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 Shakespeare's day - although, admittedly, he used it more literally than most modern writers. 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 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.
