The speed of gravity is a lot more
controversial, and I'm not sure it can be
measured. There seem to be a lot of
people objecting to Ed Fomalont and
Sergei Kopeikin's measurement.

Actually the Fomalont-Kopeikin experiment only measured the speed of
light in a roundabout way. It's based on the assumption that gravity
*has to* propagate away from its source, and therefore *must* propagate
at some measurable velocity. Their experiment also shows the lack of
clarification between gravity and 'gravity waves'. Even the objectors
do not seem to understand this distinction, since everybody's rooted in
the void-space paradigm.

I know Tom van Flandern has some
"interesting" views on this.

Van Flandern comes right to the point and as much as admits the
mechanism of gravity can only be explained by an underlying, flowing
medium.
