The sun has nuclear fusion inside of it. It grows and shrinks over time. It eventually will expand greatly as it uses up most of its core hydrogen, and starts fusing heavier elements.

This would had 1 billion - 1.5 billion years to the age of the Earth. Since we know with fairly scientific certainty the age of the Earth and the length of time it takes for the processes to take place, there isn't enough time in the time frame for this theory to do what he claims it does. Considering Neal's main goal of creating this theory was to debunk what we currently believe about tectonics and about Pangaea, this little detail collides with this theory.

Actually, if we assume the earths matter is "expanding", it would have had much higher gravity on the surface than it does now. F = GMm/Rē
