Hi Hans
There's a significant update on the derivation
of the Lienard-Wiechert E & B fields demonstrating
that the E field points towards the extrapolated
position instead of the retarded position.

Thanks Hans. I admire Fig 2.5, it makes
good sense seeing it that way. I was
thinking of a radiating or receiving antenna
dipole while reading it, but then you used
the Sun as a radiation emitter and the location
of it's gravitational influence perfectly.
It's good to see a bigger picture.

I made a similiar argument on Apr.8 in this
thread using GR geodesics, accounting for
aberration and rotation, but didn't apply
it to electric fields.

Hi, Ken

If people would simply understand figure 2.5
then this whole recurring discussion about
the speed of gravity wouldn't be necessary. :^)
