[@toniroberts8117]

He is very good at using simple analogies to help explain complicated phenomena, but it’s important to remember he is over simplifying these concepts. Understanding it fully is much more complicated often requiring mathematical equations to really grasp the concepts. My father was a genius and studied astrophysics and relativity theory, but he studied it using mathematics (calculus and geometry). I was never good at the math but studied these concepts from reading theoretical physics (with little math) and it was really difficult for my father and I to discuss these theories and agree on concepts.

[@101perspective]

If nothing can escape a black hole then where does the spin energy come from? Also, if we are seeing spinning close to the speed of light then doesn't that mean that it's actually spinning significantly faster than the speed of light once you factor in the slowing of time as you get close to the black hole? I mean, if you got closer to the black hole you would see the spin increasing well beyond the speed of light wouldn't you?

[@Anthony-ym6iz]

So, if the mass collapses and disappears, leaving behind warped space time, why doesn't it snap back once the mass has gone. Also, if black holes move and rotate, what is it that is moving and rotating?

All this is elementary astrophysics known for very long. What would be of more interest is if he discussed the singularity, which is a ring in the Kerr case and not a point. If time flows towards it, what would a comoving observer see? A transport into the infinite future?

[@sinebar]

Beyond the event horizon all the possible futures point toward the black hole. It's not that you can't escape a black hole but that you won't.

[@Matlockization]

Is the gravitational force weakest at the poles of a black hole ?

[@brightestdarkness7882]

Matlockization I wouldn’t expect that to be the case, right?

[@patjohn775]

For a spinning black hole gravity is less at the poles if you are comparing the gravity at a particular altitude relative to the black holes center of mass. We know this for sure because the event horizon is an ellipsoid for spinning black holes.

[@tabansteintv]

I was under the impression that we didn't know whats at the center of a black hole. Yet Kip Thorne in several occasions mentioned that all the matter is destroyed inside the black hole leaving an object made up of only warped space time. Is this correct?

[@tabansteintv]

As a follow up. How can the destruction of an object create a black hole allowing for the warping of space time to continue without anything at its center causing the gravitational pull?

If time runs faster outside the event horizon of a black hole than it does inside the black hole, Hawking radiation would evaporate the black hole before enough time has passed inside the black hole for such an event to have occurred. So how is it that a black hole could experience two frames of reference at the same time? There seems to be a real paradox here. If an observer inside a black hole looking out could survive long enough, could she witness hawking radiation evaporate the black hole before enough time in her frame of reference passed for the evaporation to occur?

[@reginaldbauer5243]

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? If there is no radiation emitted by the black hole, then what are the astrophysical jets that come from the black hole? (1) What is space expanding into? (2) What is time? (3) Where does spacetime come from? (4) Why was the universe born hot and dense to begin with?

Do objects passing the horizon become stretched from matter at the horizon to energy inside black hole?

[@chrisgriffith1573]

Making a pseudo "water wheel" for a black hole, would take more resources and energy to keep in place than what energies you might drive from it. You might find a sort of Lagrange Point for a self sustaining orbit which derives energy for keeping such a close orbit... but I doubt the energy could do more than offset the energy necessary to keep orbit.

but they do not go that fast ever, the laws of nature apply to it it spins NEAR the speed of light not AT it, so time would be dilated extremely but not stopped. your perspective its been said time would but you would be torn to shreads and smeared all across a singularity.

How come the matter falling straight down into the black hole do not steal the rotating momentum of the black hole? I get the object that once turned into a black hole rotated, but when it 'eat' matter, that matter must loose it's rotating momentum already when it enters the event horizon, falling straight down, and eventually make the black hole stop rotating?

[@Debonair.Aristocrat]

If I'm near the horizon looking out, seeing everything moving faster, would I see light moving faster than the speed of light? And what does time do around White Holes?

[@johnyman13]

I suppose light woul still have the same speed because it's relates to time?

[@dlevi67]

Not according to General Relativity; light would keep moving at the same speed from your point of view (and nothing else would move faster than light either; you would simply see the speed of everything approach the speed of light). (Space)Time around white holes (if they exist) would also be strongly curved; one possible solution is symmetrical to a Schwarzschild or Kerr black hole, just "in reverse", i.e. time would run incredibly fast near the white hole, as seen from an outside observer: particles ejected from the white hole horizon would seem to come from infinitely far into the past (just as particles falling into a black hole would seem to take infinitely far into the future to reach the horizon)

So if you're almost at the horizon and you're watching your space ship friend age, what about if you found a way to push away from near the horizon and revisit him? Does that mean you would be pretty much the same whilst your friend is pushing a Zimmer frame after what felt like seconds/minutes to you?

[@jamiboothe]

So we have these jets we can measure, and we have an understanding of matter, which includes very elaborate time scales and processes that describes the build up and tear down of said matter. Then, we have GR which will define how quickly and in what manor the matter will behave, or be digested by the black hole. I suspect the size of the black hole will be a factor in how quickly the matter that falls into the hole will be digested or repealed by the process. Can we have a black hole that feeds but is undetected by some detector that is out side the horizon?

[@caveyful]

If the rotation could theoretically reach a fraction of c an observation made from outside would appear to be slowed by time dilation such that any measurement of it's rotation would be reduced

Time is a measurement. A black hole will not increase or slow down your biological clock. Light takes time to travel the distance to an observer. Gravity and matter are the fundamental players, but to observe gravities effect on matter will take time for light to travel the distance depending how far the observer and how gravity might interact with the light if there is any light to see.

[@christinathatch2949]

I have a question that I hope someone can answer. He said that near a black hole, two people wpuld experience time dilation relative to one another: one would see the other as moving very fast in time and the other would see the one moving very slowly although they would both feel normal respective to their relative space, yet in another video he said that two people traveling across space at two different speeds would see each other moving very slowly although they would feel normal? Is this a difference in general relativity and special relativity respectfully? If so, is this also the idea and concept behind the theory of quantum gravity? Because particles seem to move quickly in time? I would imagine that if the two people in the black hole scenario could talk to one another, for the arguments sake, that the one circling above and moving quickly through time would have to wait for the person falling in to finish their sentence because they would be speaking so slowly, while yet the person falling in would hear the person up top replying to things they haven't said yet. This allegedly has been observed in quantum physics with particles like the double slit experiment? Is this a time dilation that general relativity can explain?

Is that what makes a galaxy a spiral; the warping of space around a super massive black hole?

[@RT710.]

I don’t think so. The rotation of galaxies comes from the aggregate angular momentum of the massive glass cloud that formed the galaxy. Similar to why a star like the sun spins, but on the level of a galaxy.

[@Hpatrik]

I always imagined singularity as an small extremely dense object (sphere if you will), much more dense than neutron star is. But according to this Kip's description, there is no matter in it because it was destroyed by the singularity, which doesnt make sense to me. There has to be matter in singularity, because matter = gravity.

[@chrisgriffith1573]

We don't know that a black hole has anything going on inside of the event horizon. But what we do know is that radiation, light rays of of any wavelength, cannot escape the event horizon, which only means that within the event horizon, all light that fall onto the black hole will undoubtedly cause a grand display of blinding light just inside the horizon, because of the light pulled in and trapped into a decaying orbit to the center of the hole. If there were radiation emitted by the core of the black hole, then this would not leave the physical surface of the singularity, time and gravity would prevent it. This means two things, though the black hole will not let any motion out possible, the temperature just inside of the event horizon must rise due to all of the radiation being concentrated into an orbit within the event horizon. We see the same thing outside the horizon in the form of an accession disk.

Why would a simulation of the sophistication required use such crude analogies? Not trying to put you down, but don't you think that a civilisation capable of simulating entire universes would use different tools? It's not like black holes disappear, BTW - they are still very much there; they simply don't emit or reflect any light - even though an totally orthodox interpretation of GR (as Kip Thorne is presenting) would say that the matter making up the star disappears, its effects on spacetime remain.
