Space Worm

Ever since Einstein said you can't travel faster than the speed of light and then glued time and space together in a fit of drunken rage, people have been trying to prove him wrong and undo his damage. Newton was outraged when his universal time got knackered up. He'd spent over a year setting the clocks in each inertial reference frame. Over a thousand years ago this century, NASA boffins (or someone else) came up with the hyperthetical concept of worm holes in space. All seemed good and righteous. No more problems with infinite energy requirement to accelerate a finite mass to c.

"Where do this worms come from and can you use them for fishing?" people asked. Nobody answered, but maybe they were just deaf. Of course, the wormholes were shown to be far far to small to drive a space-ship though, so instead something larger was needed, like a rabbit hole or a badger hole. Still a bit on the small size but a bit of spade work and you'd be there. Unfortunately the people at NASA were too lazy to use spades and so they used dynamite. Now they've made the space worms angry and they're about invade our planet with their pan-dimensional woodland friends.
