There are good reasons to think that Earth and Mars originally formed a single planet outside the orbit of Jupiter.  Early in Solar System history, Jupiter’s powerful gravitational field pulled this planet past the gas giant.  As the planet neared Jupiter, tidal friction heated it to the melting point, and Jupiter tore Mars away from Earth, leaving the Pacific Basin and an array of evidence on both planets.  Earth and Mars then sped off into the inner solar system.

Mars Earth NASAThere’s no shortage of candidates for the cause of the mass extinctions of prehistory. But experts have found flaws in every one.

Asteroid impact at Chicxulub, Yucatan clearly played a role in the Cretaceous-Paleogene (K-Pg) extinction that wiped out the non-flying dinosaurs 66,000,000 years ago, though scientists point to the serious disruptions that had begun hundreds of thousands of years before with the basalt flows of the Deccan Traps.1 Giant basalt lava flows that poisoned the atmosphere and oceans played a role in four or perhaps all five major extinctions. But other enormous basalt flows have not caused extinctions, nor did they cause the tsunamis associated with various extinctions.2  Researchers have suggested many other mechanisms, but there’s no consensus at all.

Lurking in the background, however, is a quite plausible cause, one that would have possessed the power to set off the volcanic activity, air pollution, mass wasting, sea level shifts, loss of oxygen in oceans, climate changes, and other phenomena associated with the extinctions.

Once a leading theory of the origin of the Earth-Moon system, the Capture Theory is simple and intuitively plausible.  The numerous instances of moons with retrograde orbits support it.  The lunar orbit’s three moments of inertia are consistent with a past very eccentric orbit, which fit a capture1.  However, the Moon would have to come from a different part of the solar system to account for its very depleted iron compared to the Earth’s iron, which means that it would approach the Earth at a high velocity that would prevent capture.  Researchers have searched in vain for a braking mechanism that would slow it down so it could be captured.  Still, the accumulated evidence and arguments make the Capture Theory a viable one.

Jupiter And Metis Myth

A new theory of the origin of the terrestrial planets—that Jupiter’s gravity pulled them inward from the outer solar system—solves longstanding scientific riddles and offers a rich agenda for further investigation.

The origin and distribution of water on the terrestrial planets make a good place to start investigating this theory. Radiation pressure and the solar wind pushed water molecules out beyond the “snow line” around 4.5 AU, so how did Earth come to have a relatively significant amount of water?

If we can interpret ancient myths correctly, they could lead us to more accurate and penetrating views of the history of the solar system.  They might teach us about the forces at work and explain anomalies bequeathed to us by a long-hidden past.  But how can we interpret these myths, the products of minds so far removed from ours?  How do we know which interpretation is correct, if any?  Are we doomed to speculate without ever achieving certainty?

Here we will interpret two Bronze Age myths to illustrate the high scientific value such myths might contain.  We will also see how easy it can be to understand a myth once the right interpretation becomes available.

In his Worlds in Collision (New York:  Macmillan, 1950), Immanuel Velikovsky argued that Venus emerged as a red-hot comet from Jupiter and passed Earth every 52 years, causing the Bronze Age catastrophes, before settling into its current orbit.  His claim set off a controversy in which his theory was rejected and stigmatized.  But over the years, new findings have changed the picture.  Here are eight new reasons to accept a Revised Venus Theory.
