A better question would be... What is the mechanism by which a Vacuum can be warped by a mass?
What is a Vacuum composed of that gives it the property of being able to be warped by a mass?

Isn't it the curvature of space-time? Mass bends space, the heavier it is, the more it bends. Mass moves along the curves of space like a marble is attracted to a bowling ball both being situated on a tort sheet of rubber?

A vacuum is composed of dimensions, the 4th one being the one that is affected by mass to create the effect of gravity.

Anyone who can give me a satisfactory answers deserves a Nobel prize btw

A Magnetic Field does NOT have an equivilant to the graviton. It does have electrons and protons, but these create a field around them that will electrically charge anything that comes in range.

Really? I thought they were kinda just there (like fields)... I don't see how a particle can run into something and cause it to move closer.
And you're right - particle physics is confusing, and we're probably getting into stuff that's far too in advance of what either of us understands properly.

If it travels faster than light (ie, instantaneously), then that breaks some laws of physics.

If it travels faster than light (ie, instantaneously), then that breaks some laws of physics. If one had sensitive enough equipment, they could recieve a message from lightyears away instantly.
If it doesn't travel faster than light, merely at the speed of light, then that poses other problems for current theories of how galaxies and stars form.

Is this testable in the real world?
