(do) is squishy because of near-field effects

So your electrodymanics has adaquate squishiyness to
resolve both postulates of SR.

Your "gravity" section looks vaguely like something I saw in thread
with myself (Sue) and Ken S. Tucker. The mention of the number

scalded dogs. The hasty retreat may have been just simple
deferance to the tenacity of the Brits. ;-)

Sue...
This is a colossal number!
