In the Stargate SG-1 episode Enigma, Omoc, a Tallon, tries to explain to Daniel how two points can be far until brought together. He demonstrates this using a branch in its natural state, then bending it so the two points touch. Daniel responds with, "Oh. I learned this in freshman physics. You're talking about bending space." Omoc rebuts with, "No. You wouldn't understand."
So if Omoc wasn't talking about bending space-time or just space, then what theory could he have been referring to?
