Black hole

A Black Hole Called TON 341*.

Black Holes is a possible star remnant with a singularity in its very center. As you can see on the picture, it distorts light around it by its gravity. Such distortions around normal stars are almost never seen, while a black hole literally shows you everything behind it.

Black hole is black because its escape velocity exceeds the speed of light. Not even light can escape it. Black hole is colorless, actually.

Everything CAN be a black Hole even us humans can be a black Hole given to their Schwarzschild Radius. For example our Sun cannot become a black Hole in a normal way because our Sun doesn't have enough mass to become one. But if the sun was Squeeze enough to the size of a City or roughly equal to 11 Km the sun will became a black Hole and the mass will still remain constant. But us human whatsoever we need to Squeeze ourselves to about 10^-23 meter or the Schwarzschild Radius of a Human to become a black hole.

But Small black Hole don't last long because of the hawking Radiation. Small black Hole will just Vaporize and Explode equal to 100 Megatons of TNT. So good luck creating an artificial Black holes yourself.

Structure

Photon Sphere

The Photon Sphere is the region around the Black Hole where light can actually orbit the black hole. It does not necessarily escape, and is not always sucked in into the black hole and I'm not joking here :D.

Event Horizon

The point of no return. Escape velocity exceeds the speed of light here. Theoretically, in other Universes with different laws of physics, it is possible to move faster than light. But in our Universe you can't escape your fate if you have already crossed the event horizon.

Singularity

The center of the black hole. It has zero diameter and infinite density. In the Loop Quantum Gravity theory, the singularity is instead replaced by a Planck Star, whose density corresponds to the planck density ($\thickapprox 10^{95}kg/m^{3}$).
