Default The speed of gravity revisited

There is evidence of that when you push a car.
It pushes back instantly. But that doesn't
mean gravity moves faster than c.

The finite speed of light is in evidence
as the car begins to move forward and the
remainder of the universe shifts position just a bit
to make room for the car's field from
a new position. That realignment propagates
at less than c.


But, what must we understand
by speed of gravity?.


See above:

I can't find a source or destination in
your equations. I can with Koroupolis
and the light paths are identified.
