Are we arguing the same toss of the coin though? What do you reckon to the finale? The creation concept - "An infinite state of nothing progressed into a state of everything infinitely" - in relation to what came before the Big Bang, or the moment of creation (as I prefer) ?I truly wish I knew. I easily have 200 pages of notes on this subject alone. Many of the discrete models, like loop quantum gravity, assume that spacetime is not fundamental, but emerges from something else. The problem is that these discrete models tend to violate Lorentz invariance. The Fermi observations suggest spacetime is continous, as GR predicts. This is one of the reasons we have no quantum theory of gravity. Without a quantum theory of gravity, we may never know.
Can we say that what comes before the word 'progressed' is before the Big Bang or initial point of creation, and that the word 'progressed' is the Big Bang or initial point of creation and also the point of the initiation of the beginning of the phenomenon of time itself?Events have only progressed from Planck time forward. Fundamentally, GR and most of physics only concerns itself wih events and the relationship between these events. So we measure these relationships and develop theories to describe them. Like the curvature of spacetime.
GR does not describe the initial conditions as an event. Events only occur in spacetime. In fact, events and their relationships are what define spacetime.
