Over on Panda’s Thumb, frequent commenter Glen Davidson in a gratuitous Coulter bashing festival, asks
Where have the relativistic effects of gravity been shown in the lab?
Good lord, Glen. Relativistic effects of velocity and gravity have not only been demonstrated they are used in applied science. The Global Positioning System requires clocks so accurate and synchronized that differences in velocity and local gravity amongst orbital and ground based clocks must be compensated for in order to achieve desired accuracy. Doesn’t everyone know this? It’s really old news, Glen. Anyone claiming any broad based knowledge of science should not have asked the question you did. What’s your background again, Glen?
