My theory: universe was never created. It always existed. We are stuck on the theory of beginning middle (now) and end. I like the recycling theory, the loop. Something exists made into something else eventually gets old then is made into something else. Apply this theory to the universe and what do we get?? We get a bang but not the big bang. 4d black whole making a 3d universe also improbable in my mind. So what happenend.? To be continued.
