Today we're going to discuss an interesting idea in general relativity (GR), but I'm going to try to do it without getting into any math. This will, unfortunately, limit us to a bird's eye (worm's eye?) view of it, however. In order to discuss the details of why some things are the way they are, you have to get into the nitty-gritty math of general relativity, so when I simply assert certain things to be true, you're going to have to trust me (or the physicists who said these things were true first, and proved it mathematically). So, let's talk about wormholes.
