The Big Bang, Black Holes and points of infinite density ...?

Question

If I understand correctly, at the base of black holes are points of infinite density. The big bang, as I understand it, originated from a point of infinite density.

If I understand these things correctly, is it not theoretically possible that our universe is the result of a black hole? And that other universes, possibly behind our means of observation, are being created as a result of the black holes which we know to exist?

My apologies to the astrophysicists to whom this question may seem elementary (or elementarily flawed)!

Any insight would be GREATLY appreciated!

Answer 1

These questions have not been answered, but there is general agreement that the infinite densities (singularities) predicted by general relativity for black holes are not real, and that the theory breaks down at some point. The theory also shows that all such singularities are protected by the "event horizon" which prevents any transfer of information from inside the black hole. It is expected that the incorporation of quantum theory will avoid the problem of the singularity, but so far there has been no successful combination of general relativity and quantum theory.

Answer 2

The equations of General Relativity allow for singularities: points of infinite density.

Just because two solutions to the equations both have singularites does not mean they are similar solutions, or that (as you suggest when you say the BB could result from BH) you can topologically identify the two singularities and get a coherent dynamical solution. There is no reason to believe a BH would evolve any further, into anything else.

We know that our theories of physics are incomplete, in the sense that the singularities present in General Relativity are forbidden by the Quantum Mechanics. It is likely that the pure singularities of General Relativity will disappear with better, more unified theories of physics.

Answer 3

As per the 2nd law of thermodynamics Mass structures have the Tendency to decay,no matter how fast their obital motion .
Black holes are thought by Cosmologists as mass structures which have a diameter as defined by Schwartzchild. The more massive the blackhole structure the less dense it becomes. Therefore if a Blackhole mass would increase with time to a quantity as near an undefinable one which we call infinity,the Density of the black hole would actually approach a density which would be trillions a trillions of times smaller than the density of air. That Means a very massive black hole as per Schwartzchild calculation based on the solution of the General Relativity Field equation would have a very near zero density.

By experiments and observation ,the density of the Universe is aprox. 7 x10^-26 kilograms per meter cube.
This fits into the Definition of a large mass of which no light can escape yet it has a very low density. In that sense the Universe could be considered to be a large Black Hole that exists somewhere in our Creator's Heaven.

However; in the world of atomic structures, the Neutron has a density which is equal to approx.51 x 10^15 kilograms per meter cube. And the density of one foton is approx.2x10^53 kilograms per meter cube.
Therefore it appears scientifically that the density of one tiny tiny partcle of light is many folds denser than the density of any Black Holes which are defined by the Singularity Theory.

No need to apologize .Your question was very scientifically innovative.

Answer 4

I have never heard of this infinite mass in a blackhole theory before, it sounds stupid to me. There is a finite mass to the universe. If you add the energy and matter together the universe remains constant (as far as we know). Space is expanding but matter and energy stays the same. Like I say, Maybe Infinite is just Finite beyond our Comprehension!

Answer 5

the theory of BB is it self flawed one- so where is the case of infinite density and black hole ?
centete is correct ther term infinity is just an imagination.
every thin is finite in this universe, including the universe it self.
the universe did never originated from BB. BB is not at all possible just keep a bomb will it explode. so what did cause the big bang ?

Answer 6

There is actually NO SUCH thing as infinity or infinite anything. It is a mathematical tool and has no meaning in reality.
E.G. What is infinity +1?
What is one half of infinity?

These are nonsense questions because the reality of an infinite is a nonsense, just like the square root of minus one.
They are handy mathematical tools but that is all.

Answer 7

yes it is possible.they say that whatever is absorbed by a blck comes out of it through the other end,though there are many contradictions to that.also once scientists had proved that black holes do not exist at all but again recenthly they have started research on black holes.

Answer 8

yes, this is actually a big theory in astronomy. the only question is if space can separate from a part of itself. if it can then this theory makes the most sense out of all of them that ive heard.
