For those of you who don't know, in 2007, Neal Adams proposed an idea of an expanding Earth where all the contours of the current continental land masses actually fit together. Not as a single land mass but as a smaller planet. You do this by taking away all the larval growth between the continental land masses for the last 20 million years or more. Additionally, dinosaurs can now easily exist upon a smaller planet with a smaller gravitational load upon their skeletons.
But if Earth's always been in the same orbit around the sun, where's the mechanism to fuel this growth in planetary size? However, iff this proto-Saturn idea bears real fruit, the plasma-rich environment of Earth below Mars below Venus below a proto-Saturn or brown dwarf star, is there now a valid plasma-based source to fuel such a growing Earth? Here's Neil Adams' original (and best) video presentation.
