With this book, Immanuel Velikovsky first presented the revolutionary results of his 10-year-long interdisciplinary research to the public, founded modern catastrophism —based on eyewitness reports by our ancestors— shook the doctrine of uniformity of geology as well as Darwin's theory of evolution, put our view of the history of our solar system, of the Earth and of humanity on a completely new basis —and caused an uproar that is still going on today. Worlds in Collision —written in a brilliant, easily understandable and entertaining style and full to the brim with precise information— can be considered one of the most important and most challenging books in the history of science. Not without reason was this book found open on Einstein's desk after his death. For all those who have ever wondered about the evolution of the earth, the history of mankind, traditions, religions, mythology or just the world as it is today, Worlds in Collision is an absolute must-read.
