Proposed theory is Modified Velikovsky?

worlds in collision evidence Immanuel VelikovskyA proposed theory that seems to help solve the faint young sun paradox, sounds similar to Immanuel Velikovsky's ideas and theories about Worlds in Collision and that the planet Venus is a new planet.

The basic astonishing idea is similar enough that Ray Villard the discovery.com reporter mentions Immanuel Velikovsky.

This idea leaves me a little chagrined because it sounds like some of the wacky imaginary planet Nibiru predictions for the 2012 doomsday warnings. What's more, in the 1970s Sagan ridiculed Immanuel Velikovsky's ad hoc theories of a runaway Venus and other colliding planets. Velikovsky's ideas were built around comparative mythology and not dynamical modeling.

The Venus collision model is a "plausible idea" insists Minton, but "heavy toward science fiction." It would mean that Venus didn't finish forming until 2.5 billion years ago, and that would explain Venus' appearance and a geologically young looking volcanic planet, he says.

Worlds in Collision and Migration

Now, David Minton of Purdue University has come up with a novel solution that, by his own admission, straddles science fact and fiction. Minton proposes that Earth was closer to the sun when it formed and then migrated outward to its current orbit. To keep Earth tepid under a cooler sun, our planet would have needed to have been roughly 6 million miles (9.7 million kilometers) closer to the sun than it is today.

"Planets don't like to stay still, they like to move," said Minton during a presentation at the Space Telescope Science Institute in Baltimore, Md., on April 10.

This is proven by the discovery of hundreds of extrasolar planets that reinforce a radical new idea that would have never even been considered in the 1950s: Planet migration seems the rule rather than the exception among the stars.

When you combine this new theory with the other theories and investigations into a chaotic solar system and wandering stars and planets it seems that Immanuel Velikovsky may have the last laugh.

It also helps as sort of evidence for the other Electric Universe theories (Polar Configuration, Velikovsky / Ackerman scenario, God King Scenario) on the formation of our solar system - that even if they are not the same they are on the right path or orbit.

Even more problematic is that for this musical chairs game to work at all, one more terrestrial planet is needed in the inner solar system. And, it would need to be a big one at that, ranging between the mass of Mars and Venus.

The unlucky "odd planet out" would have wound up falling into the sun, being ejected from the solar system, or crashing into another terrestrial planet.
