Dominant theories have been known to stand for some time after overwhelmingly disconfirming evidence against them is discovered. Galileo is not the first scientist to have discovered this unfortunate fact, though he is often credited with the most memorably disgruntled riposte to it. After being forced to recant his theory that the earth revolved around the sun, he is alleged to have mumbled to himself ‘Eppure, si muove’ (And yet, it still moves) – the earth, that is, against the expectations of the dominant geocentric theory of Galileo’s time.
