Plus Einstien was wrong on many things . He didn’t buy Quantum Theory “God does not play dice with the universe” . And so Einstien couldn’t have been more wrong because Quantum theory is the basis for much of our electronic technology. Also Einstein was a pacifist socialist. Socialism has never worked. So I am no fan of any Socialist.
When I first read about this probe proposal — about ten years ago — there were plenty of scientists opposed to funding this remarkably expensive experiment. One summed it up nicely — said that if the probe failed to confirm frame-dragging, there wouldn’t be any way to repeat the experiment, and no one would believe it anyway, and that if it confirmed it, it would be irrelevant, because everyone already believed frame-dragging was real. :’D
The mis-assumption is that gravity travels at c. It is well known that the sun’s gravitational influence on the earth isn’t 8 minutes c-retarded, instead it’s instantaneous; wanna know why?
