To bend space-time, there only needs to have the mass.


This was the great revelation in General Relativity - that the behavior of gravity could be explained not by treating it as a force that was caused by massive bodies, but rather by considering the manner in which the presence of mass caused the three-dimensional shape of spacetime to be distorted, much in the same way that the two-dimensional shape of a trampoline is distorted when you place a heavy object on it.

The resulting curve in spacetime serves to explain the nature of orbiting bodies, the bending of the path of a ray of light that passes near the mass (this was the first proof of the validity of General Relativity), as well as any other effect previously treated by Newton's law of gravitation.

I know of no other way to accomplish warping of spacetime.
