Did you know?

If you associate wormhole with quantum physics and sci-fi, you'll probably be surprised to learn that the word has been around since William Shakespeare's day. To Shakespeare, a "wormhole" was simply a hole made by a worm, but even the Bard subtly linked wormholes to the passage of time; for example, in the poem The Rape of Lucrece, he notes time's destructive power "to fill with worm-holes stately monuments." To modern astrophysicists, a wormhole isn't a tunnel wrought by a slimy invertebrate, but a theoretical tunnel between two black holes or other points in space-time, providing a shortcut between its end points.
