We define "Present" as an instant, a very small interval of time.
We define "Past" and "Future" in relation to the Present.
Since, mathematically, to the limit, the Present is an interval of time equal to 0 (just zero), Present can't exist, nor, consequently, Past and Future...
However, we seem to agree that time came to existence at the Big-Bang and will cease to "exist" at the big-crunch (if it happens). So we must accept that time exists, and that it flows in one direction only: from past to future. However, Hawkins says that if the Universe is to go towards a big crunch, at the maximum expansion, time would reverse its flow!
Seems like a paradox. Maybe "all" "times" exist... at the same time?
Quantum leap theory is that all instants in time are present... at the same time... Human concept? Your ideas?
