We are told that space is curved by the presence of matter; that much I can grasp, but there must exist some kind of relationship between space and matter for one to affect the other. Space is supposed to be a vacuum yet how can this be when space and matter seem inextricably connected? If there was ‘nothing’ in space then it would seem to logically follow (to me at least) that space could not be curved by matter.
Any enlightenment would be appreciated. :-)
