A particle accelerator is a machine that propels charged particles at nearly light speed. Invented in the 1930s, it’s used to study all things particle physics, and has led to discoveries of groundbreaking new particles like the Higgs boson. But enough about groundbreaking discoveries — what if you stuck your head in one? Perhaps the better question is why would you stick your head in one? Luckily, there are answers to both. Just ask Anatoli Bugorski, theguy who actually did it.
