Assuming that mass and energy are completely interchangeable inferred by mc^2, is the total energy (i.e. sum of energies of normal matter plus dark matter plus dark energy) today in our visible Universe (EVU) larger, smaller or the exact same value as the energy released at the BB (EBB)?
Case study related questions:
**1. EVU > EBB (Big RIP end?)**
a. Does this mean that energy is constantly added (i.e. Dark Energy?) in our VU and if yes what are the sources?
b. Does this infer that empty space was there before the BB which filled it with energy during inflation and that the BB does not created empty space but rather filled it with energy?
c. Does the above inequality disprove the current BB theory in some way?
d. Assuming above assumption (b) holds, can it be that the BB was a phase transition of our vacuum space (i.e. Higgs field?) which could imply that vacuum space is a kind of exotic superfluid medium (e.g. SVT theories) and an unknown matter-energy phase?
e. If (d)&(a) above assumptions hold, could this vacuum space phase transition be still ongoing today and be the main source for the dark energy and responsible for the accelerating expansion effect of our visible Universe?
h. Are there measurements or theoretical predictions?
**2. EVU < EBB (Big Crunch end?)**
a. Does this mean our VU is loosing energy? and if yes where does this energy go out?
b. Are there measurements or theoretical predictions?
**3. EVU = EBB** (has no end? Although that does not mean that it can support life forever)
a. Our VU is in a state of energy equilibrium since the BB and all its changing space-time characteristics (i.e. expansion of space) are merely due normal energy-mass transformations with the total energy however remaining at a fixed value?
b. If (a) above is correct then would that mean that our VU is an isolated closed-system?
c. Are there measurements or theoretical predictions?
