Immanuel Velikovsky (1895-1979) was a
Russian-American psychiatrist who in the 1950's wrote Worlds In
Collision, in which he made sensational astronomical and
historical claims. He claimed that in ancient times the planet Venus
was ejected from Jupiter in the form of a comet. Venus disrupted
Mars's orbit. Both planets buzzed Earth, Venus around 1500 B.C.E. and
Mars around 700 B.C.E., causing natural disasters that were recorded
in archeological remains, Biblical stories, and other ancient legends
and myths. Eventually, Venus and Mars settled into their current
orbits. After the publication of Worlds in Collision, some scientists
criticized Velikovsky for not going through scientific channels of
review and testing and attempted to suppress his work. The publicity
attracted readers and believers and Velikovsky's reputation grew.
His contentions have since been examined and disproved. Venus was observed in its current position around 1500 B.C.E., well before its alleged pass by Earth. Jupiter and Venus have vastly different compositions, as do comets and Venus. There is no evidence that Jupiter could eject either planets or comets. The vast spaces between and relatively small sizes of planets make close passages unlikely. Geologists have not found evidence of active volcanos and flooding that would be expected if Velikovsky's claims were true. And so on. It was the attempted suppression, not the validity of his views, that made Velikovsky's reputation.
