- Constant Earth mass, with phase changes of an originally super-dense core. This was again rejected by Carey as the main cause of Earth expansion because the theme implied too large a surface gravity throughout the Precambrian to Late Paleozoic Eras. A large Precambrian surface gravity was not evident from studies carried out during the 1970s. For a constant Earth mass, density would have also been unacceptably high during the Precambrian.

Constant Earth Mass
"The greatest discoveries of science have always been those that forced us to rethink our beliefs about the universe and our place in it."
Re: Constant Earth Mass
Yes, I would agree that a Constant Mass Earth doesn’t fit the facts. We can estimate the surface gravity on the ancient Earth from its affects on ancient life and this indicates that the mass of the Earth must have been increasing over geological time, thereby increasing gravity as the Earth increased in diameter.
The present is the key to the past.
