Time is an illusion, it doesn't exist. Yet, science depends on almost
exclusively time as a dimension. Like in GR spacetime, claiming time

as

the fourth dimension is beyond stupid. Science relies on the
mathematical construct of the flow of time, so theories can go beyond

a

specific observation in a given instance.

Just because we can measure it doesn't mean we understand it.
And when we measure it, and different observers disagree with
our measurement, and relativity "explains" the disagreement,
might not really bring us closer to understanding it.
I attended a lecture many years ago where it was explained that
each of the four dimensions were really identical and we were
always moving at the speed of light - along one of them.  That
one was our time dimension.  That seemed to be very satisfying
at the time.  This would mean that there is a basic symmetry
between time and space.
More recently, some cracks in that view have appeared due to
quantum mechanics.  Vaccaro has published a couple of papers
about "Quantum asymmetry between time and space," (2016)
arXiv:1502.04012.
One idea is that time reversal would be a tough problem for
causality.
