Dr. Vivian Robinson pinpointed math mistake that led to theoretical Black Holes. Event horizon does not exist actually - it appeared due to a simple math blunder. "Nearly Black Holes" - term introduced by Eric Lerner, plasma physicist, - exist: they have magnetic field like normal or neutron stars have, and have strong time dilation around - that burns cosmic rays and particles, and other things explained in my Time Matters. As for "light cannot escape" see chapter 1 on Snell's law. Chapter 11 explains radiation around nearly black holes, around/in galaxy centers/bulges, what is going on in Fermilab.

It still seems to be a Misnomer to call Ultra compressed matter, energy, and space time a 'hole'. If all things are eventually sucked into one super sized black hole, you basically get the infinite point of all energy at the start of the Big Bang. And perhaps POP! it all just happens all over again.

3:46 I have a small question about this: In real life, as a black hole gets more mass, its event horizon expands; so in such a case, will the distant observer see the falling object crossing the expanding event horizon slowly, or would they see the object slowing moving outward with the expanding event horizon?

@GuRuGeorge03

yes but in the newly formed gaps, caused by the further expansion, caused by the new mass falling into the black hole, there is the new information (or image/pucture) of said mass. long story short: as with anything black hole related, the reality of it is much more complicated than other oversimplified model can show. e.g. most blackholes aren't perfect spheres + they spin extremely fast + other weird effects.

Very good explanation. Indeed, one of the most important, defining characteristics of any generic ( subextremal) black hole is that the spacetime geometry is dynamical in their evergrowing interior, even for those black holes that are relatively isolated ( and so approximately stationary, from the " outside" perspective) for some period of time. Only a bit of nitpicking: The singularity, generically, is spacelike, so the statement that it is at the spatial center of the hole it is not exactly correct. The region near R= 0 can be considered as the spatial center of the collapsing star only before the singularity appears. After the " birth" of the black hole, the region in the vicinity of R= 0 where the curvature grows without bound is akin to a spacelike surface, so the singularity, according to classical General Relativity is, in a sense, the future endpoint of the trajectory of anything that falls in. It's just a consequence of the fact that the growth of the tidal forces / curvature inside the horizon is time dependent.

Finally somebody did a video representation with the space grid in time! I have a question: there are 4 regions where the grid looks a lot more scarce than it is in other areas (on diagonals of some sort) - is this a limitation of the visualisation, some kind of aliasing, or is it how the space is curved in reality too? And the second question: each white dot of the grid gets really curved as it gets closer to the singularity - so is it a "pixel" of space that gets curved like this or is it the object in the space that gets curved?

@EugeneKhutoryansky

@GRIFF2016

@@EugeneKhutoryansky I think the base answer of space-time becoming curved would help answer that both the "pixel", or better described as differential element, in that point of space time becoming curved would result in any object which enters into this new element or "pixel" would conform to the physics of that point. Thinking in larger perspective would presume an object that exists in greater area than the element would see its own changing curvature as the physics influencing the object would cause the matter of the object to conform the physics of each point it exists, causing the object itself to curve. This would even be true on earth, as every differential point on an object is subject to different magnitudes of forces, but in a blackhole everything is extremely magnified. This really only holds up to a point to where the gravitational forces and influence of radiation would allow the bonds to still exist, as the object would no longer become an object, but breakdown into its base components. This is just my 2 cents at 5am, but I think the logic is mildly sound without getting into overly complicated physics in a comment and having to bring high level mathematics and physics theory into it.

spacetime close to a black hole is so warped that - every spatial direction points more and more towards the center of the black hole, till every direction points to the inside. - the time-dimension gets shorter and shorter (the speed of time slows town to a near-stop) When the black hole spins (fast enough), this area is surrounded by a more turbulent ergosphere, with more turbulent spacetime arrows, that can be "sailed" trough and escaped (with a lot of good timing and energy use), and that can theoretically be used to throw mass into the black hole in a close flyby through the ergosphere to gain a LOT of momentum AWAY from the black hole (and easily reaching escape velocity)

as far as I know time and space switches places in the black hole so the singularity is not a location but an event. and black holes evaporate in time and time slows down so by the time anything reaches the event horizont so much time passes that the black hole is not there so there is no inside of a black hole.

An object on the event horizon does not “appear frozen” to us. As the object approaches the horizon, not only the photons it emits are more and more redshifted, but fewer and fewer photons per time unit manage to reach us. So the object not only appears redder and slower, but also darker, and when it’s sufficiently near the horizon it doesn’t “freeze” - rather it disappears, as we are unable to detect any signal coming from it. Apart from this, excellent work!

About 01:35f: _People often refere to the size of the sphere as the size of the black hole even though all it's mass is concentrated in the center._ I also do so because it's called a "hole" which contrasts with the idea of a "solid body". Whereas the latter has a more or less hard surface, a hole lacks one, and this is why I don't refer to the central "body" as the black hole but to the inner region of it's gravitational field where the radial coordinate is timelike.

Great vid. When people talk about length contraction they forget that it actually describes a full x,y,z compression of space, so the aperture of a black hole is in fact the exact size of the mass below, but the aperture is expanded hence the funnel like curves, this is true for atoms as well, twice the Temperature is twice the compression, therefore the "deeper" mass "appears" half the size , but it is in fact going straight down on all sides. So no "singularity" either, the weight is just point temperatures of the mass expressing Gravity for it's temperature in the weight space and consuming massive amounts of space, which is compressing into the aperture of the black hole to feed the mass/temperature creating the mass. i.e. it's not really curved it just looks like it because of time dilated or compressed space physics.

I did not realize that it was spacetime itself that was falling into the black hole. Now I wonder if when we see the universe expand, if looked at from another perspective, it could be the average of all spacetime falling into all existing balck holes? So, the universe would be expanding into black holes, and since there are so many of them, and they are scattered all throughout the universe, it could look like either the universe is expanding, or the universe is falling into its black holes. The universe expanding and contracting infinitely and simultaneously. ?

@dimitrispapadimitriou5622

The expansion of the universe as a whole happens with the same rate everywhere at any given " moment" of its cosmic history, and its acceleration due to the cosmological constant seems to be the same also wherever we look. Our universe is approximately homogeneous and isotropic, at least when we're talking about very big scales. It's not the same with black holes: The spacetime geometry of a collapsing star that forms a black hole is not isotropic. The curvature and the tidal forces grow as one comes closer, and inside the horizon they become time dependent, so everything that falls in is doomed. The interior of any black hole is indeed growing, so that older black holes have larger interiors, but this expansion is very different from the expansion of the universe.
