I'm working on a calculation to prove this is pretty much impossible, we'll see how it goes
(used to be an astrophysicist
)
Also interesting:
Modern measurements have established very stringent upper bound limits for the expansion rate, which very much reduces the possibility of an expanding Earth. For example, paleomagnetic data has been used to calculate that the radius of the Earth 400 million years ago was 102 ± 2.8% of today's radius.[6] Furthermore, examinations of earth's moment of inertia suggest that no significant change of earth's radius in the last 620 million years could have taken place and therefore earth expansion is untenable.[7]
The primary objections to an expanding Earth have centered around the lack of an accepted process by which the Earth's radius could increase and on the inability to find an actual increase of earth's radius by modern measurements. This issue, along with the evidence for the process of subduction, caused the scientific community to dismiss the theory of an expanding Earth.
Edit: Oh boy, I just read how he explained the expansion: "His divergence from older versions of Expanded Earth is his proposed mechanism of expansion, in which new mass is created by some sort of
electron/positron pair production within the core of the Earth." So the earth is creating matter now. Interesting.
