GrapesOfWrath:
From a certain point of view, there are absolutely no aspects of Newtonian mechanics engrained in General Relativity.

Chip:
I wrote "Einsteinian physics" which includes the earlier Special Relativity of 1905. SR is applicable to the physics involved with the expansion of the universe. SR corrects the Newtonian assumption that m was constant, whereas the mass actually increases with velocity. SR follows from Newton's 2nd law. I don't get the "certain point of view" clause. Newtonian physics also works within the zone of middle dimensions.

Since the expanding universe has no perceived center, geocentric or otherwise, and distant objects are not rising, moving across the night sky, and setting at supraluminal speeds, but would appear to if someone thinks they are really that far away and moving that fast, it follows that the geocentric view is based solely on what is perceived with human eyes, and based on non-scientific doctrine, rather than taking in what is invisible to human eyes. (Odd, since religious folks have no problem accepting or having faith in the existence of the unseen.)

Likewise, the supraluminal motion of quasar jets are an illusion perhaps caused by this expansion (the receding quasar jets as seen from earth appear correspondingly slower than expected,)

GrapesofWrath:
Newtonian mechanics can be used as an approximation to GR, if certain conditions are satisfied. However, in attacking geocentrism, some people try to use Newtonian mechanics--clearly not allowed!

Chip:
The Einstein and Infeld quote concerning the sun and the earth is concerned with the relativity of reference frames in motion. As when one is on a "still" train in the station when an adjacent train moves out. One could say your train is moving and the other train is not, or visa versa. One of my points earlier is that even though you may not be able to use this to contradict geocentricism, you cannot use it to support geocentricism either.

Once you get a second observation (from the railway platform) involved, geocentricism goes out the window. [img]/phpBB/images/smiles/icon_wink.gif[/img]
