idk where to start The black hole is probably one of the most powerful space entities. The event horizon is a point of no return. The reason black holes are black is because since theirs no light, it's just complete darkness. It is impossible to destroy a black hole. If the Singularity (the core of the black hole) is what contains all of the mass. The disc orbiting the black hole is called the Accretion Disc. The matter traveling in the accretion disc goes VERY fast. A black hole 2x the mass of our sun would be able to live VERY VERY VERY long (a number with more than 30 zeroes). In fact, black holes are going to be the last thing that exists before evaporating due to Hawking Radiation. Thats sad :(
Thanks to MelonHead for the code and stuff.
