I knew at the time that it wasn't a good idea, but while at my parents' house recently I decided to flick through Graham Hancock's 'Fingerprints of the Gods'. This book had really grabbed my naive young self so I thought I'd give it another look. My God, what a piece of shit! It covers all the predictable stuff from Mayan prophecies of the apocalypse to ancient Indian nuclear wars
Anyway, I thought I'd relate to you the main beef I have with it. That is, Hancock's endorsement of Charles Hapgood's crustal displacement theory. I have real trouble believing that this was ever accepted by any scientifically literate adult, but Hancock maintains that Albert Einstein provided the introduction to the book in which it was outlined. In case you're not aware, the theory suggests that centrifugal forces acting on polar ice (due to the rotation of the Earth) are transmitted to the lithosphere, causing it to slide (as a single, intact piece) over the asthenosphere. The result is that some areas of the Earth's surface find themselves displaced by as much as 40 degrees in latitude. Hancock seems a little vague on the timescale required for this event (anything from instantaneous to 2000 years), but it is, of course, accompanied by earthquakes, volcanoes, electrical storms, plagues, gnashing of teeth and any other historical utterance that he contrives to explain.
In esposing this theory, Hancock requires you to believe that the frictional forces between the rockhead and the ice (necessarily a limited geographical area) are greater than those that exist between the lithosphere and the asthenosphere OVER THE ENTIRE SURFACE OF THE EARTH! Even if this was the case, it neglects such details as subducting plates and the deep roots of mountain ranges and continental cratons. These protrude into the mantle and would (presumably) act as pretty effective brakes to crustal movement. Hot-spot volcanism tracks are also neglected.
I apologise for the overly long post, but I've ranted on this subject until the eyes of my girlfriend and parents glaze over. Therefore I thought I'd try to burn out my fury on this forum. It hasn't worked yet, so please rant back to me.
