|The nature of time is still a
mystery to physicists.
Physicists use time in many equations as a 4th dimension,
along which matter is remorselessly driven, a one way street
that we are forced along at a constant rate. The arrow of time.
Basically physicists have no further understanding than that. If
you don't believe me, go and search.
In the 1928 book The Nature of the Physical
World, , Eddington states:
“ Let us draw an arrow arbitrarily. If as we follow the arrow we
find more and more of the random element in the state of the
world, then the arrow is pointing towards the future; if the
random element decreases the arrow points towards the past. That
is the only distinction known to physics. This follows at once
if our fundamental contention is admitted that the introduction
of randomness is the only thing which cannot be undone. I shall
use the phrase ‘time’s arrow’ to express this one-way property
of time which has no analogue in space. ”
Eddington notes about this arrow, it is recognized by
consciousness and common sense dictates that without it, there
would be no sequence to events, which would be nonsensical.
