Re: [asa] geocentricity

Regarding geocentricity, I have thought of a possible physical proof
that disproves geocentricity. I would like your thoughts on it.

Consider the phenomenon of the aberration of starlight. One definition...

"The difference between the observed position of a star and its true
direction; this is a combined result of the observer’s motion across the
path of the incoming starlight and the finite speed of light.

There are three components of the aberration of starlight: annual
aberration (up to 20.47") caused by Earth’s revolution around the Sun,
diurnal aberration (up to 0.3") caused by Earth’s axial rotation, and
the very small secular aberration caused by the motion of the solar
system through space."

Note the three components to the aberration: annual, diurnal, and
secular. The solution is to note that these definitions all assume a
point observer on a point Earth. But on the Earth we can have numerous
observers distributed in latitude. Being at different latitudes, they
each have unique diurnal aberrations as their velocities about the
Earth's axis are latitude-dependent, being maximum at the equator and
zero at the poles.

Have two observers at different latitudes note the aberration of a star
at the same time. They will measure different aberrations due to their
different latitudes. The differences will be small, but there nontheless.

Now a geocentrist can state that a reference coordinate system can be
Sun-centered, that the Earth is fixed and all the apparent movements
observed are due to the motions of those observed bodies about a fixed
Earth.

But, considering our two observers, each measuring different aberrations
requires that the observed object undergo two motions simultaneously to
produce the two observed aberrations. This, even for a geocentrist, is
impossible.

Therefore geocentricity is false.

I modestly call this the Yates Proof. If it is not true, then I won't
call it anything. :)

I have the feeling I may be overlooking something so please tell me if I am.

Thanks,
