Gravity Balls

By using "the most perfect spheres ever engineered," NASA's Gravity B probe has proven subtle but very important effects predicted by Einstein's general theory of relativity. I can remember when people dismissed the theory out-of-hand because of the absurd things it implied. For me, it was when I learned that GPS wouldn't work at all if it didn't use calculations which factored in relativity that I fully embraced the thing in all its weird glory. This is just icing on the cake. Or, you know, balls.
