I remember Kant's discussions of categories... ;) It is obvious that we
must never forget that our ideal models are *not* the finite objects of
perception, but, on the other hand, if we were to be Platonists for a
while and forget about the implicit unknowability of infinite absolute
Forms, the ideal case is seen to be the bound of the limit of finite

We see that each observer has its own unique hypersurface of events
that it perceives as a *now* or "present". We must not forget that it is
only in the very special case of synchronous co-moving observers can
agree on what events make up this Now! :)
It is possible, then, to make sense of gravity in these terms: the
inability to smoothly shift from one perspective to another without
changing local gauges of clocks, rods and orderings parametrizes (?) the
curvature of the space-times involves.
I am conjecturing that there is no absolute space-time for all
observers; there is only superposition/overlap of individual
space-times, one per observer...

We denote this commensurability with inner products and orthogonality.
The algebraic properties of associativity and commutativity are brought
to the forefront...

Perhaps this number is Phi, the golden mean? ;)

I would say that time is a flowing bisimulation, computed by the
interactions of the LSs, much like a cross between a surprise 20
questions game and a soap opera. Suffice it to say that the objects of
perception are not "out there" waiting to be experienced, like some
people assume. The continuing acts of observation act contructively via
cooperation and competition to render the local reality we can the
