Once you start pulling all of real physics into it	by Talchas	2007-10-22 16:16:03
the mechanics of an instant teleport like seem like they would get ugly. I think that relativity would probably fail, but its worse than that. Since the portals can be rotated, momentum isn't conserved (really REALLY bad). If you can have one portal be moving, then I think you lose energy conservation too unless something odd happens (I remember one book that had the portals gain and lose mass, but I don't think it did anything about momentum). Does gravity cross the portal interface? I expect you break physics either way. I don't know how theories that have wormholes (if any major ones exist that actually work) compensate for any of this though, so maybe there are solutions.
