A black hole is so dense and a pull of gravity that is literally impossible to leave, not even light can escape a black hole.
Albert Einstein thought that a black hole—a collapsed star so dense that even light could not escape its thrall—was too preposterous a notion to be real. Einstein was wrong. Black holes are the final evolutionary stage of enormous stars that are at least 5 times the mass our own sun. Black holes are very far beyond anything we know as humans and anything that we know about space and time.
Black holes are the final form or a extremely large stars that are at least five times the mass of our own star. Those types of stars, near the end of their life, expand into stars that we know as red giants. They later, right before they explode, collapse in a gigantic explosion that is then right after sucked in and then creates a black hole. It is the defining factor of time and gravity. Black holes have so much mass and gravity that they literally bends gravity and even time itself. Nothing can escape a black hole’s grasp, “They are objects of extreme density, with such strong gravitational attraction that even light cannot escape from their grasp if it comes near enough.”
The density of a black holes bends matter as it enters its event horizon, the outermost part of a black hole, that spaghettifiction takes place in which matter is stretched to its maximum potential and it destroys everything that enters the black hole. If humans would try to enter a black hole, we would be stretched from the point that is closest to the black hole that we would be stretched for miles until our atoms cannot retain form.
In a black hole there are millions upon millions of nuclear explosions happening but they are absorbed so quickly that we cannot see with our naked eye. Atoms are ripped apart that they explode and create atomic explosions. Black holes also can devour stars and their energy essentially killing the star. It can suck all of the nuclear mass out of a star and grow in size from all of the mass that it has gained from the star.
Finally, there are Huge black holes at the center every galaxy that allows that stars in our galaxy to orbit its gravitational pull. The reason we have no idea of what black holes are like is because “Black holes are places where ordinary gravity has become so extreme that it overwhelms all other forces in the Universe. Once inside, nothing can escape a black hole’s gravity — not even light.” There is no need to be afraid of this though because that is not a black hole in our solar system that has the potential to kill us before the sun expands and overwhelms the earth. All in all, black holes are the final form of time and space. We have no idea what goes on inside of them because of the vent horizon. That is why it is called a black hole.
