Mike,

i agree with your point about the subjective time schemes and the confusing phenomena to explain with regard to light, as Al E. suggested.

the idea of the rock, virtually changeless while so much goes on over eons of time is also of interest. with respect to that idea i wonder about micro states as opposed to the macro states we commonly derive our sense of time from.

classically V=dx/dt, velocity= derivative of x (position)with respect to dervative of t (time).
for velocity at an instant this is the limit as time infinitesimaly approachs zero of the change of position divided by the change of time. while it is true that velocity would be undefined when t=0 it is also regarded as true that we can infinitesimaly allow t to approach zero.
with respect to the uncertainty principle there may be a problem here at least in the micro state world of QM. (delta)E times (delta)t circa equal h(bar) indicates there is uncertainty with respect to time. the point being that perhaps within the limits of uncertainty motion might exist virtualy with out time or any meaningful time. while this scenerio would be more likely to occur in the micro state it is by no means restricted from occuring in the macro state.

regards, tim
