Black hole appears when spacetime is curved too much. For that you need a density gradient, but there wasnt a gradient in the early universe because whole spacetime was filled with stuff homogenously.

>the actual radius of the Universe is.?

That is not knowable. We can know the radius of the "observable" universe, but the actual universe may be vastly larger. Imagine floating on a boat in the ocean, you can see to the horizon, but you have no idea how far the ocean goes on past that.

Also, observable would be a relative thing. Someone 10 billion light years away could see stuff that we can't, and vice-verse.

All energy was in a hot dense space, not matter. Also, black holes aren't formed by getting enough mass together. If you were to be crushed small enough, you'd be a black hole. If your spoon was crushed small enough, it would be a black hole.

>Why isn't the whole universe a black hole?
It is.
The computer that runs reality is a singularity of literally zero diameter, OR infinite diameter. It just so happens that when you go to describe that shape you are left with the same whether you describe it from the small end or the large end.
All of this stems from the FACT that you cannot create space, because there is no where to put it. You can however PERFECTLY simulate space. So when people ask things like how big is the universe? It's silly. That's like asking, how big is Super Mario Land?
Well, you can SIMULATE it as any size, but the information representing that simulation takes up no space. The singularity/Black hole didn't collapse or form. Talking about it as having a beginning and an end is silly a well. It doesn't need a beginning or and end because it's just true. It's always true.

No answer, there never will be one either

Your weak attempt to debunk a theory shows your basic misunderstanding of the word "theory"

A theory is something which can't be proven - this is all

The big bang theory will never be proven or disproven, it is merely the basis for further discussion of deeper things

Nothing more to say

Consider for simplicity's sake: Once everything has "stopped" the only active force left is gravity. It may take a long time, but eventually everything will drift back together, clump, collapse, etc.

>>5520629
Similar to above. Consider for simplicity sake, that all matter, black holes, neutron stars, whatever, all attract another when there is no other force. The black holes eat all the normal matter, and eventually combine into supermassive black holes, ongoing until only one, singular hypermassive black hole remains. As it collapses within itself, it spews matter back through a white whole, within some other membrane of the universe. The cycle starts again.

Fuck your grammar and your faggot misrepresentation.

A theory is something THAT has not been tested in such a way as to produce consistent results that affirm the initial predictions of the hypothesis.

>> No.5522396

there's this hypothesis that the big bang is the result of an entire universe being sucked into a black hole and spat out of a white hole
