Maybe Velikovski was right.
He was right in his Ages In Chaos series. While I've always been a little uneasy (I guess that's the right word) with his Worlds In Collision, that was similarly built from the ground up, and his overall view -- that the Solar System isn't just spinning down from a fixed initial condition -- has come to prevail. His more specific views have also prevailed in scrutiny. Anyone interested in witch hunts / trials of the star chamber / inquisition should at the very least come around to a study of what he had to endure.
