47 Attempts at Time Travel

"consider the analogy of a piece of paper with two pencil marks drawn on it (to represent two points in space-time), the line between them showing the distance from one point to the other in normal space-time. If the paper is now bent and folded over almost double (the equivalent of drastically warping sapce-time), then poking the pencil through the paper provides a much shorter way of linking the two points, a short-cut through space-time much like a wormhole." - NASA
