Worlds in Collision (1950) and Earth in Upheaval (1955) set forth the evidence and arguments for Immanuel Velikovsky’s pioneering, controversial theory that Venus emerged from Jupiter as a comet and repeatedly approached Earth, causing the Bronze Age catastrophes. Kenneth J. Dillon and Stephen J. Dillon discuss these books and the Scientific Rejectionism that stigmatized Velikovsky, thwarting a full, balanced assessment of his theories ever since.

In his Worlds in Collision (1950), pioneer scientist Immanuel Velikovsky put forward a theory that Earth had inverted during the Bronze Age Catastrophes; but many scientists considered his proposed electromagnetic cause unpersuasive. In 1982 British physicist Peter Warlow, otherwise a Velikovsky supporter, presented a gravitational explanation. Here Stephen J. Dillon and Kenneth J. Dillon of Scientia Press discuss Warlow’s The Reversing Earth (1982) and its role in the debate over Velikovsky’s theories and findings.
