Why Speed in Space Stops Behaving the Way You’d Expect

You feel perfectly still right now, and that's the smoothest lie in the universe. This is a countdown through the most staggering speeds in the cosmos, from the thirty kilometers a second you're moving as you sit there, to a star whipping past a black hole fast enough that its own time slows down, to the one "speed" so enormous it isn't a speed at all and is quietly erasing the sky. By the end, fast and slow won't be the only things that stop making sense. Time will too.
