- Re: Notion of Absolute Clock Synchronization in SR
Gurcharn, The relative simultaneity is a consequence of : t'=\gamma(v)(t-vx/c^2) as in the Lorentz transforms The above was necessary in order to insure the frame invariance of Maxwell's em wave equation (see Lorentz' paper on the subject) By contrast, "absolute synchronization" is a consequence of: - Re: Clocks in relative motion cannot remain synchronized for any length of time.

I didn't say that. The length of the rod depends on simultaneity, and simultaneity is frame-dependent.
