Can someone explain to me what is a black hole in space

explain to me what a black hole is?

it's actually a region of space having a gravitational field so intense that no matter or radiation can escape. very interesting stuff. i suggest you read hawkings 'a brief history of time'. A VERY interesting read. I'll upload it here quick for u i have a .epub of it for my kindle.

here u go man

Theoretically, it is basically a point in space where gravity is so intense that it bends space and sucks everything into it, including light. According to scientists, anything with mass bends space a little bit, but a black hole has so much gravitational force that it bends it to a huge extent. Black holes are theoretical, but there is evidence for them... we just can't see them because, well, they suck everything in, including light.

That's what I learned in a documentary I watched in my physics class.

A black hole is basically a point in space with a massive amount of gravity. Think of it like a tiny sphere with lots of attractive force.

I think one theory behind this phenomenon is that the center of a black hole is at absolute zero or -273 degrees Celsius. At that temperature, all the extra space around and inside atoms completely collapses. That ultra high density accounts for the black hole's gravity.

Black holes exist only in somebody's imagination. The basis of the theory is an assumption that a body can collapse under its own gravitation. One exercise in PHYSICS 101 is to integrate the gravitation inside a sphere. If it is hollow there is no net gravitation anywhere inside. If it is solid then gravitation gets lower as you approach the center, and at the center it is zero. Isaac Newton was the first to point out these things. In real life gravitation depends a lot on the density of rocks and materials nearby, and also on centrifugal force as the body rotates. So the foundational assumption of the black hole is nonsense.
