Here are some things that are worth remembering about black holes (should it ever seem likely that you’re going to encounter one): The first is that if, at some time in the future, a group of nice scientists in white coats suggest that you—yes, you!—have been chosen as the lucky candidate to enter a black hole and find out what’s going on at the other side, it would be a very good idea for you—yes, you!—to find something else to do, preferably far away and not involving black holes, space suits, or scientists with an sly gleam in their eyes. Perhaps you’ve already worked this out for yourself, being a clever person. After all, if sticking a head, or any other part of oneself, into a black hole is such a great idea, then scientists would be queuing up to do it, instead of tapping someone else on the shoulder and inviting them to have a go. Which brings us to the second thing worth noting about black holes: your life is likely to be very short, although spectacularly eventful, if you go messing about with one. Then again, you might be lucky enough to plummet into a supermassive black hole, where the gravitational changes are a little gentler. In that case you’ll still be torn apart.. but more slowly, so you might have time to come to terms with what it feels like before you are crushed to that point of infinite density. It all depends upon the sacrifices one is willing to make for the sake of science, really. It’s your choice. Frankly, I’d find a less risky job, if I were you, like being an accountant, or feeding angry rhinos at the zoo. Oh! And here is another interesting thing about black holes: the more you struggle to escape the force of one, the quicker you’ll reach that whole part about infinite density, and crushing and stuff, due to time and space being all muddled up. Good luck, black hole explorer!
