I can wrap my head around the idea of a singular event. The idea that a confluence of physics and such created a Big Bang. What was here before…there was…stuff?
If there was nothingness, then where did the raw matter come from for the Big Bang to occur? Another dimension? If there were no galaxies at all, what provided the raw material for this to occur? An empy room is still a room. An empty area in outer space is a vacuum, but it has light ( matter/energy ) and dust and whatnot. There may be a vacuum but there is stuff in there.
What could there have been that is both considered nothingness, and yet provided the raw stuff for the event?
