Time travel? Maybe

Imagine that you're a science-fiction writer on a tight schedule. You'd like to play in the vast expanses of the universe, but you have too much scientific integrity to conjure up a warp drive or a DeLorean out of thin air. You're also concerned that your audience would get bored in the thousands of years that it would take for a spaceship to realistically travel the distances between stars. What you really need is a wormhole -- a shortcut through time and space. Best of all, unlike most science-fiction tropes, wormholes might very well be real.
