Amazing thing is that I thought the exact same thing, before even seeing your comment. The resemblance and the mash up,makes me think,they fell into a black hole,and somehow those two made it out,and decided to talk about it.
The world needs more scientists like Leonard Susskind. Such a great communicator for such complex subject. He makes us understand the universe just a little bit more.
Leonard Susskind is simply the best! He can explain such a complicated phenomenon in really simple words which are understandable to practically anyone. Infinite kudos to him! He is my favorite lecturer.
I'm a big fan of this guy. His TH-cam classes are fun and enlightening. I'm so old I'm proof that it's never too late to learn challenging stuff. I hated physics in high school. It wasn't as interesting as girls, pool, or baseball. But it's how things work, and I'm having fun with it in my ...ah....golden years.
31 year old dude here, and just getting into astrophysics and gravitational waves. Had my fun already (even though I was into opposite from you: guys, guitar and drums.) space is fuckin awesome.
I love how he explains things - It allows us non-physics to not only understand but also have a fascination and yearning to learn more about black holes. Thank you!

I dunno. His two interjections kind of bothered me because I wanted to hear how Susskind was going to describe them. For example when he blurted out, "the point of no return", I didn't think that is what Susskind was describing--even though it's true of black holes and Susskind went with it. What I thought he was describing was "the point where information is no longer transmissible". We all know there is a point where gravity in inescapable, but this didn't seem to be the crux of his analogy.
This interviewer whose name ive forgotten is brilliant! He knows a lot about the subject but lets people who know more and who can communicate fascinatingly about their subject communicate!
@@soumyojitpal3399 You can read elsewhere in this thread (immediately below for me...but that is probably just my view). Even in this talk he gets it wrong. A thing stays visible at the event horizon forever? Really lets look at that. OK So the event horizon according to Susskind is because the object is being pulled in faster than C. And that light carries momentum and will never reach you. So light is completely a particle then! But no! It is not. Light is emitted by mass by vibrating what you call the fabric of space. Just like a jet in the sky. Do we suddenly not hear supersonic jets? No...we still hear them. Even though they are going way faster than sound...because the media carries the signal. The signal isn't particles shooting out of the jet to our ears. The sound proves this. So the ONLY other thing that could be happening is that the light is being pulled either directly or the media itself was being pulled. If it were the media (fabric of space) and we believe in an expanding universe, then you would at a very high speed see things being sucked into black holes. But Susskind and all the Big bangers (Similar to flat-earthers) do not realize how the universe works. The reason black holes are black is because of a upward shift in frequency of light far beyond gamma rays. This can happen because time-space (ether field) is much denser near a black hole because it creates ether. When that super high frequency light travels to less ether dense space the signal can no longer be carried. This loss of signal makes the black hole appear black. Supporting evidence. Matter getting sucked into a black hole and emits a gamma burst. It does this as it enters more ether dense space until it too is clocked too high and signal is lost. Pulls can not exist. So how else does a black hole become black. My theory is THE only game in town that fits. If the black holes are sucking in space then this should counter the expansion of space and we should be shrinking because this would be an immense power. Background radiation is from something described as a "blackhole universe". Not quite right except that black holes and this frequency mismatch are the reason.
And they think about black holes in terms of plumbing. "Imagine if the kitchen sink was infinitely large, and water was sucked out of it at a speed greater than sound."
As someone else commented. What a privilege to listen how something so complicated as Black Holes can be explained to us less gifted and yet leave one with a whetted appetite for more. Many thanks 🙏🏻

I used to feed sparrows when I worked at a park. Peanut butter crackers. They learned to come when I whistled...hahah...come in like a big cloud and gather around me. They wanted Lay's brand not Tom's. Tom's were cheaper of course. I could crunch them all up together and they would pick out all the "good" stuff.
Rather than losing the information, could the singularity just become a gateway to transfer the information to another bubble universe. Love these discussions with this super intelligent and easy to follow Doctor Susskind.
Black holes have always fascinated me since I was 13-year old from the time my much older friend Vivek Rao, an Electronics Engineering student from IIT, Madras, explained it to me. These great scientists explain it in such a simple and interesting manner. Thanks.
Splendid interview! It's so so kind of Dr. Susskind to illuminate on this luminous topic that light and other objects with "information" embedded within of not being able to escape the stranglehold of the black holes. Yet they expand our 'horizons' of understanding the principles of contemporary physics and even help amalgamate the old with the new. Information isn't lost. In fact, nothing is ever lost. From the absolute (say the absolute zero Kelvin) arise the "quantum jitters", like Shakti (Nature) arising out of Nothing (Shiva)! Be it the Big Bang or the Big crunch, information will be ever etched in the fabric of the DNA of the Cosmic Consciousness, like the Akashic records (Boltzmann's brain). Amalgamation and interchangeability is nothing new. The wave and particle properties of light and even macrocosmic objects can be boiled down to the quantum properties of wave function and its collapse thereof. Advaita (non-dualism) vedanta had long proposed the idea since the ancient times by the great Indian sages. Erwin Schrodinger, Werner Heisenberg, Albert Einstein, Aldous Huxley had experinced it ituitively and dwelled on it. We are not just particles, merely confined to some location in space, rather we need to think of us in terms of waves spread out over the whole Universe. Professor Sean Carroll had once said in a lecture that physicists won't tell you this fact that we are waves in reality and not just particles. We ever live. We don't die, ever! "There's got to be Just more to it than this Or tell me, why do we exist? I'd like to think that when I die I'd get a chance, another time And to return and live again Reincarnate, play the game Again and again and again and again" .... Iron Maiden, Infinite dreams
Well, this is the edge of knowledge as far as theoretical physics is concerned, and it would be really something when we do reconcile the two understandings of the very big and the very small.
@@darksu6947 very true; because once we understand how the very small makes the very big, we just might even understand what is consciousness! Everything changes after that!
All of Creation begins as THOUGHT and expands outward in DENSITY. Focused thoughts create the energy molds(thought forms) within the nonphysical dimensions and act as the sub structure for matter.....Black holes lead to that sub structure...thats where our physical Universe originates from...to travel through a Black hole...to the "other side" if you will,you would have to give up your "physical dense form" and transform into your much finer ,higher vibrational energy form...after you get to that realm...there are even finer realms to explore and experience...sounds all woo-woo I know, but its REALITY!
I always refer to mr. Susskind as the plumber physicist, in my own opinion he is a true genius,humble to declare that he was wrong on the multiverse theory after he was one of the most influential people on it,but he keeps on going looking for the truth. If we were to meet I believe that we can really be friends.
"Calculations of a clam chowder dawn reach into the outer limits exploiting the mysteries of seaweed kept busy in a bookstore. Black holes shape your vision of seagulls converting energy into mass and genetic prices rushing into a grape jelly future. Caffeine-free snow drifts will ward off alien intervention and annihilate rubber-band monitors, expanding a diversity of goldfish trained in clinical psychology left intact." ---Albert Einstein
when we were in highschool physics, my friend, last named Rays went to visit his grandmother in Florida. He returned sunburned and we asked him if this was because of grammarays.
Great explanation. I once read of a theory that said black holes ‘seeded’ other universes: the information that was sucked into it came out again, on the ‘other side’, in another universe. It has always stuck with me.
A hole into another universe is just a theory. it assumes that our space-time fabric can be punctured. Suppose Space-time is infinitely elastic. Nobody knows and we will probably never know.
"We are now in a position where we have to reconcile this. We have no choice. Oh, of course we have a choice...!" Such an appropriate remark in relation to determinism yielding to new concepts
Listening to this it seems to me we don't really understand black holes. Reminds me of my cosmology instructor who said the fact that most of the universe is dark matter and dark energy means that we don't really know what the universe is. It also means our theory of gravity may be wrong or incomplete.
"It also means our theory of gravity may be wrong or incomplete." Well duh. it doesn't take a degree in physics to realize that General Relativity is incomplete. it doesn't square with Quantum Mechanics bro.
Leonard’s command of metaphor in explaining heavier concepts (pun intended?) is a big part of what drives his quality, I think. We all need good metaphors for things.
I didn’t get the right physics break down of what I was looking for lol, but I’m glad about what I found. It shows how much we think we know about black holes but still so far from ever actually experimenting and learning all of its true properties. If we knew everything we desperately want to know to know about the event horizon we could probably learn how to use that area to manipulate the singularity and use the black hole as a whole to provide endless energy.
I know we barely know enough about black holes, but white holes intrigue me. I feel that universes are created from matter and gas that was digested by a black hole, juttering through the otherside of the conduit.
@@atrocious_pr0xy I'm thinking along similar lines. The common theory is that black holes are the result of a collapsing star. That may be true. I am not familiar with the physics of that theory. But I am thinking that black holes create the galaxies that they are at the center of. It is now known that black holes eject a stream of energy and matter at their "poles". This would create an oblong galaxy. As the black hole rotated over time the oblong galaxy would become a spiral galaxy. This fits the observations of the Hubble telescopes pictures of the early universe where oblong galaxies outnumber the spiral ones. But billions of years later spiral galaxies are in the majority.
Thank you. I thought I was the only one who found the constant camera shot on the interviewer to be annoying. Perhaps he was looking for the eye roll when he is discussing quantum physics and then suddenly switches to giving a talk to an elementary school about polywogs, tadpoles, chickens and ducks.
Black holes are fascinating and mind bending, tbh I think they connect to a different part of the universe or multiverse that we cannot see and all the information and matter goes there and creates another multiverse bubble.
Black holes may be extremely cold (near absolute zero) to us from the outside, but if the gravity of the black hole swallows up all matter and energy, then how do we know that all that mass and energy inside, which cannot escape the event horizon and is trapped inside, is not in fact extremely hot inside? How do we know what the temperature is just inside of the event horizon? What are the astrophysical jets that come from the black hole? How do black holes convert mass into energy? Articles about LIGO discovery state that some percentage of mass from black hole mergers is converted into energy, resulting in a black hole that is smaller than the sum of the original mergers. They found two black holes - of 36 and 29 solar masses - merging together to create a new black hole of 62 solar masses. Where did the other 3 solar masses (about 5% of the total system's mass) go? Into the energy of gravitational waves? So, it isn’t that the black holes are losing mass but that the total amount of energy in spacetime is transforming from one form (in two well-separated, unbound masses) to another form (a single, tightly bound mass plus gravitational radiation). How does this process happen? If in the very last second of the merger is where most energy is released (in the form of gravitational waves), then these gravitational waves are pure energy (not particles of any kind)? It is accepted that nothing escapes black holes. So: how is energy radiated from black hole mergers? How are these gravitational waves able to escape black holes?
I don't think anything escapes the black holes until they implode and then explode tearing a hole in spacetime creating a wormhole, where some energy escapes into another spacetime or dimension
Leonard Susskind reminds me a lot of my father. They look alike. Susskind is just a lot smarter, and he also has the added advantage of still being alive.
For the model, just start with a bathtub with a drain, but imagine a round bathtub with a big drain in the center. If you put a rubber ducky in the bathtub away from the center, it hardly notices the movement of the water towards the drain. But if a rubber ducky floats near the center, the rushing water will pull it down the drain. Now just imagine a bigger bathtub, and then an even bigger bathtub... An "infinite" lake just means the bathtub is so big that most rubber duckies will never encounter the drain, or even notice it, because they're so far away from it. But the drain is there, and every once in a while, an unlucky rubber ducky will unhappily float too close and get swallowed.
I was just about to comment something like this before I found your comment. I get what he means by this (as some here went to great length to explain). But I think what you're getting at (and what I was thinking) is that from a purely mathematical perspective, it makes no sense.
@@chrissekely I think what you mean is that from a purely _physical_ perspective it makes no sense. It is only from a purely mathematical perspective that reasoning about infinity does make any sense.

I love the fact he talks about Galileo's experiment to combine two disparate worlds and then he uses a combination of plumbing and quantum physics to show a dumbass like me what's going on in the universe.
He speaks an English we can understand. ☺
Douglas Adams and Terry Pratchett are also really good at that and in very similar ways. Only making the idiocy of it just a little more obvious because you know they are writing fantasy/fiction.
I hope that helped, mostly for not thinking of yourself as a dumbass ;-)
Just wrong reference! Throwing rock Wasn’t Galileos but mewtons idea.

I love these talks even though i understand it on a basic level. It makes me feel smart and fascinated.
Leonard Susskind is amazing.
My cat understands this very well…..if I mix chicken together with duck in his food dish, he will NOT eat it. He understands he must not confuse the information as it enters the black hole of his appetite.
I used to feed sparrows when I worked at a park. Peanut butter crackers. They learned to come when I whistled...hahah...come in like a big cloud and gather around me. They wanted Lay's brand not Tom's. Tom's were cheaper of course. I could crunch them all up together and they would pick out all the "good" stuff.
😀
maybe he knows what happens when it comes out the brown hole and he doesnt wanna go through that
Susskind is such a riveting speaker.
3:12 interviewer caught using earbuds listening to music. Can't stop nodding to the beat.
We need more teachers like Leonard Susskind.
Great video.
Fascinating discussion.
😊😊😊😊😊
Fascinating interview. I've never heard things explained this way.
Rather than losing the information, could the singularity just become a gateway to transfer the information to another bubble universe. Love these discussions with this super intelligent and easy to follow Doctor Susskind.
Bro no one said that you’re smoking ganja
Roger Penrose doesn't seem to think so.
After watching a hundred videos in black hole and still being confused … I now have some clarity thanks to this man
This man is a hero
Black holes have always fascinated me since I was 13-year old from the time my much older friend Vivek Rao, an Electronics Engineering student from IIT, Madras, explained it to me.
These great scientists explain it in such a simple and interesting manner. Thanks.
I know him. That’s crazy. Famous guy!
Wow! That "both domain" theory about black holes hit me like a rock!! I get it!
Splendid interview! It's so so kind of Dr. Susskind to illuminate on this luminous topic that light and other objects with "information" embedded within of not being able to escape the stranglehold of the black holes. Yet they expand our 'horizons' of understanding the principles of contemporary physics and even help amalgamate the old with the new.
Information isn't lost. In fact, nothing is ever lost. From the absolute (say the absolute zero Kelvin) arise the "quantum jitters", like Shakti (Nature) arising out of Nothing (Shiva)! Be it the Big Bang or the Big crunch, information will be ever etched in the fabric of the DNA of the Cosmic Consciousness, like the Akashic records (Boltzmann's brain).
Amalgamation and interchangeability is nothing new. The wave and particle properties of light and even macrocosmic objects can be boiled down to the quantum properties of wave function and its collapse thereof. Advaita (non-dualism) vedanta had long proposed the idea since the ancient times by the great Indian sages. Erwin Schrodinger, Werner Heisenberg, Albert Einstein, Aldous Huxley had experinced it ituitively and dwelled on it.
We are not just particles, merely confined to some location in space, rather we need to think of us in terms of waves spread out over the whole Universe. Professor Sean Carroll had once said in a lecture that physicists won't tell you this fact that we are waves in reality and not just particles.
We ever live. We don't die, ever!
"There's got to be
Just more to it than this
Or tell me, why do we exist?
I'd like to think that when I die
I'd get a chance, another time
And to return and live again
Reincarnate, play the game
Again and again and again and again" .... Iron Maiden, Infinite dreams
Well, this is the edge of knowledge as far as theoretical physics is concerned, and it would be really something when we do reconcile the two understandings of the very big and the very small.
That will be the day that things change forever. I hope I’m around to see it.
@@darksu6947 very true; because once we understand how the very small makes the very big, we just might even understand what is consciousness! Everything changes after that!
You would still be lost.
All of Creation begins as THOUGHT and expands outward in DENSITY. Focused thoughts create the energy molds(thought forms) within the nonphysical dimensions and act as the sub structure for matter.....Black holes lead to that sub structure...thats where our physical Universe originates from...to travel through a Black hole...to the "other side" if you will,you would have to give up your "physical dense form" and transform into your much finer ,higher vibrational energy form...after you get to that realm...there are even finer realms to explore and experience...sounds all woo-woo I know, but its REALITY!
@@balaji-kartha EVERYTHING originates from CONSCIOUSNESS.....but that's another enigma like Black holes isn't it?
I love the chair he's sitting in. 🙂👍
I could listen to Leonard for hours.
Which hours specifically?
@@b.g.5869 yesterday's hours
You can. th-cam.com/users/stanfordsearch?query=s%C3%BCskind
I'm like that with music
I always refer to mr. Susskind as the plumber physicist, in my own opinion he is a true genius,humble to declare that he was wrong on the multiverse theory after he was one of the most influential people on it,but he keeps on going looking for the truth.
If we were to meet I believe that we can really be friends.
And yet he's saying a theoretical thing nobody has ever seen or proven is amazing.
clash of principles, progress begin!
Zthank u for verbalizing this
How beautifully explained. What a great teacher
You girl or a boy??
There are teachers and then there are teachers like Susskind or Feynman.
Or me, i am also good
@@sinisa5567 This is true

amen!
@@sinisa5567 very true senpai
Dr Susskind is such a great speaker.
Best explanation on black holes I’ve ever heard ✨
I so wish I had teachers like this in high school and university.
I hated school and they hated me right back….SO I WENT TO CLASS half baked🥴
they don't teach anything useful.
Thanks John Malkovich, for this great explanation, great physicist and better actor!
"A chicken, a duck and a physicist go into a black hole..."
No punch line yet.
"Calculations of a clam chowder dawn reach into the outer limits exploiting the mysteries of seaweed kept busy in a bookstore. Black holes shape your vision of seagulls converting energy into mass and genetic prices rushing into a grape jelly future. Caffeine-free snow drifts will ward off alien intervention and annihilate rubber-band monitors, expanding a diversity of goldfish trained in clinical psychology left intact."

when we were in highschool physics, my friend, last named Rays went to visit his grandmother in Florida. He returned sunburned and we asked him if this was because of grammarays.
Wot
Hulk smash 😂😂
Not bad not bad
Hahhaha! Dang!
We? Was it collective thinking, Did you all ask simultaneously?
Top Class elucidation. Hats of to you gentlemen. Please share more such videos.⚘⚘🌺🌷👍👍
I used to listen to his lectures on quantum mechanics when I worked in a warehouse; an excellent teacher.
Bro if u understood a thing u wouldn't be in a warehouse would u 🤣
@@geert574 Why? I worked in a warehouse, and now I'm doing a PhD in physics.
Great explanation.
I once read of a theory that said black holes ‘seeded’ other universes: the information that was sucked into it came out again, on the ‘other side’, in another universe. It has always stuck with me.
They're in this universe. It's a point, not a hole.
Maybe what they have observed as blackholes are similar entities as the theoretical blackholes, because blackholes only exist in theory.
It's like saying something travels at the speed of light, where in our world such things don't exist.
A hole into another universe is just a theory. it assumes that our space-time fabric can be punctured. Suppose Space-time is infinitely elastic. Nobody knows and we will probably never know.
@@rocren6246 black holes aren’t a theory when we have photographs of them
"We are now in a position where we have to reconcile this. We have no choice. Oh, of course we have a choice...!" Such an appropriate remark in relation to determinism yielding to new concepts
The shots of the interviewer just bobbing his head up and down while the other is talking are hilarious
yes, but you should see his suspicious look when the interviewee is talking BS (plenty of these BTW)
best part. he's engaged
I gota turn the phone away when I watch cuz of this
This what I do when someone asks me a question
He looks like a weiner
Listening to this it seems to me we don't really understand black holes. Reminds me of my cosmology instructor who said the fact that most of the universe is dark matter and dark energy means that we don't really know what the universe is. It also means our theory of gravity may be wrong or incomplete.
"It also means our theory of gravity may be wrong or incomplete." Well duh. it doesn't take a degree in physics to realize that General Relativity is incomplete. it doesn't square with Quantum Mechanics bro.
Leonard’s command of metaphor in explaining heavier concepts (pun intended?) is a big part of what drives his quality, I think. We all need good metaphors for things.
A great physics storyteller! 👏
man, not sure about all that cause i m clueless but this a reasoned seasoned person
This guy looks like he could play Archimedes, Galileo or Da Vinci perfectly
John Malkovich?
I would love to see him as da Vinci with a heavy NYC accent.
Or Leonard Susskind even.
Except when he talks ...
i love that this brilliant man still has his bronx accent.
My mind is blown. He explained it so well
This guy is a great talker and explainer
Seriously
Wow! Thanks for the clarity
I didn’t get the right physics break down of what I was looking for lol, but I’m glad about what I found. It shows how much we think we know about black holes but still so far from ever actually experimenting and learning all of its true properties. If we knew everything we desperately want to know to know about the event horizon we could probably learn how to use that area to manipulate the singularity and use the black hole as a whole to provide endless energy.
I know we barely know enough about black holes, but white holes intrigue me. I feel that universes are created from matter and gas that was digested by a black hole, juttering through the otherside of the conduit.
@@atrocious_pr0xy I'm thinking along similar lines. The common theory is that black holes are the result of a collapsing star. That may be true. I am not familiar with the physics of that theory.
But I am thinking that black holes create the galaxies that they are at the center of. It is now known that black holes eject a stream of energy and matter at their "poles". This would create an oblong galaxy. As the black hole rotated over time the oblong galaxy would become a spiral galaxy. This fits the observations of the Hubble telescopes pictures of the early universe where oblong galaxies outnumber the spiral ones. But billions of years later spiral galaxies are in the majority.
LS is so brilliant and so human. A great man.
AMAZING video!!
Brilliantly articulated
And here I was thinking the “point of no return” was Taco Bell’s drive-thru line…
Nah its when you don't pull out and get a girl pregnant
😂
That was extremely interesting and beautifully explained.
A joy to listen to
Thank You
This is so frickin' COOL and terrifying at the same time!
This is such a *fantastic way of teaching the material!* Stellar! 🙌🔥
"Stellar"....ㄥ丨ㄒ乇尺卂ㄥㄥㄚ!
Quasi-stellar, even.
One of the first physicists I could follow closely, great analogies and command of lay person communication. His information was conserved on my end.
What theory was it that convinced the camera operator to focus so much on the guy who wasn't actually speaking?
To tell us how focused we should be
The camera operator is in love 😻
it was an attempt from the cameraman to show how big of a clown he is.
Thank you. I thought I was the only one who found the constant camera shot on the interviewer to be annoying. Perhaps he was looking for the eye roll when he is discussing quantum physics and then suddenly switches to giving a talk to an elementary school about polywogs, tadpoles, chickens and ducks.
You mean the editor cutting in reaction shots... they linger too long, but that's an editing issue and has NOTHING to do with camera operators.
This man is a master at explaining things extremely complex to where the average person can understand. You feel smarter every time you listen to him.
Given that he believes in Relativity, he doesn't know what he's talking about.
You can't feel that much smarter if it took similes for you to try and understand such a complex process.
hes master of nothing
At exactly 10:00 when the interviewer asks "that's through a quantum mechanical effect" Leonard gets so surprised but also excited that he knows :D
Would love to see new interviews with these people.

If a black hole is a perforation in spacetime then the manifold itself must have a perforation. Toroidal or Klein.
Leonard Sukind is simply the great scientist, philosopher and teacher .Very few measure up to his standard!
Black holes are fascinating and mind bending, tbh I think they connect to a different part of the universe or multiverse that we cannot see and all the information and matter goes there and creates another multiverse bubble.
interesting theory
I used to watch this man's Stanford Lectures in my leisure
And i thought waiting for new episodes of One Piece was bad..
Could listen to this all day.
Black holes may be extremely cold (near absolute zero) to us from the outside, but if the gravity of the black hole swallows up all matter and energy, then how do we know that all that mass and energy inside, which cannot escape the event horizon and is trapped inside, is not in fact extremely hot inside? How do we know what the temperature is just inside of the event horizon? What are the astrophysical jets that come from the black hole?
How do black holes convert mass into energy? Articles about LIGO discovery state that some percentage of mass from black hole mergers is converted into energy, resulting in a black hole that is smaller than the sum of the original mergers. They found two black holes - of 36 and 29 solar masses - merging together to create a new black hole of 62 solar masses. Where did the other 3 solar masses (about 5% of the total system's mass) go? Into the energy of gravitational waves? So, it isn’t that the black holes are losing mass but that the total amount of energy in spacetime is transforming from one form (in two well-separated, unbound masses) to another form (a single, tightly bound mass plus gravitational radiation). How does this process happen? If in the very last second of the merger is where most energy is released (in the form of gravitational waves), then these gravitational waves are pure energy (not particles of any kind)? It is accepted that nothing escapes black holes. So: how is energy radiated from black hole mergers? How are these gravitational waves able to escape black holes?
Soo many questions but no answers 🥲
I'm thinking it has something to do with Hawking Radiation
I don't think anything escapes the black holes until they implode and then explode tearing a hole in spacetime creating a wormhole, where some energy escapes into another spacetime or dimension
yes it could be hot inside. it can also be hot outside. the temperature is that of the event horizon itself, with nothing else around
@@DillaCat So the information that must not be lost is in the Hawking radiation that gets out?
Leonard Susskind reminds me a lot of my father. They look alike. Susskind is just a lot smarter, and he also has the added advantage of still being alive.
RIP
Explained poetically and elegantly. Wow!
Fascinating discussion. Thanks.
"Infinite lake".
Alright.
"Drain in the center."
Lost me man.
Drain in a place kinda like a center I guess lol
For the model, just start with a bathtub with a drain, but imagine a round bathtub with a big drain in the center. If you put a rubber ducky in the bathtub away from the center, it hardly notices the movement of the water towards the drain. But if a rubber ducky floats near the center, the rushing water will pull it down the drain.
Now just imagine a bigger bathtub, and then an even bigger bathtub... An "infinite" lake just means the bathtub is so big that most rubber duckies will never encounter the drain, or even notice it, because they're so far away from it. But the drain is there, and every once in a while, an unlucky rubber ducky will unhappily float too close and get swallowed.
I was just about to comment something like this before I found your comment. I get what he means by this (as some here went to great length to explain). But I think what you're getting at (and what I was thinking) is that from a purely mathematical perspective, it makes no sense.
@@chrissekely I think what you mean is that from a purely _physical_ perspective it makes no sense. It is only from a purely mathematical perspective that reasoning about infinity does make any sense.
@@kdub1242 Thanks for the response! But no that's not what I meant. Maybe that's what I should have meant though. I do understand how anything infinite makes no sense from a physical perspective. You've totally got me there. Please explain, though, how to even in a purely mathematical sense find the center of an infinite plain. Please understand that I'm not upset at all. I really enjoy this sort of exchange of ideas. Please let me know where you might take this from here.
So well explained tahnk you Professor Leonard Susskind.
