Who was Immanuel Velikovsky?
He was a peer of Einstein, and they played chess together often. In fact, when Einstein died, he was in the process of reading his friend Velikovsky’s book, Earth in Upheaval, as he was found sprawled over this book, laid open on his desk, when he died – or perhaps there was something particularly upsetting, in the book. einstein was aware of periodic global cataclysms, the puzzle as to why they occurred, an issue he and Velikovsky debated, apparently. Einstein espoused Hapgood’s sliding crust theory, as an explanation for wandering poles, stating this was the best explanation for what the Earth stands in evidence of.
