It took me 3 minutes to feel stupid. I saw like 25 video's about black wholes and i still don't get it.

This video was amazing to me. I never made it past algebra -- not a conceptual problem but actually doing enough work to make it second-nature. So I know that there is no simplification of these issues that accurately describes what is going on. But it is really mindblowing to catch some new tidbit. I'd heard about conservation of information, but never heard any explanation why it had to exist. This video is the first time I heard it explained the way Vafa did here: Information entering a black hole would take with it some nonzero amount of entropy -- and that looks like it would violate a fundamental rule: Entropy must increase, and there can never be a net decrease (outside of random-chance once-in-a-universe anomalous events). Hearing that was like a mindgasm. I know my understanding is superficial at best, but it felt like it took a step forward when Dr. Vafa explained it. The sad part is that I know it's going to be months before I find another lecture/discussion as fascinating as this one was.

What a great presentation! Brian Greene not only insisted his point on String Theory, but Brian made a case that String Theory may be one of the solutions to resolve the mystery of black hole. Cumrun Vafa, I hardly know about speaking in tandem with Brian made several good points about the inside structure of the Black hole. This is obviously a great presentation and excellent video about resolving the mystery of black holes and admire Brian Greene and new the participant Cumrun Vafa as well!

@@fabriziogiordano7396 I wouldn't agree with the phrasing "entropy generates time itself". Time, according to general relativity, is a dimenision like space, existing just by itself. But the thing is that time obviously has a "direction" from past to future, yet in our fundamental laws of physics time has no particular direction, the laws are symmetric under going backwards/forwards in time. Only the second law of thermodynamics, that says entropy always increases, defines a direction, namely the direction in which entropy increases. In that sense increasing entropy defines the direction of the arrow of time. Time dilation describes the fact, that the "speed" at which time passes is in general different for different observers, so for example when you are moving really fast or are close to a gravitating object (like a black hole, or also just the earth).

I think this might be the first time a description of a black hole actually started to make some sense to me. I'm picturing matter going into the singularity where, like a fusion reaction every particle down to the strings and waves are fused thereby creating this crazy gravity well where time stops! Is he suggesting a black hole is what occurs when the energy of every particle down to the string is fused?

Violations of the Laws of Thermodynamics in a black hole suggest that it is a border of the closed system the Laws define. The Laws of Thermodynamics only work completely in the 3rd dimension. The Third dimension is not an isolated system in a blackhole because a blackhole is a conduit, or a fluid transition between the 3rd and 4th dimensions- hence the bending of Space-Time=3rd-Fourth and the violations. Its shape and movement looks like a hypercube (which we cannot see directly) And correct me if I am wrong but is the Higgs Field somewhat a border between the 3rd and 2nd dimensions? Both light and matter seem to disappear at the edges of our reality (3rd dimension). Light and matter maybe become completely different things in the 2nd and Fourth dimensions. Maybe light and matter are only the language of the 3rd dimension? Please correct me if I am wrong for I am merely theorizing what I think I see thru the lens of an outsider to the Physics community. Utterly fascinating though.

Interesting thoughts! However the idea of "dimensions" gets mixed up a bit. A dimension is like a "direction" you can move in, independently of all other dimensions. In our everyday life we know 3 spatial dimensions (up-down, left-right, forward-backward) and 1 time dimension. In general relativity, the theory that describes the (classical) geometry of black holes, space and time are described as one single object, namely 4 dimensional spacetime. The separation into "the 3rd or the 2nd" dimension doesn't really appear here, everything is described as one single 4 dimensional reality. The Higgs field you mention is a field in this 4 dimensional spacetime, so it's an object that simple has a defined value at every point in space and time, and so are light (the electromagnetic field) and matter.

Wow! It was so beautiful.( Actually I think)!!!!!

I have a hypothesis that Dark Matter is not a WIMP, but maybe is a deformation of space-time by which the curvature of space-time ALONE is the cause of the gravitational effect. Gravity is the consequence of the curvature of space-time. It may be possible that the structure of space-time itself could be warped without the presence of mass. Space-time has been shown to react like a fabric by warping, twisting, and propagating independently of mass. These properties have been proven with observations of gravitational lensing, frame dragging, and now gravitational waves. Fabrics can be stretched, pressured, and/or heated to the point of deformation. Such extreme conditions were all present during inflation, so it is plausible that space-time’s elastic nature could have hit its yield point and permanently deformed. Therefore, if gravity is the consequence of the warping of space-time, and fabrics can be permanently deformed, then a deformation could create a gravitational effect independent of mass. DM could be a microscopic imprints or stretch marks like black holes with no mass at the center, but they wouldn't lose their strength via Hawking Radiation because the warped geodesics/fabric is fixed. Prediction: Spacetime's elastic property hits a yield point, so only that part of geodesic's "stretch marks" would remain after inflation stopped. These steep gravitational wells would not follow the inverse square law. They would be steep tiny gravity wells that produce gravitational effects with nothing in them to detect.

Gonna need some tensor calculus and differential geometry thrown in there at the very least - as well as a very deep understanding of quantum & conformal field theory, gauge symmetry, quantum mechanics, and of course all the current models (ΛCDM, for instance) and observations that the theory will have to also explain in order to be even remotely considered by anybody.

Shows that no information will ever be lost because the information will always be available in the event horizon. Easier way to think about it is that it’s an infinite hard drive that will be destroyed.

Seems like a black hole would act more like a recycler than a bit storage machine. Intuitively, I would assume anything that goes into a black hole would lose all its uniqueness and be crushed down to 0s and 1s and then just stacked or grouped together with all the rest of the crushed information. So, yes everything that went into a black hole would be there broken down to its lowest state, but everything would be crushed down so much it would just be like similar bits of recycled info. I think black holes destroy information in this process like recycling aluminum cans. All the materials that made up the variety of cans is there, but broken down and scrambled. There would be just a group of 0s and 1s so you couldn't reconstruct all the individual components that originally went in. The raw material of energy is all there but broken down and recycled so individuality information would be lost.

In some sense the particle that falls into the black holes has another sense of "time" and related to this, another defintion of "energy". You can then think about it, like the particle that falls in has "negative energy" and thereby actually decreases the energy of the black hole. (And of course remember E=mc², so energy and mass are basically the same thing).

If one particle is sucked into the black hole an the other is “radiated” away from the black hole...how is this a loss of energy if be particle is still going into the black hole. Or is the heavier particle getting pushed out? What energy or force is pushing things away from a black hole? I don’t understand how this equates to the black hole losing energy. Not to mention the ungodly amount of gas and other stuff getting pulled in through the regular operation of extreme gravitational pull. Such a huge amount of stuff to cram into a black hole yet it loses energy? Also if a pair of particles are created near the event horizon I don’t understand how one is sucked in and the other is radiated away when essentially they are for arguement sake on the small scale in the same place(relative to the size of the black hole). They should both be sucked in no?

As the even horizon of a black hole expand because of entropy, So does the universe today, at a planck scale, expand because of entropy, So does the universe at the time of the big bang." (Entropy generates time itself) Thank you so much.

Or maybe it's as simple as as change of state. So if there are 11 dimensions or 9 or whatever, why are we describing something as powerful as a black hole in terms of 3 dimensions? The singularity cannot be observed as a 0 point or infinity, beginning or end, it should be calculated as a change of state into the other dimensions that we cannot perceive. The energy does disappear from out 3 physical measurable dimensions because it is transferred to some of the others. The problem is that if we cannot perceive those other dimensions then how can we utilise them? If we can conceptualise them, then we find the answer to time travel & teleportation.

Any object no matter how dense, will resist gravity, so if the singularity fundamentally doesn't have infinite density, then it must have spatial dimensions, and in turn it should fight back against the surface gravity of the black hole. Which should result in an increase of the event horizon's radius as the black hole looses mass, and ultimately to something akin to a supernova at the end of the black hole's lifespan. Why do we still expect black holes to vanish??

Entropy isn’t loss of order, it’s the collection of prior universal patterns’ energy Basically there’s no required order, but there’s always a record of ordered progression along a temporal path, so there’s a general observable pattern to that lack of a pattern I dunno, honestly, quantum mechanics escapes everyone

So if Greene is speaking, how is he watching too? at 0:16 Is it spooky action in the audience?

I have no doubt some of the ideas within string theory are clever, but we await experimental evidence of these strings and dimensions. It seems like you could just keep modifying the theory to fit the observed data. Which sort of implies it is a model, rather than a theory. Interesting though.

I know exactly how black holes are created and how they work. I'm not an Einstein or Hawking, but I've figured this out anyway. How I did this is my secret, but I will explain them. Black holes are creators of galaxies, this much we know for sure. BH's have infintite different sizes and the biggest and strongest are the ones who control entire galaxies of billions of stars. Most all stars explode then reignite and become stronger. A BH that can create galaxies is a super old and many times exploded star. Probably trillion of years old. It's not a singularity, it has a massive form. This is where the periodic table comes in play. At some point the remnant core of this giant, old star contains the heaviest metals in the universe. Very magnetic, super heavy metals are what's left after this final explosion of its life cycle. This final explosion is what starts a galaxy. Trillions of stars will start their life after this explosion. Anything surrounding this explosion will vaporize and help out the creation of new stars surrounding the new BH. The sheer power of the new BH is it's super immense magnetic power it now has. BH,s this size are basically an enormous magnet. If anyone wants more thoughts, please just ask, as it's impossible for me to explain it all in one comment. The periodic table is involved and these materials comprising of the BH will never be discovered by anyone. But how this material is created is a long trillions old cycle of a star.

Can anyone explain to me how a quantum fluctuation, sending a particle into the black hole, leads to the black hole evaporating over time. All I see are particles that weren’t there, appear there, and add a particle to the black hole, and send the other particle out as radiation. Seems like the black hole is just gaining a particle.

Great question! The first thing to realize is that this story of "creating a particle-antiparticle pair, one falls in, one flies out" is just a very rough description of what's really going on, and this analogy can not capture the whole story. However what you could add is this fact that was mentioned also shortly, that at the event horizon, space and time sort of "switch roles". In some sense the particle that falls into the black holes has another sense of "time" and related to this, another defintion of "energy". You can then think about it, like the particle that falls in has "negative energy" and thereby actually decreases the energy of the black hole. (And of course remember E=mc², so energy and mass are basically the same thing).

Yeah, I just asked the same question. Perhaps the answer lies in the entanglement of the two particles, but I can't figure it out past that.

Only for as long as string theory doesn't explain it(patches up the holes). To a great degree, quantum physics are highly incomplete math, merely general estimates. String theory seeks to correct this in a sense.

not buying string theory and its dimensions. Also if entropy increases and the amount of info one needs to describe the system is greater for larger entropies, how much information would we need to describe the universe when all stars are gone?

That's the surprise.

I dont understand why black holes' absorptions are important from the viewpoint of entropy, because afaik absorptions through black holes never finally happen due to the warping of time. So, why not everything fine then from the perspective of entropy?

@BuhuBaha

3 жыл бұрын

Oh absorptions certainly do happen. If you fall into a black hole you will cross the horizon and fall towards the singularity in a finite amount of time. It's just that from the outside we can never see anything cross the horizon, because (by defintion) we cannot see past the "edge", the event horizon, and it looks like nothing ever crosses the horizon. This is however only due to our outside perspective, from a "birds eye" perspective we can completely track the infall of stuff across the horizon.

If you stand on the ground and watch the plane fly across the sky, you can only see it when it's right above you, but not when it's on the other side of the globe (it's "behind the horizon"). However, on a world map you could track the whole path of the plane without problems. It's just a matter of perspective.

but if the black hole emmits particles dont these particles have information? And if the black hole evaporates by emmitting particles, isnt the information restored in a different way? Im stupid, sorry. Its counterintuitive the whole thing

Because quantum foam continually creates pairs of particles and anti-particles. They're called virtual particles. But near the surface of a black hole the theory is the anti- particle is captured and its counterpart particle flys off. That's all I know.

I had a similar thought about teleporting people. You would compress the information in the person to transmit them quickly through the teleporter. Think about the same way you zip up large files for email. So then would the "file size" of the human depend on how complex they were as a person? :) Einstein wouldn't shrink much, but I would zip down to maybe a gigabyte! And then depending on the baud rate of transmission, there would be a time to transmit the "zip file" of a person down the wire to the destination teleport decoder. So if the file is large (person is complex) it would take longer. If the teleport distance is small, it might be faster to walk to the destination than teleport there *depending on the file size*. So QED: in the future stupid people won't have to walk as far as intelligent people; they'll just teleport. Enough :)
