Are there any ideas floating around concerning the possibility of the flow of time within other dimensions running in the opposite direction as time in our dimension? If we could move into another dimension with time flowing the opposite of ours, go forward in that time flow, then pop back into our dimension, the reentry would be in this dimensions past. Then, we could stay in this dimension and move forward to where we originally were. Imagine it as if it were escalators that you can hop on and off of at any time. Each esculator is a different dimension. Up is forward in time. Down is back in time.
