gravitation would exceed the centrifugal force until a distance from the surface was reached of more than double the earth's radius. Dr. Ball upon this writes that I "concluded" that when the moon was detached from the earth, "the earth's radius must have been about three times its prese...

The impact C. aused the cores of the two planets to melt together and chunks of Earth's crust to be thrown out into space. These chunks came together to form. the moon. Now, member, Earth's crust is low in iron, because the iron is in Earth's core, but high in various other ...
A number of important questions relating to the evolution of the early Earth and Moon may be investigated by using extinct as well as long-lived radionuclide chronometers. In particular, the time scale and functional shape of accretion and core formation may be investigated. The existence of earl...
