I mean, the research is right there if you want to confirm it yourself. Extraordinary claims require extraordinary evidence, but they have it.

There was no evidence presented, just a calculation that bridged a gap and one that I am unsure if it's even right given all the forces in the universe that can affect a planetoid. I've no idea whether or not it accounts for the volume of space junk in orbit or how that acts as a sink to slow us down. It doesn't even mention the moon or where it was. Still not buying it.

I didn't actually read it, but it's AGU which is kind of a big deal. If Earth science academics got this Earth science wrong that is itself extraordinary.

I'm reading it now. Do you understand it all? It looks like they're using spherical harmonics to approximate the contributions of each water shift to the drift of the rotational pole, which I sort of get but don't really.
