Is it possible, even theoretically, to bend or otherwise manipulate the fabric of space-time other than by the gravity effect of a mass?

Folks have tried to come up with theories of electromagnetism and the other forces that can be "geometrized" as Einstein did with gravity. Noone succeeded though. Only gravity can be modeled as a bending of space, and in that model, mass (or energy, which is the same thing) is the source of the curvature.

It may be possible to have a wormhole without mass, I'm not sure. That's suggested by the attached reference I just googled. I'm not sure what "phantom energy" is, though. Keep in mind, though, that wormholes may only be theoretical solutions to general relativity with no mechanism available to actually contruct one. Sort of like the joke about the guy who asked the gas station guy how to get to a town, where the answer was "you can't get there from here".

Space-time is bent by energy and mass, so its feasible that with enough energy of some kind space-time would be warped.
