xxein:  I figured/found most of this out in the late 80's.  Your
version carries as much weight as mine.  We differ very little, but we
do.  Nothing worthy of discussion at this time.  This was my second
confirmation that Einstein was climbing on the wrong branch.
Sloughing the Lorentzian was the first (I did create it from scratch
just like Lorentz did.  I had a mission.).

I was able to carry out this mission to include a notion of gravity,
so I was wondering what you think of gravity since we seem to think
alike.
