David,
Thanks more! This will keep me occupied for a while!
But, right now, please clarify this ==>
In the equation (c^2)*(dτ)^2 = ((c + g*z/c)^2)*(dt)^2 -((dx)^2 + (dy)^2 + (dz)^2) ,
does the "z" in the first term of the right hand side refer to the z coordinate of the K origin as measured in K' ?
Thanks

David,
Thanks for the helpful details.
For those who are interested, here are some even more details concerning the uniformly accelerating spacecraft problem.
Suppose we have a uniformly accelerating intergalactic spaceship whose acceleration w.r.t. a sequence of instantaneously coincident inertial frames is g along the +z direction. Suppose we make our lab frame K to be at rest w.r.t. the spaceship (because the lab is on board the ship). This is a *non*inertial frame. Let's also consider a fully inertial frame K' whose velocity relative to frame K is momentarily at rest after which the K frame accelerates away from the the inertial Minkowski K' frame along the + z' direction. In this case the invariant time-like square space-time (square proper time) interval between a pair of two infinitesimally time-like separated space-time events as seen in both the inertial Minkowski K' frame and the rocket's non-inertial frame K is given by:
