"what does God consist of in terms of mass/energy or space/time."
mass, energy, space and time are an illusion.
for example, some occurrence may appear to be green, solid, warm, and exist in time, but these properties begin to vanish along with investigation
some folk that tend to identify themselves with a particular ism, or ity, may tell you that god is omnipresent, but when you point to a piece of wood and suggest that it is a manifestation of the implicate, you could be laughed at, or be labelled as a heretic
maya, or illusion, can not be transcended until it is respected
