hyperspace

It's science fiction, pure and simple...

Funny reasoning. It sort of makes sense, until you get to the crux of the matter: All we have to do is pinch the universe, and we're golden!

I think the issue is more than just generating energy... for example, how is one supposed to grab two points on the universe to bring them together, without simply moving matter around within the universe? We can move entire houses, but this has no effect on the "surface" of the universe, it all occurs in the realm of space. How can we reach beyond that realm, to affect the shape of the universe? I'm not sure that's possible. Not that it isn't a fun thought experiment.

If we imagine a balloon as the space-time universe, traveling thru hyperspace is possible by pinching two points on the balloon together so as to make transit between them instantaneous. The problem would be how to generate enough energy to effect such a pinching. It would take A LOT of calories!!
