Astronomy UFies: geocentricity vs heliocentricity	by the_diggity	2009-10-26 14:26:44
I was recently accosted by a proponent of physical geocentricity. I know that it obviously isn't true, but when I was asked to prove it... I found that my specific knowledge on the subject was lacking. I'm familiar with Kepler and Galelei and their experiments, but can any more astronomically-inclined UFies point me in the direction of anything else? (This, of course, ignores the depressing thought that there are still proponents of geocentricity...)
