A) Proven theories have no place here, since they're not used in every aspect. Scientists fill in the holes.B) Time is in no way a spacial dimension. If you accepted that it was, you, in a way, accept that we have no free will and our destinies are predetermined. C) You said the universe was four dimensional. That's a declaration of truth.D) It's not scientific since it's not observable, testable, and repeatable.E) Nope.

A. Thus, possibility, not absolution.
B. Minkowski Space is what "four-dimensional space" is, and it is the interwoven combination of space and time. I never said that time was a spatial dimension. Just that it was [i]a[/i] dimension. It's the fourth dimension, and when woven with space we get Minkowski Space, "four-dimensional space".
C. Time is the fourth dimension, and since we observe three-dimensional space and also the movement of time, we generally accept that the universe is four-dimensional (and thus sprouts relativity, as stated in B).
D. They are possible explanations based on our perceived (observed) mathematics in relation to sciences and the universe as a whole. They're "testable" by mathematics, and those tests are repeatable. Of course these tests are not physical tests, and these theses are still only theses, and will remain theses since we can never prove them absolutely because we are not infallible and therefore don't know the maths perfectly.
