An Attractive Proposition -

Interesting,.. very interesting that you
should raise this issue. The *effect* of
gravitation still does travel at the speed
of light, and the gravitic charge is still
instantaneous. So both GR and Newton
are in alliance on this issue, well, sort of.

You might wanta clarify a bit, Paine. What you're terming the "effect of
gravitation" would be those yet-undetected distrubances propagating at
c, ie., "gravitational waves".
GR's belief that gravity itself propagates at c is
just plain wrong, as stated previously. Whereas 'speed of charge' is
indeed instantaneous. The Fomalont-Kopeikin experiment purporting to
'prove' gravity propagates at c was in reality just a roundabout way of
measuring the speed of light.

oc My theory on gravity has always been gravitation works without
waves,and has no field.I use the graviton. I see the graviton only as a
particle(Higgs). After 62 years nothing has changed my thinking. Keep
in mind much money and lab. time has been spent to try to prove my
thinking is wrong. Trebert
