 All the matter and energy that was ever going to exist in the universe exists now, and because of Black Holes and Dark Energy, I think that these ultimately prove to be drains on both matter AND energy. -
You are assuming that the spacetime we exist in as a virtual vacuum, with quanta popping in and out was present before the Big Bang. Vilenkin has just published a paper in which he says there must be a beginnning, for this one universe and/or multiverses. What was present before the beginning? Guth, Borde cand Vilenkin in their original paper there is no 'before' before the Big Bang. But you can't get something from nothing. Since the universe is energy of whatever forms we measure or suppose, energy is eternal.
