A Ha: "These conditions demand the existence of time,
you can not have anything happening without having time to do it in. The big bang was a point in time. the point is: there had to be time to have that point in. If the universe is the result of an imbalance of virtual particle/energy fluctuations, that is an acceleration, meaning time^2.. all that happened in the time preceding the big bang. (read Penrose).-- We are now moving through time, following the one way arrow, since the big bang. and : on the other subject:----the moon/earth system, the Sun are waltzing, rotating along synchronized, no fairies required, obviously.
PS: all these writers, Krauss, Penrose, Carroll imply that there was time and energy in the "void" preceding the big bang, a void,- it can be assumed to still exist outside the now bigger universe, and into which it is expanding since the beginning of the movement outward. so : at what radius in time did these pre-big bang conditions disappear? but if they did not disappear, that energy can still be a property of the void, and is making it's constant appearance into the space that opens up in the expanding universe. That the gist of what I read. or?
