Could the Big Bang Have Created a Black Hole?

[mangog]

I've always wondered about this...if one sun over a certain size is enough (at the end of it's life) to become a black hole, then at the big bang, ALL the matter in the universe was in a very small space...so my question is why wasn't the big bang enough to actually create a black hole itself? Or maybe the big bang could be not a "big bang", but instead matter streaming into a black hole in a different universe and creating ours as it entered...

I have no idea, and I'm no scientist, but I am extremely fascinated by cosmology. I'm very open and eager to read answers to this - many thanks in advance

tl;dr, the universe didn't happen inside another universe.Additionally, a black hole would probably require a more defined separation between gravity and the other forces, while most models suggest there was little if any such difference, with many models suggesting that all four forces become a single superforce at extremely high temperatures/energy densities.

The way I think of it is this. Whether this is right or not I dunno.

At the big bang the universe was packed with extreme density. But it appears that the distribution of the mass was almost homogenous, that is, there was almost exactly as much mass at point A as at point B. So gravity almost cancels out everywhere.

Another way to look at it is to have a black hole you have to have some place with less gravity than there is in the black hole. In the early Universe there was no such thing. There was no empty space whatsoever for a long time.

Now I said gravity almost cancels out. So there could be black holes left over from the old days from regions that had a little bit more density. A search is in progress, no luck as yet.

Extremely overdense regions in the very early universe would have stood out like a sore thumb in WMAP.

I can understand your curiosity about living inside a black hole and the potential connections to the Big Bang. However, it's important to clarify that living inside a black hole is currently not possible according to our current understanding of physics. The intense gravitational pull and distortion of space and time within a black hole make it an inhospitable environment for life as we know it.

Regarding your question about the Big Bang and black holes, it's important to note that the Big Bang was not a single point in space but rather an expansion of space itself. The matter and energy in the universe were not compressed into a single point, but rather spread out over a vast expanse. This is different from a black hole, where all the matter is concentrated in a single point. Additionally, the Big Bang did not have enough density to create a black hole. The universe was expanding too quickly for the matter to collapse into a black hole.

As for the idea of the Big Bang being the result of matter streaming into a black hole from another universe, it is an interesting concept but not supported by current scientific evidence. The Big Bang theory is the most widely accepted explanation for the origin of our universe, supported by observations and calculations from various fields of science.

Overall, while there is still much we don't know about the universe and its origins, we can continue to explore and learn more through scientific research and advancements in technology. Thank you for your interest in cosmology, and I hope this response has provided some insight into your questions.
