Yup. . . and he predicted the condition on Venus that would be found there by our Probes so accurately based on that scenario, when all other astronomers were postulating planet girdling oceans and temperatures only about 40° centigrade higher than earth on average. He also predicted the make-up of the atmosphere and pressures we found there. . . also based on his postulation on Venus being born out of Jupiter within the memory of mythological time. Velikovsky presented other arguments for his theory, then made predictions based on his theory that proved far more accurate than those of the other astronomers and cosmologists such as Sagan who called him a charlatan. . . All without reading what he had to say, or looking at his evidence, because they knew better. The test of ANY theory is how well does it predict future discoveries in the field. Velikovsky'd track record is far better than Sagan's on this.
What I remember of that Cosmos episode, “Heaven and Hell,” was that Sagan criticized the fact that other scientists tried to suppress Velikovsky’s works. If memory serves, Sagan said, “The suppression of uncomfortable ideas might be popular in religion or politics. But it is not the path to knowledge, and has no place in the endeavor of science.”
Which strikes me as a bit hypocritical coming from a guy who was on the same side as the man-made global warming folks, who are engaging in the same suppression.
