[Your questions have no answer, not in that we don't know, but we CAN'T know. Space and time as we know them were created in the Big Bang, and if there was anything before then, or is something now outside of the 4, or 10, or 22 dimensions of space time, we appear to have no means of ever seeing, detecting, understanding, or even thinking about it.]

Ok, so we don't know, but, "CAN'T know"? Remember when they thought that the Earth was flat... no land beyond the Atlantic... we'd just fall right off. lol Remember seeing your first 'close up' view of a supernova explosion courtesy of the Hubble Space Telescope?Nothing wrong in thinking, imho.
