In 1905 Einstein wrote: "Examples of this sort, together with the

the ``light medium,'' suggest that the phenomena of electrodynamics as

of mechanics possess no properties corresponding to the idea of absolute
rest."

In "1925 - the Michelson-Gale-Pearson experiment produces a positive
result"
(motion of the earth relatively to the ``light medium,'' )

no, its positive result was the acceleration caused by the rotation of
the earth, as in the michelson-morley experiment they detected no
motion with respect to a fix

You assume that the ether is fix. The same did Maxwell. But Maxwell did it
before MMX.
You should know (after MMX and MGX) that the ether is not fix. It rotates
with the Sun but not rotate with the Earth (it was predicted by Stokes in
1845).

or any other aether...

They "detected no motion" with respect to Stokes ether.

otherwise the result would have had a predictable variation due to time of
day or
year, which was not detected.

The results of MMX and MGX prove the Stokes ether.
