I would happily accept/consider the notion of an infinite Universe however, I hope you realize that this would totally kill off many popular views such as the Universe aging and/or expanding, etc.
Simultaneously, an infinite Universe elevates other popular ideas such as “bendable” and/or variable-length time in different locations, etc.
And, according to the theory of relativity, if time and space are indeed inseparable parameters of the universe and if the origin of the universe is the origin of space and time too, could we conclude that there was no time prior to the big bang?
Yes, but it would contradict the infinite Universe notion you started out with unless you separate between the Universe's "shell" (that which encapsulates everything) as being infinite and the contents of the universe being bound by the laws we are accustomed with.
Yet, can something else happen to time (perhaps explained by quantum mechanics) when the entire universe was concentrated in a point of infinite density (singularity = infinite density, zero volume.)? Then again, what if just time alone existed before the universe?
Well here you introduce two super-assumptions...
1. A notion that the universe was concentrated at some stage...
2. The existence of "infinite density", something unfathomably unquantifiable!
Common sense dictates that nothing can be born from nothing (of course, it was common sense for a very long time that the earth is flat). But, hold on, if empty space is nothing, how do we explain the appearance of particle-antiparticle pairs from empty space (from nothing)? Can this be the explanation of the origin of the entire universe?
I’ll wager that antiparticles would probably go far in explaining how clouds get their charge but I can’t see their relationship to the above. Also, I think we need to distinguish between "empty space" and "void"... what exactly is contained in your idea of "empty space"? All the elements necessary to produce a "big bang" by any chance?
I appreciate the serious attempt to write something interesting as opposed to all the bollocks I’ve read in the last 15 pages of the thread.
Your ideas seem to be a mix of “big bang” theory and a touch of Infinite Universe Theory but the marriage is not there.
