Asking what is vibrating is like asking through what does a light wave propagate, or, What is the aether? I still have a hard time wrapping my head around the fact that spacetime isn't a physical entity, per se, but a metric of curvature. It is a purely mathematical construct, like a wavefunction. I started a fairly lengthy discussion on the physics forums with that very question and it seems there still isn't a definitive answer outside of the mathematical description. Well, it actually started with me asking just what light really is, but that led to a discussion on spacetime.
