This is an exercise in Newtonian/relativistic thumbsucking and the
contrapunctal opposite of the principles of astronomy.

So,how did Newton look at the remaining observable stars -

"Cor. 2. And since these stars are liable to no sensible parallax from
the annual motion of the earth, they can have no force, because of
their immense distance, to produce any sensible effect in our system.
Not to mention that the fixed stars, every where promiscuously
dispersed in the heavens, by their contrary actions destroy their
mutual actions, by Prop. LXX, Book I."[Principia]

In spite of this,Albert decided that Newton give a center to the
observable universe -

"This view is not in harmony with the theory of Newton. The latter
theory rather requires that the universe should have a kind of centre
in which the density of the stars is a maximum, and that as we proceed
outwards from this centre the group-density of the stars should
diminish, until finally, at great distances, it is succeeded by an
infinite region of emptiness. The stellar universe ought to be a finite
island in the infinite ocean of space."

Now,any person with common sense would see the poor guy in 1920 ,in an
era before stellar islands known as galaxies were observed,has just
rejected the notion of galaxies or what amounts to the same thing; a
new axis of rotation to incorporate heliocentric motion into.

No for the last 80 years you have been following pure homocentric
garbage and even managing to turn Copernicus into a homocentrist -

http://en.wikipedia.org/wiki/Copernican_principle

You are an embarrassing bunch with your 'sunrises and sunsets' after
half a millenia since the exquisite reasoning behind Copernican
heliocentricity emerged.
