What really exists is space-time, and slicing it up into space and time is merely a useful human convention. It is here that Einstein connected the dots to suggest that gravity is the warping of space and time. Time cannot exist without the space fabric, but the space fabric can exist without time. For example, you can see that when an object orbits around another due to gravity (a motion in 4D), spacetime is like bending of a 2D rubber sheet by a heavy object placed in the middle. On the other hand, this means that general relativity is a generalized theory of nonlinear electromagnetism. The oscillations are what produces the wave.
