text: Einstein comprehended that time is relative.  From the perspective of the living ... it would appear to be millions of years (or maybe not, given world events just now), but from a metaphysical point of view time is different.  It is not too difficult to understand that, relatively speaking, we could die and find ourselves at the Day of Judgement almost instantaneously.  If you're looking for an absolute truth on this question the answer is that nobody knows.
