That was the best explanation of black holes I’ve ever heard ,I am referring to your first speaker very nice! 🙏
Same here!
It was Kip Thorne.
Finally, I understand a bit about black hole.
Indeed, if the circumference is 3 miles, then the diameter will measure 1 mile, roughly, but no it is much longer. Geometry muddles long and short. Similarly what is massive and massless. The quantum field plays the tricks, where most particles are massless while W and Z bosons are massive and yet appear and vanish. Same with dark matter and dark energy. In short we have no clue. All we can feel is cosmic consciousness and human consciousness are entangled.
He literally wrote the book on Gravity.
So cool watching these older episodes from the perspective of the additional knowledge we have now.
This is sublime, what a mighty benefit TH-cam is, a stand alone for catch up learning. I love it, Cheers SBM.
So happy I came across this channel. Thanks so much for the awesome videos
I’ve been watching for so long, and just for the first time really appreciated the opening. Very cool.
Excellent explanation. I am no physicist but nice to be given an insight into this subject
Kip Thorne is just fantastic
A fascinating video thank you. Although I really understood only a fraction, enjoyed it immensely. Tim Marshall
Thankful to be able to watch stuff like this.
Can't remember when or how I stumbled across your show. However, I'm very glad I did. Please keep asking the difficult questions and keep up the great work!
Astonishing, as usual. Thank you CTT🙏🏼
Wow wow wow wow ! am eternally grateful to this humble giant of physics Kip Thorn. Wow
This is the best channel I ever came across.
Black Holes fascinate me! 🙂
this was made for when your stoned.
swear down. im feeling it.
You're
Black holes are some of the strangest and most fascinating objects in outer space. I like BH theories and always love to think about them.
I bet you do
you can not see it or measure it yet you believe how dumb
Amazing presentation
8:16 Finally an explanation that makes sense for what happens to the matter at the heart of a forming black hole.
Go Bluejays!!
Really good episode. Interesting to see so many well-informed people opining on the same mystery. Tight presentation. Thoughtful
Yea, this episode is truly closer to truth. This planet and life on it can't just "die" into particles and " life's experiences" into oblivion. The black hole may well be the "the world" of some prior ERA.
Thanks Mr kuhn for the effort and keep up the good work .
From Hker worldwide
I hope I live long enough to be around when they discover what a black hole truly is and what it's purpose is. Also being around when a unified theory of physics would be pretty great too. I also wish I were smart enough to work in this field.
Same.
Video originally aired: 2008
When I thought I've seen every black hole video ever on TH-cam, I find this!
Awesome
Lee Smolin is so soft-spoken and knowledgeable!
Very soothing lol
Yeah I really like him. Fav is Sean Carroll.
I have an affinity for Susskind, but all here are fantastic!
@@quantumrobin4627 I too am a Susskind fan. But pls don't forget Brian Greene, who is also very good at explaining things to non-specialists.
He believes Darwin's natural selection is true for our evolution and of the cosmos/universe (theory of small changes) reflects a basic/fundamental property of nature, that can explain evolution of big bang, life, consciousness, meme etc.
I always thought of black holes as giant recycle bins - that also double as randomness generators for our universe.
Great search
"will that do?" I'm still smiling from that one.
i came up with the idea of black holes creating other universes while smoking hashish in my bedroom back in 94.
When are the new episodes coming......cause I can't wait!
The God view from SagittariusA is absolutely beautiful. Everything is coming toward me in slow motion, all the past. Future is already beyond that Graphic Processing Unit. Hi humans. ⭐
❤️ Exactly. 🥰
All information in our universe could be a holographic projection that we perceive from The Singularity of a black hole. Each black hole, in theory, could have a universe inside of it. Inside of the universe, within each black hole, there could be other black holes with universes inside of them.
I go with a hographic model from which the space time is its projection. A holographic model comes with no origin thus general relatively is enforced without any Lorantz transformation or any space time curvature for compensation.
This way a black hole can be considered as a special fundamental particle with pure discrete energy and angular momentum.
A study of the creation account from The Book of Genesis, in the original language, using alternate possible word meanings, can be enlightening regarding this subject.
I am surprised at the insights in the comments along with the actual interviews. Some very smart people watching too! 🥰👍🏻
@@williamesselman3102 "alternate word meanings" 🤡
The first speaker is an eye opener
Leonard Susskind looks like such a layed back dude. True Guinness
"Kip, what is the structure of black hole?"
I can't stop laughing
Without slightest doubt, you are Woody Allen of the scientific domain!
When the irrational gets everything it wants by destroying everything the rational has created, it becomes locked up. Black holes predict the future of a society that cannot overcome the ego. Imprisoned by a singularity.
So, what happens inside of a black hole, depends on whom you're asking... The idea of children universes was fascinating!
We look for effects that black holes create around them, like "gravitational lensing"
A 'black hole' reminds me of an 'anonymous quantum Hall effect' in the quantum realm. With a larger tensor(s) we could create a Hopf Fibration double helix torus in orthogonal space.
what are you saying? that is complete gibbrish. the quantum Hall effect has nothing to do with black holes. please don‘t try to sound smart by using random words
What if dark matter and black holes work together?
Yes...BH is astonishing indeed!
It was not that at early period before/prior to bigbang(particulations) the initial singularity of the universe itself was a BH.... warping the universal space-time....as the universal matter was only formed sometime after bigbang...how that BH space-time warping was broken to allow (particulations) expansion?
Was't it astonish that sometime after the bigbang, following the formation of early matters(after particulations), the universe expansion rate was able to overcome the critical mass to volume ratio of matter to continue expanding against the gravity at all ?
nah
I wish you'd label the dates these interviews were made...you repeat far too many old interviews
209 means season 2, episode 9 so; 19 years ago, or so.
@@mediocrates3416 any idea why they're recycling their old content so much... It's annoying I subscribed to the channel for new updates, not old stuff -_-
@@Red1Green2Blue3 Every day at 9 they post, plus extra: prolly the more we click the more ad $$ and the more frequently they post the more we click. ... I wanna see one on a *practicle* theory of everything that "matters". 😂😂
All totalitarians repeat rhetoric incessantly
This video is from 2008.
Hoping Robert does a video about the James Webb which found galaxies OLDER than the big bang!!
I never realised black holes were so small
I wish you included penroses ccc-modell
Did Cisco Ramon form the CW Flash make an appearance?
I believe that the Universe is fractal..
Where each Black hole is the big bang of a universe just like ours.
does space change or warp time outside a black hole, and does time change or warp space inside a black hole?
Of course we know now they actually do emit a faint radiation
is there a relationship of time to quantum mechanics inside black hole?
Is the curvature of time and space inside black hole like dark energy?
What we can learn from black holes is that it is not good for One to be alone. - Wald Wassermann
Time is relative and subject to spacial distortion is not an adequate defence in court when explaining why you didn't pay your television licence apparently
A black hole is an inside-out sun. What's on the 'other side'? Of course there's no matter - it's a hole!
My occam's razor answer for blackholes is they are wormholes in our spacetime that lead to other spacetime. But if it is other spacetime not part of our spacetime. Then time here has no effect on time there and vice versa for the other side of the new spacetime made by the blackhole. The two spacetimes can effect each other so we can dump stuff in to the blackhole form our end and we sure as hell can get ripped part by the new spacetimes blackhole. Because the blackhole just formed a new spacetime just on other side of the blackhole from our end. The blackholes wormhole always exits at 0 point the dawn of time when entering form our side. But the spacetime starts the second the new spacetime is made. So this means that funny in the math of blackholes having end points and starting points at the same time is 100% right and makes coherent sense this way. Also mean the same matter will exist is a future that also exists in the past. So the the past and the future can happen at the same time but still cohere basic logic and rules of cases and effect. Just an idea anyways
Whenever I start to think I'm too important I sit incompetent & contemplate on black holes.
I have an old and yet not understood concept, unless the the typical gravitational forces seen on planets and starts where the this massive object wrap the space around them making a curved space leading to gravity. How the black hole could have singularly in one direction due to the immense gravity , instead of the dimension impacted around it why the singularity goes only one direction and what drives it.
could you perhaps try english?
at the singularity of black hole is matter turned into energy? if so, what would happen to that energy?
Remarkable, black holes contain no matter, space retains the shape of the distortion, space time can be engineered to portray these properties then i suppose
A very astonishing thing he pointed out. Black hole is not made out of matter. Inside the black hole you could
see the universe above, but you not have any way to get out, you just do not have any control to material world.
Well, sounds like science just acknowledged we got ghosts among us. No kidding!
like a magnet... nothing in the void...

Singularity = big bang?
Not possible to see past the eveny horizon, not possible to see before the big bang - so in theory a singularity in our space-time could generate a big bang of another space-time?
Mind blown.
Most amazing is they exist only in imaginations of those who won't answer the simplest questions first.
might classic gravity have to do with expanding space, and quantum gravity have to do with contracting time?
could quantum information be separate from space-time information inside black hole, such that as the black hole evaporates the quantum information is left separate?
Just like you can never have enough paint to coat the inside of Gabriels horn, black holes cant be defined on the inside. They can be defined on the outside however as in you can define the amount of paint on the outside surface of Gabriels horn.
I just put lube on my horn.
What if Black holes function within principles of light and projection. Both projector and projection. The holographic nature of light refraction on a spherical surface combined with a resonance??
Singularity is another word for Simplicity...
no, it isn't. they have totally different meanings.
@@cosmikrelic4815 😁🙃😆🙂🤣😂
what happens to quantum information inside black hole?
might energy of objects falling into black hole become quantum information in time that is radiated away with thermal blackbody?
The term black hole is a misnomer in my opinion, they really should have been called invisible holes or something like that, black is a color that is still seen by people
I can tell you what is inside a black hole what its purpose is and how it functions its really very simple, the laws that govern the Newtonian and the Quantum are united within a black hole, eventually the Newtonian will fade off leaving the Quantum at the singularity which will spawn a new universe, I can explain how this happens, it's all very simple, also Einstein's E=MC2 is modified to incorporate information which is all that is left inside a black hole, I can tell you how this works too..
Not a bad theory: Our universe experiences expansion but in relation to our universe black holes experience contraction albeit in their frame of reference: Singularity and expansion...
Are they that astonishing so unbelievable,could they be impossible?
I’m down a TH-cam black hole of videos concerning black holes
can a volume of time expand from black hole? a volume of time with quantum information?
So what would happen if 2 black holes met?
Gloomy music at the begging
It's from Romeo and Juliet...a tragedy
More like mysterious music
If the universe is constantly being destroyed and created, black holes may be the engine.
objects falling into black hole become energy?
diameter of black hole drops of a cliff, like a waterfall or whirlpool?
I still don't get how there could be anything like a singularity when it seems to make no sense for something smaller than the Planck length to exist. Any physicist here could give some insight into this?
that‘s a very good question but difficult to answer but let me try. It's important to understand the context in which statements like "there must be a singularity in a black hole" are made. This context is provided by the model used to derive the results. In this case, it was general relativity that was used to predict the existence of singularities in spacetime. Hawking and Penrose proved that, under certain reasonable assumptions, there would be curves in spacetime that represented the paths of bodies freely falling under gravity that just "came to an end". For these curves, spacetime behaved like it had a boundary or an "edge". This was the singularity the theory predicted. The results were proved rigorously mathematically, using certain properties of differential equations and topology.
Now in this framework, spacetime is assumed to be smooth - it's mathematically a manifold - it doesn't have any granularity or minimum length. As soon as you start to include the possibilities of granular spacetime, you've moved outside the framework for which the original Hawking-Penrose theorems apply and you have to come up with new proofs for or against the existence of singularities. In short, the singularity is something that simply arises from the mathematics but it‘s existence is not certain at all and our notions of „small“ or „length“ are difficult to apply in this context.
inside event horizon of black hole is time?
Why are black holes considered infinitely dense, as opposed to just super-dense?
density is mass divided by volume. what is the volume of a black hole?
@@cosmikrelic4815 For a black hole to be infinitely dense, its volume would have to be zero. So that's kind of a rephrasing of the same question, why are black holes considered to have zero volume, as opposed to just extremely small volume.
@@budweiser600 i don't know, i suppose i was just saying aas far as i can see it is not an answerable question at present. if you consider the black hole to be the singularity then that could be cosidered zero. i don't know what other volume you could use?
The most basic law of nature are second law of thermodynamics and evolution of natural selection the fittest survival. What's singularity? How long does a sigularity last in Vacuum the Absolute (Nothing the Absolute or Antithesis the Empty, suggested by Hegel)? How many sigularities on the surface of (in) Vacuum the Absolute, are there infinite number of it? Does second law of thermodynamics cause a singularity to be disintegrated into ultimate chaos, Lucifer dot the dead (Ldot): every point component of the singularity isolated each other in Vacuum the Absolute? Here Vacuum the Absolute is referred as to God Hole, defined as a state that absolutely isolated from God the Infinite, instead, Dirac Sea is an evolutional fittest one under natural selection from Ldots, which reasonably appeared later than photon after Big Bang in the presence of Field the Spirit (Gn1:2).
when Smolin says "there's a new universe each time there's a black hole in the universe" does he mean black holes come and go
Whenever I see Kip Thorne on the guest list, I know my mind is about to be blown. Black holes contain absolutely nothing, they’re just twisted space and time. Whew! Susskind too, the difference being that Leonard really enjoys fucking with your head.
Isn’t the explanation of Kip Thorne contradicting the scientist later in the video?
One explains that black holes are not made of matter but of warped space and time… the other one explains that they are very dense objects made of matter… which one is closer to the truth?
7:00 I have to say, Doc, that if I should ever cross the event horizon of a black hole, and have the wherewithal to remember to do so, I fully intend to have a bit of fun...Call it Gallows Humor...on my way to...whenever...lol
My plan is to send an outgoing message, in every direction, although I'm now "inside" the BH, and even though...
I know that the only way a person could receive my message would be to have fallen into the same BH as the one into which I fell (ignoring the quantum and relativistic ties, and whatever other wonderful wackiness might apply...work with me here...lol)...
But that's just fine, Doc. In fact, one might say that my plan expects to use this consistency in the known physical laws to the advantage of both myself and (in the way of Napoleon Hill) of anyone else who falls into the same BH as I.
My message will read something along the lines of
"LOOK OUT!! ...JK; JK...Way to fall into a black hole, Dummy!...Lololol"
This way, at least they'll have one last opportunity to laugh, YKWIM?
YKWIM.
😆
Go Bluejays!!
I don't get it. If all matter is detroyed in this process of conversion to a singularity and all that's left is warped space/time then how come black holes have such a huge gravitational pull? Isn't the mass of something giving it such a drag? And what is that something if not matter?
But light doesn’t have mass, how can it be affected by gravity pulling it?
Black holes 🕳 extrude light 💡 out the other center to reform subatomic particles of light into hydrogen
The reason why light can't escape is because the escape velocity from a black hole is higher than the speed of light.
I view all videos of renowned scientists opining about black holes --- to be much like the old tv show "Hollywood Squares", where you could often win by simply saying "I disagree".
lets say that what we imgine
what gives a black hole it's large mass? is there a large mass at the singularity?
It’s a quasar
My brain hurts
What's with repeating all of these interviews over and over again?
All totalitarians repeat rhetoric incessantly
Could the singularity at center of black hole produce inflation into a white hole?
