No cute animals.

ooh I never really went into cosmology much, but this gives me an excuse to read up on black holes again. I don't know much about the gory things that would happen to one's body, but I like the trippy side black holes.
Never mind the boring standard black holes though, the ones that rotate (Kerr black holes) are much cooler:
- the first 'boundary' you'd traverse is the static limit: basically a Kerr black hole functions as a huge turbowhirlpool, so when you pass this limit you cannot remain stationary and are forced to rotate with the black hole.
- then you pass the outer event horizon, because a Kerr black hole doesn't just have one basic bitch event horizon, but two. You're irresistibly pulled towards the black hole, and I guess you undergo the ususal spaghettification and become a stretched-out noodle.
- eventually you cross the inner horizon and you apparently can move around and chill as you like again or something. Except you can't leave the black hole of course. You're in a cosmic prison chilling in a region of space with a singularity.
- actually you can escape the black hole. It has a time-opposite, a white hole, and a mathematically ideal Kerr black hole (all of this is idealised, **** reality) is linked to an infinite series of parallel universe white and black holes which you can travel through. You can probably not go back to the universe you came from, though.
- If you choose not to escape the black hole the conventional way, you can go on another adventure: the Kerr singularity is not a point, but a ring, because the black hole rotates (it literally gets called a ringularity lol). And the great thing is that there is a cut in spacetime inside this singularity, and if you go through that you end up in a funky negative space. Apparently on this side, the black hole has no horizons and is repulsive, yeeting you into negative space, but you can travel along the ring at infinite speed, which means you'd travel in time. And I guess that's all you can do there. Live happily ever after going back and forth in time along a cosmic ring. Lovely.
