Where did I say that I'm arguing in favour of a rotating or a non-rotating Earth, Neil?
I'm just pointing out that if the Earth is central, and does not rotate, the revolving planets must have extremely high velocities.
They must be moving at that velocity only if you posit the heavenly bodies as being a very great distance from earth. If they are nearer, that changes the distance they need to travel.
Yes! In fact, I made this observation on the Te Deum forum a few days ago, with some additional explanation:
I think they would have to concede that the bullet disintegration analogy was poor. (By the way, Belatro, in calculating air resistance it is velocity that matters, not acceleration.) I think their issue here is kind of psychological, in that if one actually quantifies the velocity at which distant bodies would have to be traveling, the number seems absurdly high.
Here, since such calculations of velocity rely on the distance of these bodies from Earth, one effective counter-play is to question whether modern science has accurately calculated those distances. And this leads to interesting territory, because, the way I understand it, such calculations are actually based on the assumption of a heliocentric solar system. Clearly they can't argue that a geocentric universe must be false due to the velocities it necessitates when the velocities they are looking at are calculated on the basis of the Earth's movement.
However, even assuming that modern calculations are totally incorrect, to me it still seems reasonable to assume the distances involved are vast, and therefore so are the velocities. So I do not think the charge that a geocentric universe requires "break neck speeds" can be totally slipped.
