James-Jeffrey Tidal Theory
Involving the approach near the Sun of another star. This set up tidal forces, and the instability of the Sun resulted in part of its mass being torn off to form the planets.
Born in Ormskirk, Lancashire, the son of William Tulloch Jeans, a parliamentary correspondent and author. Jeans was educated at Merchant Taylors' School, Northwood, Wilson's Grammar School, Camberwell and Trinity College, Cambridge. As a gifted student, Jeans was counselled to take an aggressive approach to the Cambridge Mathematical Tripos competition:
Harold Jeffreys was a British scientist who, from 1917 on, made original contributions to the tidal hypothesis of the origin of the solar system. He also developed early models of the structures of the outer planets and was the first to propose that the Earth's core is liquid.

According to the tidal theory, the Earth was formed from materials pulled out from the sun. The theory explains that while the sun existed alone at first, there came a time when another star passed very near the sun. The movement created big tides that tore away some of the gas in the sun's outer layer. Eventually, the gas massed together and formed bodies that became planets.
