Another way to imagine wormholes is to take a sheet of paper and draw two somewhat distant points on one side of the paper. The sheet of paper represents a plane in the spacetime continuum, and the two points represent a distance to be traveled, but theoretically, a wormhole could connect these two points by folding that plane (⁠ i.e. the paper) so the points are touching. In this way, it would be much easier to traverse the distance since the two points are now touching.
