5D that's really a good q and one I've long pondered
(The casual observer should skip the film, it's very long and seems to deal with time in a very unscientific way, using another language)
Presumably "before" the Big Bang time was stopped when supposedly there was nothing at all. But this scenario has snags, almost requires a God capable of doing the impossible, with all sorts of attendant inconsistencies, contradictions, paradox entailed in Creation
The cycling scenario not needing Her and dispatching many of those difficulties starts with a ball of uniform consistency but tiny (zero?) diameter though huge (infinite?) mass, of uncertain duration (zero?) during which time is stopped but this is the only condition under which it occurs so your q may have no meaning whatever
I haven't been following the very latest, but for the sake of anyone not familiar with the Big Cycle, it's followed by Expansion (Big Bang), Organization (including evolution of the humanoid), Cooling (including expansion), then Reversal and Contraction ( the Big Crunch) until once more the tiny ball, etc etc
….the idea of infinity being dispatched by the somewhat difficult-to-picture notion of there being no "outside"
The typical religious form of Creation of course being unnecessary since She's been cycling around forever. Ergo, no inconsistency, paradoxe, contradiction
