Space creates its own time. We are aware of that now. Spacetime ticks to
its own clock,and we are smart enough to know we will never see its
hands. This begs the question "What is the most important "space" or
"time"?  I have a feeling Einstein would say "time"  I have  lots more
to add to this,and so should "you all" Bert

I really think the issue is not one of mathematical principles, like
Cartesian coordinates, but instead one of how those principles relate
to the physiology of our brain. For example, not the fact that 1+1=2
and deriving consequences from that, but instead the process of
traversing between two distinguishable regions of space mentally, as
that happens within our brain in reality, and categorizing that
traversal. Penrose gives the equation for entropy as S = k log V, where
V is the volume of a macroscopically indinguishable set of states, and
k is Boltzmann's constant. Maybe this has something *to do with* the
integers. Thinking about this more deeply, it seems that extra
variables that could relate to any type of condition in our universe
could impact the spatial and temporal dimensions that we perceive. Call
one quantity, "x", and no matter what this quantity is, it is a
dimension.

The problem with finding the master equation in this way is, how would
we be certain that we can predict any hidden variables that might be
part of an equation of the universe?

Which is most important?

That's like asking, which is more important, time or money?

It all epends on which you have the least of!
