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?
