Near a black hole roughly the size of Earth, tidal forces are magnified off the scale. Swan-diving into one, the top of your head would feel so much more gravitational pull than the tips of your toes that you would be stretched, longer and longer. "[The British astrophysicist] Sir Martin Rees coined the term 'spaghettification,' which is a perfectly good way to put it. You eventually become a stream of subatomic particles that swirl into the black hole," Liu told Life's Little Mysteries.

Because your brain would dissociate into its constituent atoms almost instantly, you'd have little opportunity to soak in the scenery at the threshold of an Earth-size black hole.


However, if you're dead-set on visiting a space-time singularity, we recommend going big; bigger black holes have less extreme surfaces. "If you had a black hole the size of our solar system, then the tidal forces at the event horizon … are not quite that strong. So you could actually maintain your structural integrity," said Charles Liu, an astrophysicist who works at the American Museum of Natural History's Hayden Planetarium..

In that case, you would get to experience the effects of the curvature of space-time, predicted by Einstein's general theory of relativity, firsthand.

"First of all, you approach the speed of light as you fall into the black hole. So the faster you move through space, the slower you move through time," he said. "Furthermore, as you fall, there are things that have been falling in front of you that have experienced an even greater 'time dilation' than you have. So if you're able to look forward toward the black hole, you see every object that has fallen into it in the past. And then if you look backwards, you'll be able to see everything that will ever fall into the black hole behind you.

"So the upshot is, you'll get to see the entire history of that spot in the universe simultaneously," he said, "from the Big Bang all the way into the distant future."

Not such a bad way to go, in the grand scheme of things.

Longer than it will take for your lungs to rupture or the saliva on your lips, in your mouth and the mucus in your upper throat to turn to steam.
