Steven Hawking never proved that they actually exsisted.

What if the ejection from a black hole is actually a blast from a new big bang of a new universe being created? Eventually it closes itself off leaving nothing but cosmic radiation, which would be that universes dark ages (around 3800,000 years after the big bang). Some universes would make it. Maybe every black hole is a universe generator. Maybe I'm smoking too much.

Abhas Mitra Indian Scientist already 10 years ago before Hawking reveal, he told that Black Hole Doesn't exist. It's not any achievement has done by Hawking

I am submitting this question for the second time(first here). If you were to enter a black hole below the event horizon, could this possibly be a form of entering into a time warp/wormhole? May be a silly question which has no merit.

rule 1: there is a black hole rule 2: everything goes in, nothing comes out rule 3: it keeps sucking and sucking rule 4: it will grow questions if it kees growing - how big will it be in 1000 years, 2000 years if it has been growing, how strong will the black hole be and will this result in accelleration of the process.. if this was true.. why are we here.. and not sucked up.. by a blackhole ? So, the blackhole must leak and fade .. in a curved morgage model aka, it will be losing more and more mass in time.. slowing down the effect of the "apparent" horizon.. and then.. will it become a star..or.. a scar ? up,down, equal - it can grow due to added information it can shrink by losing information it can stay the same - but why ? the escaped data.. is : mangled data - not in the format as it wend in ? from initial escape point the laws of physics apply ? very elementary particles fuse to the next level of weight ? new elements are created ? is the escaped matter radio active ? will it decay fast, moderate, slow ? will it do fast, moderate and slow in some specific spread spectrum ? will the escaped stream trigger the creation of stars ?
elgato9o (5 months ago)
but if black holes lose matter and therefore mass over time, if after some million of years it has lost enough mass that it's gravity is no longer strong enough to absorb ALL light then wouldn't it slowly devolve into some sort of dead star matter that a future human can observe?

God says in the holy Quran what means [So verily, I swear by the stars that are veiled . And by the (sweeping ) stars that move swiftly and hide themselves. And by the night as it departs; And by the dawn as it brightens; Verily, this is the Word (this Qur'an brought by) a most honorable messenger [Jibril (Gabriel), from Allah to the Prophet Muhammad (Peace be upon him)].] (chapter At-Takwir: verses 15-19)

As I understand it, black holes evaporate, which is where Hawking Radiation comes from. It’s basically “steam” from all that matter being compressed into a teeny point. Once the black hole has run out of fuel, it stops emitting Hawking Radiation, the event horizon dissipates, and all that is left is... we don’t know yet. Ash? A diamond-like particle of super compressed matter? But it’s not lost, only changed. Basically, Hawking said that black holes are temporary, not eternal. They’re more like a forest fire that is deadly but not forever.

Greg Lives25 minutes ago.Since we live in virtual reality, huge forces are just data;  universe is being run by super computers that convert data into our physical world & back to data, both at the event horizon.  The event horizon is your 2D holographic medium. Physicists (Hawking) conjecture that things that fall into black hole are extinguished while data (info of the matter) is left on event horizon.  Conjecture- event horizon is  like holographic film  A super dude is creating these holes with computer like device, but since he isn't IN the universe,  he is using DATA( in a computer ) which create virtual forces, virtual matter & virtual beings (US) after passing through the event horizon.  He is also removing/destroying things via black hole (which converts into computer code- 1s & 0s). Some info stored on event horizon, other info saved somewhere in superdudes computer.  If you are creating a virtual reality, those 1,000,000 degrees of heat in suns in our reality has no intrinsic value to the maker other than code. At black hole code applied to  event horizon= virtual creation;  Matter/forces of our reality sucked in at event horizon are broken back into code.  To superdude it is just numbers- ( furious winds in video games are just numbers in a computer. When you play video, are you ever effected by anything in the game like a video character is?- NO. No Thor Hammer or Panzer tank can touch you.  Work this concept.     Here's a stumper. All people see everything their whole life  in small area at the back of brain. What theorists are saying "the wave functions are collapsed by observing, which solidifies the object" in the outside world. But does it. Where do physicists make these measurements? Where is this "outside" world? In A building called university or are they all in their own little visual cortex where things aren't outside of anybody. Everyone collapses wave function in the brain, but you are tricked into believing it's outside your body.  Here is scenario- physicists  all seem to be going to work; working projects, making measurements on experiments, but it's an illusion. No one leave a spot, because no spot actually exists- all illusion. So, observers aren't collapsing waves outside of them, but the waves inside their head which solidifies their "reality"; a reality which seems to be shared with other beings- connected visual cortex to visual cortex in some manner. Is there an outside world? Seems not. Everything can happen in each person's visual cortex which gives the illusion you are seeing outside yourself. `

I think black holes create dark matter via massive gravity pressure in them, and then they radiate dark matter into space.

1st, the idea that black holes have an infinitely small singularity of an infinite mass should had caused mass-puking in the schientific comunity from the early 60s. It starts from a finite ammount of mass (a star), gulps a bit more along the way and that‘s that. No infinity. Big, yes, not that big. 2nd, obviously there are no black holes. Because it would be a pleonasm and racist.

THERE IS SIMILARITY BETWEEN BLACK HOLE AND MATTER. If a photon emerges when a positron and an electron collide, it means that the electron and the positron are formed by means of an "oscillation trap" which does not allow the photon to escape like a black hole. In this case, there is a functional similarity between an electron and a black hole. There may be a structural similarity between black hole and matter. Why do not physicists think it? If the only thing that is not an antiparticle is photon, does not it mean that this photon is the most massive building stone? Everything be consist of different oscillation of photon. An interpretation of Einstain equation for E = m.c ^ 2 tells us that everything has come to light. In this caseIs matter acctually a formation of black hole in a sense?

So if hawking was proposing that the apparent horizon will evaporate when the black hole radiates out all of its energy. Wouldn't that leave the possibility that a very long time ago all black holes came together and when it radiated away the big bang happened?

I read a remarkably clever SF story, in "Analog" magazine I think, in which a future nuclear fusion power plant, using some ferocious heavy hydrogen compression mechanism, creates a small Black Hole. The reporter goes to the best qualified physics professor he knows, and they conclude that a Black Hole will eat its way to the center of the planet, and go on eating. It's the End of the World! The reporter files his story electronically, and remembers he didn't answer the question "When?" He goes back the the professor, who has also been thinking about it, and this story having been written not very long after Hawking published his conclusions about the relationship between the mass and the lifetime of a Black Hole, it turns out that any Black Hole of the mass of the entire Earth would be very evanescent. Should the reporter be consoled for the ignominy that his greatest story ever is false, by the fact that the End of the World actually hasn't arrived?

Wait. If a black hole condenses matter into an infinitely small point, wouldn't that be 1 dimensional? And we live in a 3 dimensional universe, which makes a 1 dimensional object, the black hole, physically impossible. I'm no scientist, and would love if someone who actually knows what they're talking about to correct me.

Blackholes r just ultra dense & ultra hot things period. Just like base of oceans r ultra high pressure. Interestingly if u put solid objects at base of ocean their volumes indeed decrease ie their densities increse. Just extrapolate this phenomenon & u get blackholes. They r no mysteries.
