In the film "Event Horizon" the main plot has it that there is a gravity drive that folds spacetime effectively allowing more or less instant travel, is this theoretically possible given the appropriate factors?

Could this actually be invented in the future given the right technologies?

Theoretically possible but so much energy is needed to warp space sufficiently that it is more difficult to acquire enough energy. I'm not sure how much it isbut it's more than the residual energy of a galaxy for example. So no I don't think it could be invented.

Hang on ....Scottty.. err what do you think?
yes it is theoretically possible. do a search on Frank Tipler and time machine, something like that. Tipler proved it mathematically . He envisioned his time machine would produce a massive gravitational field to pull spacetime around, the requirements were:

- a huge cylinder (100 km long, 10 km radius with very densely packed matter (as much as our sun).

-Revolve the cylinder very quickly (twice a millisecond)



D
Of course the gravitational forces created when space time is warped are huge - the sun warps it about a thousanth of a degree.

Get any where near the sort of cylinder Dawkins mentions from Tipler and you'd be ripped apart by the gravitational forces.

Still maybe your atoms would make it to another galaxy :c)
it would be great if somebody presented one on Dragons Den though. They could keep going back until they won
