A new theory of the origin of the terrestrial planets appears to solve longstanding scientific riddles.
Researchers have encountered repeated frustration in their efforts to agree on how Earth came to have a significant amount of water. Meanwhile, the giant impact theory of the origin of the Earth-Moon system requires an elaborate scenario that seems impossible to verify and is undermined by new evidence. And none of the scores of hypotheses of the cause of the mass extinctions of prehistory has gained acceptance. Yet the new theory of the origin of the terrestrial planets can solve all three problems, and minor ones as well. Continue reading »
Immanuel Velikovsky argued famously, based on his interpretation of ancient sources, that Venus had emerged from Jupiter as a comet, interacted with the Earth and Mars in the second and first millennia B.C., and then finally settled into a nearly circular orbit of the Sun.
Here are three new lines of reasoning that tend to support this theory:
1. Instead of the various unpersuasive suggestions that Velikovsky and others have made for how a cometary Venus could have emerged from Jupiter, we should consider the possible consequences of the immense gravitational field of Jupiter, which pulls into the giant planet a stream of asteroids and comets such as Shoemaker-Levy 9 in 1994.
