Doesn't entropy sort of suggest time isn't infinite? I mean, what's the point of time without anything happening?
For similar reasons, "eternity" has always seemed to me to be more of the absense of time than just an infinite amount of time.
So events in Heaven could take place non-sequentially...or simultaneously...
But could we travel the (non-)time stream voluntarily, even drop back into time as observers of events currently in our past?
A great deal of the joy of the hereafter, I imagine, will be getting past the generalities of gold streets and perfected body and soul, and down to the specifics of abilities, activities, what do you need a mansion for if you don't need to sleep, etc.
