[QUOTE="Umbran, post: 6638562, member: 177"] If they aren't stable, then natural ones would not last long enough for us to ever observe them, except in terms of an energy burst across teh cosmos when they collapse, so that's a bit moot. Well, in that case, these aren't really wormholes in the sense most people expect. This is effectively, "travel to a different universe," not ,"travel a distance in your own universe". I then becomes impossible to have a long route through normal space, and a short one through a wormhole. But, I've heard good folks more recent than Thorne speak about such... so I think there's something missing here. And it that raises a whole lot of questions - like how a distinct and separate space just happens to have physical laws compatible enough with those in our space to support the connection? And how would this be different from a bottleneck region in our own universe? [/QUOTE]
