The latest hard-won confirmation of Einstein's General Theory of Relativity came recently when physicists used careful measurements of satellite orbits to show that "frame-dragging" -- a localized twisting of space-time caused by the rotation of a massive body, such as the Earth -- really does occur. More details for those so inclined (which I hope is all of you). This effect is a direct prediction of General Relativity, and was first worked out in 1918, but has never been observed before.
Enjoy this triumph while it lasts, Einstein fans. If George W. Bush is re-elected, our government's attack on science may continue to the point that our cosmology jumps backward in time from relativity to Newtonianism to a pre-Copernican worldview. Maybe even Flat-Earthism! It's GOP elephants all the way down!
