Why would the mass from the Big Bang explode instead of simply forming a black hole?

Question

There are black holes at the center of galaxies with millions of solar masses and they don't explode, in fact just the opposite. Why would an even bigger mass explode?

Answer 1

It is easy to visualize the Big Bang as an explosion, but that is not quite correct. It is the space between the matter that expanded, and is expanding still. The four forces of the universe -- gravity, electromagnetism, the strong nuclear force, and the weak nuclear force, were theoretically the same at the time of the Big Bang, so gravity (the thing that causes black holes) was on an equal footing with light and the nuclear energies. It is when this symmetry broke that the forces each went their own way with their own peculiar characteristics. The high energy physics of the early universe is well understood and there are many books and scientific journals that explain what was going on in those first few seconds of our universe. The short answer is that the force of the expansion of the universe overwhelmed the pull of gravity. In fact, it still does, since the universe is still expanding.

Answer 2

Big Bang is still just a theory, a very tested and sound theory. No one can answer this question in it's entirety. The major difference between galactic black holes and the singularity proposed by Big Bang theory is mass. Sure a galactic black hole has millions of solar masses but the singularity that started everything had the entire universe (plus anti-matter) packed into an infinite density. Big difference.

Answer 3

First of all, the Big Bang itself is an explosion of great mass of matter. Second, the reason why after the explosion the mass of matter does not form a black hole (unlike the mass of matter from a supernova which forms a black hole) is that the explosion is too great, imagine, the entire universe exploding. The outward forces of the explosion exceeds that of the inward pull of the gravity.
But as time pass, soon the outward forces of the big bang will soon be cancelled and defeated by the inward pull of gravity. Then, the universe would not be expanding, but instead it will b compressing. Until it forms something just like a black hole, but much big, a universal black hole.
Then there will be another big bang and all over again...and again.

(note: currently scientists say there might not be a force of gravity great enough to pull all the matter of the universe back into a universal black hole again, meaning, the universe might just keep be expanding. but i think it's unlikely.)

Answer 4

It didn't explode. It expanded.

And we don't know, yet. But the laws of physics just break down when you get inside a black hole - and if you've got one with all the mass in the universe inside, who knows what could happen?

Answer 5

i think of this question is greater of a hen or the Egg question. that is already time-venerated that each and each great galaxy has a "supermassive" black hollow at its center. From this you'll additionally come to a end/wager that the full Universe might revolve around the same variety of a black hollow. that is impossible although to declare whether the enormous Bang develop into the "wind" from the black hollow formation or the Black hollow develop into formed via the enormous bang.

Answer 6

I would say that before the Universe existed and it was all a small ball of superheated massive pressured matter, this itself could've been a blackhole. Blackholes themselves can blow matter out in massive explosions. Who is to say that the Universe wasn't one of these blackholes that had that same type of explosion of matter.

Answer 7

well we weren't here for that but we can see white dwarfs turn into a supernova which is the same process. the star collapses and it can't handle the pressure of itself so it undergoes carbon detonation
