felt bored, made a black hole. you can use if you want, just give me credit. For those of you who don't know what a "black hole" is; A black hole is a celestial object commonly characterized by its intense gravitational pull. It is essentially an area where the gravitational pull is so intense that anything that gets close will get sucked in and unable to come out, not even light. This is actually where their name comes from. Nobody exactly knows where they come from, but people commonly believe that they come from highly unstable stars nearing the end of their lives. Their fusion reactions are unable to overcome their own gravity, and they sort of "implode" into what is known as a "singularity." The singularity, where the gravity comes from, is a point in spacetime infinitely small but equally infinitely dense, which is where its gravity comes from. Because of this singularity (which actually morphs into a "ringularity" from the black hole's spin), black holes actually have several interesting areas and effects, which I will continue to go in detail because I really like black holes and want to talk about them. 1. The Singularity Mentioned before, the singularity, which you can consider the "heart" of the black hole, is where its intense gravity comes from. 2. The Event Horizon The event horizon is the area around the singularity. This is described as the "point of no return," where the singularity's gravity becomes too strong for an object to escape. 3. The Photon Sphere Now, as mentioned before, not even light can escape a black hole. However, there is a region just above the event horizon where light doesn't necessarily get absorbed by the black hole, but it can't escape, either. It will actually kind of "orbit." If you were floating at this point, it is theorized that you can actually see infinite copies of yourself, because the light bouncing off of the part of your body behind where you look will race all the way around the black hole and reach your eyes. Kinda neat, right? 4. The Ergosphere Now, spinning black holes are so dense that they actually drag spacetime along with it. This can be theorized with a whirlpool, the whirlpool's spin drags the surrounding water with it. So, a spaceship inside the ergosphere will actually swing around the black hole on its own. Because the ergosphere is outside the event horizon, any spaceship that accidentally got too close and entered the ergosphere can, with some effort, swing away from the influence of the ergosphere, like a gravity assist! 5. The Accretion Disk Now, whatever a black hole "eats" (and yes, they do "eat," it occurs whenever matter gets absorbed by the singularity") generally stays inside the black hole. However, there is some material that survives, but can't escape the ergosphere. This material promptly gets whipped around the black hole, sometimes to near lightspeed, and forms a ring, called the accretion disk. You can't fly into it though, because it is traveling so fast it would vaporize your ship. And that should be everything you need to know. (b^_^)b
