Yes time does not exist, except in the present instant of time, which is universal.Cargo wrote:What's an ordinary clock? Springs, Weights, SunDials, Atoms?
Time is irrelevant anyway. After all, if we can assume the Now is real, then the time it is here, is the same time every where. Right Now, it may be 3PM Earth UTC, and if I was on Pluto right now, it would also be exactly 3PM Earth UTC.
And if, by whatever method, I traveled from Pluto to Earth, in 10 minutes. It would then be 3:10 on Earth, 3:10 on Pluto, and I spent 10 minutes telling you about it.
An ordinary clock is every kind of macro clock. It does not include micro clocks, eg atomic clocks (there might be others).
I hav not given much thort to astronomical clocks, ie super-macro clocks, eg sundials. Earthly length contraction (due to change in aetherwind kmps & angle) would affect the shape & hencely the spin rate of Earth on a sidereal basis, & hencely would affect timing for star obs (but orbit rate would probly not be much affected).
