i got the dictionary definition, "The four-dimensional continuum of one temporal and three spatial coordinates in which any event or physical object is located.", which i understand, but i was thinking about somethin i saw on Nova, i think, that explained gravitational pull through this analogy; imagine that the sun is a bowling ball on a trampoline, and the earth is a golf ball, the sun creates a depression in space-time that draws the earth toward it.
