Einstein called it spacetime, opposite sides of the same coin. The Universe is expanding. In fact, science says the expansion is speeding up. But what is it expanding into? Time gives us a clue. What is time expanding into? Yesterday is tangible our memories intact. Tomorrow just a concept yet to be fact. The arrow of time creates history as it blithely moves along, but it moves into nothing, nothing at all. Einstein proved spacetime is a fabric with ripples and more. Space then as time is expanding into nothing, nothing at all.
