It would seem to me that we exist in an infinitely large space. That a big bang could not encompass all matter because all space extends infinitely. That with infinite space there is infinite possibilities for things to happen, such as for matter to exist. That space can exist and is infinite, and that matter is allowed to exist within space, because 0≠0, because nothing is something. That a big bang is a measurable explosion, and one that can be considered large or small, just as we see small and large explosions on our planet. Not saying that big bangs may occur in different sizes, more like the size of the explosion is in the eye of the beholder. That the contents of a big bangs explosion cannot be the entirety of a universe, that the universe is singular and infinite, that there is no such use for multiverse theory. Would anybody like to comment anything? This is just my amateur ideas.
