I think the universe itself is a super structure that can only be observed like the proverbial orange 🍊 in 2D space where you only see a point and ever increasing cross-sections of said orange till it is a point again. Maybe the universe before the big band was that starting point of a super structure moving through 3D space and time as the 4th demention that allows it to express itself in the 3rd. So the big bang is actually just the ever increasing cross-section of this super structure.
