m.a. and Jason go into philosophy. Firstly: eternal is not a time limit, not even with that questionable figment of "time" we use in our imaging about our universe (for visualizing a 'physical' system).
Secondly it does not seem so safe to step out from our restricted and widely accepted solipsism of the so far learned (partially un-understood?) 'physical world' figments - using those terms we deduced from within such system (oscillatory, holographic, etc.). Thirdly: with infinite (not a number) ingredients potentially participating in unlimited Big Bangs (if we suppose such at all in terms of our yesterday's physical knowledge) in unrestricted topical variations - the probability (pardon me for that word what I find immaterial) of a TOTAL match between such events is negligible (call it zero?) And to Jason's "Lastly": I salute your indecisiveness about the term 'time' and its consequences, relativity or not.
