Dennis,
Is this all connected? In other words, is it more appropriate to start a thread in Theory Development on alternatives to the 'mainstream' physics that underlies celestial mechanics, astrophysics, geophysics, and cosmology? Or perhaps just a more restricted view (still in Theory Development), e.g. alternatives to GR?
Being a newbie, I rely on Mentors to make a call about "Other Sciences -> Archives". Personally, I'd welcome the chance to discuss cosmology (the Big Bang and alternatives) and astrophysics. I'd be a keen follower of discussions on nuclear and particle physics, as well as SR and GR.
If we're just discussing an idea or two about the Earth and whether its radius and/or mass has changed, and still is changing, significantly, could we have some specific hypotheses to get stuck into please?
BTW, GRACE + GPS + VLBI = pretty stringent tests of any expanding Earth hypothesis, esp as it allows for estimation of the systematic biases you referred to (e.g. location of radio telescopes), and seems to be exactly what one of the people you quoted is looking for ("On the whole, the notion of an expanding Earth is not in favour, but the topic may be revived by global geodesy").
