Maybe? There might be a complete collapse of society as we know it. And a future civilization will start the clock back up again. Then it is possible that 1993 could return but that's assuming they use the same numbers as we did. Just a thought.
For me, it's more of a folk philosophical statement than a statement of physical reality. ("You can't go home again.")
On the physics end, I believe that time is an illusion. That this moment of ourself can only access this moment of ourself. We perceive time linearly but it doesn't really exist any more than space exists. Facets of the same illusion. Side effects of a situation taken to extreme limits.
We are objects afloat on waves in an ocean. We appear to move ... but move only up and down over the same position.
Even that's more of a metaphor. More precise way of saying it: some physicists believe that the furthest point in the universe precipitates its start toward collapse and that we will end up where we started. A mote in which all energy and matter exist in a single point.
The expansion and the collapse of the universe (time, space, etc.) is the same thing. We're only experiencing it as an expansion because we perceive space time as moving forward (expansion).
It is always 1993. It is always the moment of the birth of time. It is always the inevitable conclusion. It is always every moment that is time and not time.
(Not an argument or disagreement. Just an inadequate word painting of a concept I'm enamored of.)
