So let's deal with the topic of this thread: space and spacetime. I find the basic concept of string theory very compelling: that is, elementary particles are not points as the standard model posits. In the real world there is no such thing as a dimensionless point. It's a very good assumption because the string theory particles are way smaller than we can detect, but presuming elementary particles have extension in space is surely correct, even though strings may not be. Some of the things that string theory leads to, however, are very interesting, such as M-theory and branes. The ekpyrotic theory is one that sets forth a reason why the big bang happened: https://en.wikipedia.org/wiki/Ekpyrotic_universe although I disagree with a cyclic universe as presented. Anyway, that's not necessarily a given in the theory. The universe may still be cyclic without a contraction (in agreement with the present information that the expansion is accelerating. The energy for a bang comes from the bashing of an adjacent brain into ours, as proposed in the original theory and, if it happened once, why couldn't it happen again? And again, and again, and again? This would shoot down the idea that spacetime (and space) only extends as far as the last bang (the one nearest and dearest to our hearts) has had time to expand. And then the question arises: what would be the effects of a previous band on us?
