When a massive, but otherwise normal, star dies, a black hole is formed, pulling in stars and other sources of light nearby and trapping it within itself.

Black holes are really all the same. The only differences between each individual are the mass, the electric charge, and the speed of rotation.

Inside a black hole, a theory called

states that it is highly plausible that all the matter that was vacuumed into it is piled in the center.

Confusing as it may seem, it is actually a simple concept. All it really means is that when a black hole pulls things into its center, the things all meet in the

middle.

However, because it is impossible to get within a black hole, as the nearest one is light-years away and the force of gravity is so monumental that it absorbs all light, then it is unlikely that this theory will ever be

proven.

How do we know that Black Holes are There?

When black holes pass through interstellar clouds of matter, they emit x-ray radiation. Because we can see the x-rays, we know that they exist.

As a review…

Black holes have a gravitational pull so strong that not even light can escape.

There are few differences between individual black holes.

Central Singularity is the theory that states that all matter pulled inside of a black hole will come together in the center of it.

And we can tell that they exist through their x-ray emissions.
