Try this: what preceded the bang was a point of time, then linear expression occurred, creating first level spatial expression (linear), then the leading end of linear space burst and present time with planar space was created, which burst (the inflationary period of current fame), but only dimension space expressed in the inflation yielding volumetric space laced by present time, with the potential for future time as the solaton at the expansion edge of our spacetime universe, an edge that permeates the entire of volumetric space giving rise to the acceleration of spacetime in which matter is congealed.
Thank you for sharing your speculation on the big bang!
