In reply to #11:
I understand what you're saying, and I don't necessarily disagree, but you're attempting to scientifically explain that which we know very little about, and you're also viewing the "realities" of time and space in ways humans are capable of. Have you opened yourself to the possibilities that human perceptions of time and space (as well as much of the rest of the universe) are, perhaps, quite limited in scope, based in no small part on the limits of the human mind? Just the other day we received new information from a space probe that challenged much of what we thought we knew about the planet Mercury, one of our closest neighbors. My point being that in the vast realm of what we do not yet know as humans, or cannot possibly comprehend, much indeed may be possible, including time travel.
