The part of the video that shows the handle spinning in microgravity is what gave me a visceral understanding of what goes on with spinning objects. I had never heard of this before. This is super important to see in order to understand that what's being discussed here is physically possible.
This explanation debunks the shift theory in that the earth is rotating around its maximum moment of inertia. The claim is that the earth can’t “flip”.
He explains the effect and why the Earth has found its apparent maximum moment but to say "won't flip" he must assume a static mass distribution. He touches upon it with the liquid in bottles. The Earth is not like Mars or asteroids due to the large amount of water on the surface and land masses moving on a liquid core. Mars (and Venus I believe) may have a liquid iron core, too, but there's no evidence yet of plate tectonics. Thus the mass distribution of Earth has and will continue to change and the geophysics isn't understood at all near well enough to draw such a conclusion. What happens when continents move? What about as the water and sea ice change? Something is causing the tide to rise and fall, why couldn't it be related to the intermediate axis? We know the Earth cycles between warm and ice ages. What if the wobble or even flips change where the Sun hits on the Earth to the extent that ice sheets form and melt as light and dark areas change? Maybe it won't flip as dramatically as the wing nut but maybe the instability grows and diminishes periodically?
That improves my understanding a bit. He differentiates between his internal and external forces, eg the cylindrical rocket whose arms disrupted the designed rotation.
I found this description of the effect helpful: https://youtu.be/1VPfZ_XzisU?si=G7X_Kn7JAnFRYzca
