectrum-tree of [error per intention], for the whole theory. Which will make it easier for us to choose the theory, once we know what we want to achieve, by ordering the theories by error on the known intention.
I don't really like her. She's a very gifted educator and has tons of charisma, but to me, she seems to be very obtuse when it comes to new ideas. Oftentimes dismissing things without delving deep into them. She's too eager to criticize or debunk anything unconventional, in a field where unconventional things were proven to be right over and over again. As an experimentalist, she's great, but when it comes to theoretical physics, we need people that think outside of the box, that are able to break the boundaries of what we already know. Those people will always be mostly wrong, but on rare occasions, they are right, and this pushes things forwards. Sabine is not really debunking anything, she just doesn't agree with anything outside of things we already know, and to me at least, she does not seem to be willing to push things further. Also, on more that one occasion she admitted being very shallow and not wanting to thoroughly dive into in trying to understand and verify a theory, before "debunking" it. She's definitely smart, can explain complex concepts in an intuitive manner and has her personal style. It's just that I can't see her as productive, when it comes to theoretical physics.
Since I read Hawking's book in the 90s, I have never gave up my attempt to understand physics and the matters he discussed. As an attorney my math and science education was not extensive, although computerized legal research in the early 80s required an understanding of algebra in developing queries. I wish I would have had math and science teachers who had not killed my early interests. I think my insatiable curiosity is the greatest gift in my life. Thank you for moving me further along the path to understanding. I deeply appreciate your videos.
Ending with a Heisenberg quote after a discussion about what is scientifically possible and what responsibilities scientists bear for what is done with their discoveries is perfect. Thank you.
It was a beautiful thing, a precious moment in time, to witness the admiration you have for each other and your work respectively. Magic and easily the cherry atop the icing of another well-baked interview.
I told my parents once that it's boring when everything is easy . They looked like I had 2 heads . Im glad I heard dr. strominger say that . Challenges are exciting when you are confident . ❤ from 🇨🇦 , thank you lex
After watching The White Lotus series, specifically the scene at the winery where the topic of mimetic desire is discussed, I have become fascinated with the concept of Mimetic Desire and currently reading the book Wanting: The Power of Mimetic Desire in Everyday Life by Luke Burgis. It’s amazing how mimetic desire can influence human behaviour both consciously and subconsciously for good and bad. Thought I would share this with the hope that a conversation with Luke on you podcast would be very insightful given your history, knowledge and passions.
Every time I listen to your podcasts I feel like the only fool in the room and thats good because it means I have something good to learn and listen to. You are an inspiration to me Lex and everytime you invite someone to your podcast I cannot wait to consume the information provided. Thank you!!!
Lex You should do a podcast where you interview chat GPT, and let it give it’s responses verbally. That should be fun. You would get a lot of correct answers and you would get a lot of very weird replies. I’m sure you could fit that into a two hour show!
You could even use a Podcasts like this one, just by cutting in your questions and let the chat bot reply. That would be interesting to see how different or similar it is to the replies that you got from Andrew Strominger!
I have been watching scientific talks for 3 years and I am very proud to say I understand most of the physics theories that are out there and I am starting to get into the details now . Don’t give up it’s rewarding as hell
2:08:30 Lex, is there anyone in academia who doesn't think there's life with ways like our own observable by us? I don't think in any of your interviews, anyone has even remotely erred towards that position, no?
Wow omg I had no idea! How long have you been keeping this secret? Does the media know, I've not seen anything on the news yet, Have you had the Nobel Prize phone call yet? I did hear a small group of people are thinking of starting a religion to worship you, give it a few months and you could be more popular as god! Unless you are god, omg I repent I repent please save me! I can die happy and fulfilled now, thankyou my Lord 🙏😇
If we are all scientists, why isn’t everybody happy and the ecosystem in balance? Why are we planning to move humanity to Mars to escape earth’s destruction? Nobody ís planing to destroy Earth… Except for…..? If you can answer that simple question….You might even be a scientist
Could the phrase “entropy always increases over time in an open system” be understood as “the total number of small units of space time always increases in an open system”? IE: quantum fluctuations are due to the cosmological constant as small units of space time spontaneously appear in our universe over time. Maybe there is a limit of space time curvature that above which new units of space time could not happen? This is why we don’t see expansion of gravitationally bound systems but the universe overall is? This is why it’s so hard to describe flat space time?
I liked how Professor did not dumb down things and kept the level of explanation that I did not understand fully everything, but this is better than simplifications, which are plenty. Definitely a great podcast! Thank you, Lex, and best of luck to Prof. Strominger.
I've watched the first 10 or so minutes and I felt that he dumbed things down a lot, like he has no idea Lex's usual audience. I'm glad that it will get better later on. Thanks for the comment, it motivated me to get past the beginning.
"The information contained in an English sentence or computer software does not derive from the chemistry of the ink or the physics of magnetism, but from a source extrinsic to physics and chemistry altogether. Indeed, in both cases, the message transcends the properties of the medium. The information in DNA also transcends the properties of its material medium." Stephen C. Meyer
Is there a good reason why we can't assume spacetime is made of gravitons, then let gravitons be the building blocks of wavefunctions. And finally, we can control gravitons as they are the entanglement between two entangled photons. If we do it this way, we can create a quantum gravity theory and then perform experiments on it. Why are you making it harder than it is?
Let’s nominate Friedberg to be the Chief Moderating Officer. Loved this episode’s pace, discussion and vibe. I think it comes from each of the hosts to speak their view without interruption.
Very interesting. Thanks for sharing your ideas about the responsibility of AI/ML researchers and his response to your question about weapons. Certainly the issues of AI military uses and the scientists role in weapons have some ethical parallels though the rapid development of machine capabilities is challenging our ability to imagine the potential consequences. Though I loved the physics of this piece, the bit at the end is also important.
I always think of Les too as Andrew said at the end...it is just amazing that he can discuss things at the level of his guests on so many varied topics. Kudos, Lex and many, many thanks~!!
Is there any way that because we are particles or gathering of particles near black holes that the connection that we have to blame black holes for subatomic forces Like the strong force connection Between the proton and the electrons could this be achieved in thes presser, could that be where these massive forces are stored/made Like quantum clustering or something?
I have a question. If nothing can exceed the speed of light, yet, something is basically sucking (for lack of better word) light from escaping. Meaning, what happens to the light? Is it just turned into slow light, which is what? Does it pull those photons backwards? But not faster than the speed of light itself? How does it capture the photon, unable go up to the speed of light? How does that work?
Light can't go faster than it already is. However, it's not fast enough to reach the escape velocities required to fight the gravitational pull of the black hole.
I met Andrew today at Cambridge university. He did a talk on black holes for the Andrew chamblin memorial lecture. Very interesting guy and gave great insights into string theory and information theory in relation to black holes especially when he was asked questions.
Actually, the escape velocity from the Moon is not 7.0 km/s as Strominger states, but only 2.38 km/s, which makes sense - the Moon has only 1/6 the mass of the Earth, which has an escape velocity of 11.2 km/s. I am dismayed that the audience listening to this podcast have not picked up on this...
We have to pose our questions in ways that are not self contradicting. Information is a human concept. It requires an observer to both determine and measure its value. By the definition we've given it, a black hole is a region of spacetime that we cannot observe, so there is no way to determine whether what we call information exists in a place that we can't observe.

Thanks Autism101, going to look up Celestial Holography.😊. I’ve struggled with quantum theory all my life and now Andrew Strominger makes it easy for me to understand too! Lex you make everything accessible and great back and forth, learn a lot from your discussions. Appreciate the work❤
There is a problematic thing about your view: I always show my students that they don't really understand the physics of a problem until they have solved the equations of that problem mathematically. When you think you understand the physics without the mathematical rendering, you are fooling yourself. It always falls short, sometimes more, sometimes less.
@@TheBaluchiterium There are levels of understanding and mine would be superficial and incomplete at best. I don't see how praising Andrew's effort to make difficult concepts accessible to people qualifies as me saying I understand all the underlying physics by watching a TH-cam video.
@@Autism101 You are totally right.
I think my comment was aimed more at a notion that is growing inside the physics community, i.e., that it is essential to understand the physics without being able to actually do the math and the theory behind it. I should have to elaborate much more to make this crystal clear. Some things, especially in relativity and quantum mechanics, you can't understand at all without the math, because they are so far from our evolved "understanding" of things that only a mathematical rendering gives an acceptable answer. Or, as colleague Lawrence Krauss puts it, "every time I show a picture I have to lie a little. Only the mathematical version is the really correct one." Spot on.
This is a real problem when communicating physics to the outside.
My power is out right now, so I am watching this on UPS. Yay! Great stuff Lex and Andrew.
Mind blown!! Always appreciate your conversations sir! Thanks for doing what you do.
Lex thanks especially for this one , don't know how I've not come across this wonderful guy since I follow so many Physicists. He's just incredibly articulate although at my layman's level I'm going to have to watch this 3 times over and take notes .... so beautifully explained on a subject which is sometimes impossible to explain
He has been on some world science festival episodes with Brian Green. One episode about string theory and black holes is really good.
Thank you Lex and Andrew what an amazing 2hrs. Your a rare genuine person with a good heart never change and please continue these interviews Lex.
I absolutely loved you comment that the speed of light is slow.
I always thought it was fast. But you’re absolutely correct light speed is very slow compared to the scale of the universe. It had the professor stumped.
Good one. Love these discussions. I’m on a long drive for work. These are perfect.
Even compared to the scale of the world. There's a couple applications I support in my day job where if you're more than a couple thousand miles away, it's just not going to work very well, if at all. It can take large fractions of a second for your signal to move down the fiber and back, even discounting delays introduced by the routers and switches along the way.
Amazing conversation, Lex you are delivering some greatness to us, every day people, thank you!
Lex, fantastic thoughtful interview that took proper time in a world of swirling bits of journalism
Mr. Strominger, many thanks for sharing your knowledge, thoughts and wisdom.
Sincerely a great conversation that I found enlightening, profound and using a language that described our actual theoretical understanding clearly.
Much appreciated
👋🏽👋🏽👋🏽
I don't like hearing people discuss about physics because I don't like the subject but I'll listen to you Lex because you make things interesting
Amazing podcast. I was engaged throughout the whole episode. Im kinda blown out of the water by how fast 2hrs went by.
Well, is good to know, how to work a black hole.
I feel asleep lol
The best part of having a new guest is no more clips of the last one
This is the first person I've heard explain black holes so simply
This is like watching Jason Bateman talk physics.
💯🤣
I didn’t know the Interviewed but I found his comments so interesting and the ideas so well developed that I stayed listening until the very end. At some point I decided to look for some information about him just to realizes that was Professor Andrew Strominger and his admirable curriculum. It was a very rewarding time. Thanks
Upon watching this I will claim to my esteem friends and families that I am expert of black holes and quantum theory in attempts to increase my social prowess. Thank you very much
16:27 he didn't assert the non-existence of objective truth, he simply asserted our lack of direct access to it. Approximation implies the existence of an underlying truth being approximated. He has in effect implicitly suggested that an underlying objective truth does exist.
andrew was very very engaging and i really really enjoyed this episode
Interviews with intellects is where you shine. Must have been nice being complimented at the end,"...great conversation...I can't believe you're able to discuss at this level so many topics". These are the interviews of yours I really enjoy.
Lex every podcast is a home run. You keep me sane during horrible monotonous periods of work.
Please find a new job that you are passionate about. You only live once. 🙏🏻
@@IntuitiveIQ facts!!!!
This is absolutely brilliant, I have literally no amount of thanks that I can express by watching this. Literally, and honestly, thank you Lex!
INFINITE NUMBER OF COPIES OF URSELF HE IS SUCH A DUMMY QM AND SR WILL NEVER BE UNIFIED THEYRE LYING THRU THEIR DIRTY STINKING MATERIELISTIC NIHILISTIC ATOMISTIC TEETH
What does "Literally, thank you" actually mean. Would not "thank you" suffice?
What an brilliant conversation. Thanks Lex!
These are the best interviews around! Thanks
what a beautiful conversation 😍 loved every minute
Lex is 100% on point with his questions an Andrew Strominger is so well rounded with knowlege
My two favorite podcasters together!! Truly a treat. Thank you
Wait, this nice fella does podcasts as well?
These are the best pods keep getting these guys on
A humble human being with a great talent and ability to explain complex concepts to the average people
i've watched countless theoretical physics videos and discussions... I have a degree in philosophy of mind and studied AI at Duke (had a guest lecture of my 10 student class from Daniel Dennett which was a huge highlight for me!), big questions around conciousness that Lex brought up. This was undergrad level so I am only aware of the bottom 10% of most fundamental concepts. I have always been extremely envious of theoretical physicists because of the incredible gifts they have for mathematics and the technical complexities needed to advance the most complex concepts humans have ever created... concepts which defy all our intuition.
All that to say... this is one of the most fantastic discussions I've consumed. It dives heavily enough beyond the basic facts we all know and have heard about quantum mechanics, black holes, curvature of spacetime, etc... that it gives someone like myself at 40 at least a reminder of what it was like to want to think hard about these topics, take the challenge of trying to understand a little more fully ideas that are very hard to wrap your mind around.... and to get real joy out of it.
Most content I've seen is either frustratingly regurgitated basic concepts to get the view from the 19 yr old college freshman smoking pot... or (as I've seen on Lex's podcast some... sorry Lex) the far too technical discussions. Sometimes those technical discussions are just legitimate academic interactions that aren't really intended to be consumed in any useful way by someone who is not an expert in the field... that's completely fine... but sometimes the discussions are intended for a wider audience but the expert can't be bothered to unpack complex concepts or just has an air of arrogance (Weinstein... though I am fascinated by him).
Strominger sits right on the perfect balance for the audience... he won't spend too much time trying to explain concepts which cannot be understood without the rare expertise he possesses. But he paints a larger picture and gets to the point of what the advancements may mean.
Kudos for this, I have spent 4 hours watching this 2.3 hour podcast because I will go back to better understand a statement or section more fully. Thank you for stimulating this once eager mind
this is one of those rare interviews that I can keep listening to, over and over, and it stays interesting/entertaining
Really loving this. Lex, being listening to your podcasts for a while and you’re evolved into a rockstar host
Black holes have to be THE most fascinating subjects of past Century. Thanks Lex and Robert 🕳️
Intending on adding relevant info to what was said in the lecture -
How to measure the error/distance of a theory from the absolute theory or
from a previously existing theory?!
I feel the lecture require a talk about the system by which you compose theories. Which is based on an intention-management system.
Therefor I suggest attaching an error value on a theory, derived from the
errors coming from using the theory along a certain intention.
Giving us, a spectrum-tree of [error per intention], for the whole theory.
Which will make it easier for us to choose the theory, once we know what we want to achieve, by ordering the theories by error on the known intention.
Great podcast. Wish it could have been 5 hours. Hope you'll get Sabine Hossenfelder down the road. Great work as always Lex
🙏
Sabine would be dope
I don't really like her. She's a very gifted educator and has tons of charisma, but to me, she seems to be very obtuse when it comes to new ideas. Oftentimes dismissing things without delving deep into them. She's too eager to criticize or debunk anything unconventional, in a field where unconventional things were proven to be right over and over again. As an experimentalist, she's great, but when it comes to theoretical physics, we need people that think outside of the box, that are able to break the boundaries of what we already know. Those people will always be mostly wrong, but on rare occasions, they are right, and this pushes things forwards. Sabine is not really debunking anything, she just doesn't agree with anything outside of things we already know, and to me at least, she does not seem to be willing to push things further. Also, on more that one occasion she admitted being very shallow and not wanting to thoroughly dive into in trying to understand and verify a theory, before "debunking" it.
She's definitely smart, can explain complex concepts in an intuitive manner and has her personal style. It's just that I can't see her as productive, when it comes to theoretical physics.
I like how easily he explains concepts and how humble he is. Others I my opinion overuse complex words just for egotistical reasons lol.
Agreed lol. Overused to the sense certain parts don’t really make any sense at all or maybe it’s just that hard to explain 😂
I don't know I think it's just the way they talk and have it in they head maybe they think normal people understand it
@@Error_-qz2zr thats a good point when putting yourself in their shoes
It's amazing how can someone explain difficult, interesting physics topics in layman's term.
I thoroughly enjoyed this. What excellent conversation. I could type an essay but will instead leave my mind to ponder
I'm surprised by how much I laughed out loud during this podcast. ❤😃 I very much enjoyed this convo. Thank you!
To answer what is gravity, is it not just the antonym of entropy? I feel like negentropy and gravity are synonymous.
"Now is the best time in quantum physics." "Fortunately, it's always 'now'!"
Yeah…LOLs!
I am grateful for two rational men discussing at normal talking speed with out arguing or spewing dogmatic theories .
Since I read Hawking's book in the 90s, I have never gave up my attempt to understand physics and the matters he discussed. As an attorney my math and science education was not extensive, although computerized legal research in the early 80s required an understanding of algebra in developing queries. I wish I would have had math and science teachers who had not killed my early interests. I think my insatiable curiosity is the greatest gift in my life. Thank you for moving me further along the path to understanding. I deeply appreciate your videos.
Curiosity is the key to lifelong learning, no matter the subject matter.
Ending with a Heisenberg quote after a discussion about what is scientifically possible and what responsibilities scientists bear for what is done with their discoveries is perfect. Thank you.
I love the amount of space themed episodes you have!
It was a beautiful thing, a precious moment in time, to witness the admiration you have for each other and your work respectively. Magic and easily the cherry atop the icing of another well-baked interview.
❤you continue to have one great interview after the next. Great job, Lex!
I told my parents once that it's boring when everything is easy . They looked like I had 2 heads . Im glad I heard dr. strominger say that . Challenges are exciting when you are confident . ❤ from 🇨🇦 , thank you lex
After watching The White Lotus series, specifically the scene at the winery where the topic of mimetic desire is discussed, I have become fascinated with the concept of Mimetic Desire and currently reading the book Wanting: The Power of Mimetic Desire in Everyday Life by Luke Burgis. It’s amazing how mimetic desire can influence human behaviour both consciously and subconsciously for good and bad. Thought I would share this with the hope that a conversation with Luke on you podcast would be very insightful given your history, knowledge and passions.
Every time I listen to your podcasts I feel like the only fool in the room and thats good because it means I have something good to learn and listen to.
You are an inspiration to me Lex and everytime you invite someone to your podcast I cannot wait to consume the information provided.
Thank you!!!
Lex You should do a podcast where you interview chat GPT, and let it give it’s responses verbally. That should be fun. You would get a lot of correct answers and you would get a lot of very weird replies. I’m sure you could fit that into a two hour show!
You could even use a Podcasts like this one, just by cutting in your questions and let the chat bot reply. That would be interesting to see how different or similar it is to the replies that you got from Andrew Strominger!
thoroughly enjoyed this one! keep it up!
I’m an hour in and understood nothing . I will not give up.
😅
I have been watching scientific talks for 3 years and I am very proud to say I understand most of the physics theories that are out there and I am starting to get into the details now . Don’t give up it’s rewarding as hell
Thank you for the work you and your team do Lex!
Does Alex have a team? Wow that would be interesting to find out what goes on behind the scenes of the podcast
It is an absolute honor to sit in on these conversations.
Why are you so impressed by bullshit? :-)
Guy is a geinus understands the fundamentals to an insane level, it's incrediblehow easy he makes it seems
Intuitively, Black Holes are drain plug-holes that allow equilibrium between our Universes and other Universes.
Its nice to see dr.Leonard Hofstadter is doing well
Bazinga
2:08:30 Lex, is there anyone in academia who doesn't think there's life with ways like our own observable by us? I don't think in any of your interviews, anyone has even remotely erred towards that position, no?
Im something of a scientist myself you know
I'm a 3 star armchair General, truth be known
We all are one way or another
Wow omg I had no idea! How long have you been keeping this secret? Does the media know, I've not seen anything on the news yet, Have you had the Nobel Prize phone call yet? I did hear a small group of people are thinking of starting a religion to worship you, give it a few months and you could be more popular as god! Unless you are god, omg I repent I repent please save me! I can die happy and fulfilled now, thankyou my Lord 🙏😇
Really?! So where can we witness the magnificence of your scientificityness, your honorable brainyficity?
If we are all scientists, why isn’t everybody happy and the ecosystem in balance? Why are we planning to move humanity to Mars to escape earth’s destruction? Nobody ís planing to destroy Earth… Except for…..? If you can answer that simple question….You might even be a scientist
Could the phrase “entropy always increases over time in an open system” be understood as “the total number of small units of space time always increases in an open system”? IE: quantum fluctuations are due to the cosmological constant as small units of space time spontaneously appear in our universe over time. Maybe there is a limit of space time curvature that above which new units of space time could not happen? This is why we don’t see expansion of gravitationally bound systems but the universe overall is? This is why it’s so hard to describe flat space time?
I liked how Professor did not dumb down things and kept the level of explanation that I did not understand fully everything, but this is better than simplifications, which are plenty. Definitely a great podcast! Thank you, Lex, and best of luck to Prof. Strominger.
I've watched the first 10 or so minutes and I felt that he dumbed things down a lot, like he has no idea Lex's usual audience. I'm glad that it will get better later on.
Thanks for the comment, it motivated me to get past the beginning.
@@jonsnow7092 glad to hear it helped and yes, he gradually increased the difficulty, so even Lex, it seems, did not grasp everything he said :)
@@experiencelife3237 Thoroughly enjoyed the episode, amazing conversation. Thanks again!
Please keep interviewing science people because our culture needs more of this. Thx for your efforts
"The information contained in an English sentence or computer software does not derive from the chemistry of the ink or the physics of magnetism, but from a source extrinsic to physics and chemistry altogether. Indeed, in both cases, the message transcends the properties of the medium. The information in DNA also transcends the properties of its material medium."
Stephen C. Meyer
Hmm 👀
Info theory is fundamental.
Is there a good reason why we can't assume spacetime is made of gravitons, then let gravitons be the building blocks of wavefunctions. And finally, we can control gravitons as they are the entanglement between two entangled photons.
If we do it this way, we can create a quantum gravity theory and then perform experiments on it.
Why are you making it harder than it is?
Great interview, Lex I really love your understanding and amazing questions, keep up your great work!
Let’s nominate Friedberg to be the Chief Moderating Officer. Loved this episode’s pace, discussion and vibe. I think it comes from each of the hosts to speak their view without interruption.
Very interesting. Thanks for sharing your ideas about the responsibility of AI/ML researchers and his response to your question about weapons. Certainly the issues of AI military uses and the scientists role in weapons have some ethical parallels though the rapid development of machine capabilities is challenging our ability to imagine the potential consequences. Though I loved the physics of this piece, the bit at the end is also important.
I always think of Les too as Andrew said at the end...it is just amazing that he can discuss things at the level of his guests on so many varied topics. Kudos, Lex and many, many thanks~!!
🧡Physics. Great intro about seeing infinite copies of one’s self after the photon swings back around a black hole to itself. 😊
Is there any way that because we are particles or gathering of particles near black holes that the connection that we have to blame black holes for subatomic forces Like the strong force connection Between the proton and the electrons could this be achieved in thes presser, could that be where these massive forces are stored/made Like quantum clustering or something?
Lex needs to interview a farmer
good comment.
This is one of the best introductions ever. From now on I want to understand new concepts. Thank you guys.❤
I have a question.
If nothing can exceed the speed of light, yet, something is basically sucking (for lack of better word) light from escaping. Meaning, what happens to the light? Is it just turned into slow light, which is what? Does it pull those photons backwards? But not faster than the speed of light itself? How does it capture the photon, unable go up to the speed of light? How does that work?
Good question!
Light can't go faster than it already is. However, it's not fast enough to reach the escape velocities required to fight the gravitational pull of the black hole.
I appreciate this fella stating gravity is a wave. That whole “Graviton” absolutism we went through a while back was maddening.
This was great. Thanks! Can you pleaaaaaaaase bring Sean Caroll back, Lex?
Only 25 minutes in and this is so good. Thanks for this.
I met Andrew today at Cambridge university. He did a talk on black holes for the Andrew chamblin memorial lecture. Very interesting guy and gave great insights into string theory and information theory in relation to black holes especially when he was asked questions.
Actually, the escape velocity from the Moon is not 7.0 km/s as Strominger states,
but only 2.38 km/s, which makes sense - the Moon has only 1/6 the mass of the Earth,
which has an escape velocity of 11.2 km/s.
I am dismayed that the audience listening to this podcast have not picked up on this...
We have to pose our questions in ways that are not self contradicting. Information is a human concept. It requires an observer to both determine and measure its value. By the definition we've given it, a black hole is a region of spacetime that we cannot observe, so there is no way to determine whether what we call information exists in a place that we can't observe.
even time is human concept and the flow of time is human concept. we don't really know how time percieived by other beings
Lex Freidman is underatedly hilarious
Fantastic interview. Thanks to both of you.
