Why Don't We Live Inside a Black Hole?

In summary: Additionally, the universe is not a closed system, so it would not have the conditions necessary for a black hole to form.

We know the Big Bang Theory states that our universe was started from a hot-dense point. But should't it became black hole and every matter and radiation pulled to singularity? We would not be her if that is the case.

It is unfortunate that you "know" that, since it's not true.

The "Big Bang Theory" doesn't actually say anything about how the universe started. That is, that theory does not posit a creation event. It posits a starting universe in a hot dense state, which may have been infinite in extent or may have been finite, but if finite, it was not a single point in space. That plasma state evolved into the universe we live in today.

I suggest a forum search. the question has been answered here dozens of times as to why we don't live in a black hole.

A black hole is a vacuum spacetime. The Big Bang is based on a spacetime with matter everywhere. They are not equivalent.

No. The matter and radiation in the early universe was expanding very rapidly. Far too rapidly for any of it to collapse to a black hole, even at the very high densities of the early universe.

Related to Why Don't We Live Inside a Black Hole?

1. Why can't we live inside a black hole?

Living inside a black hole is not possible because the extreme gravitational force inside a black hole would crush any form of matter, including human beings.

2. Can anything escape a black hole?

No, nothing can escape a black hole once it has passed the event horizon, which is the point of no return. This includes light and even electromagnetic radiation.

3. What would happen if we were to enter a black hole?

If we were to enter a black hole, we would experience a phenomenon known as spaghettification, where the extreme gravitational force would stretch and pull our bodies apart until we are torn apart into individual atoms.

4. Are there any known black holes that we could potentially live inside?

No, all known black holes are too small and have too much gravitational force for any form of life to survive inside of them. Additionally, the intense radiation and lack of light inside a black hole would make it impossible for life to exist.

5. Is it possible for a black hole to explode?

While it is not possible for a black hole to explode in the traditional sense, they can release massive amounts of energy through processes such as Hawking radiation and accretion disks. This energy release can sometimes be seen as a powerful burst of gamma rays, known as a gamma ray burst.
