Do you think that there is an ether? Michelson-Gale-Pearson doesn't indicate this....
Unless you are proposing a little pocket of ether that stays still around the earth so that Michelson-Gale can detect motion but follows the earth around the sun so the Michelson-Morley cannot?
No, though this was proposed, too. AFAIR, Lorentz invented his transformations due to the thought of moving bodies being somewhat compressed by the ether...
I prefer to think of ether as a kind of phlogiston...
Um, for a second time.
Look at Michelson-Gale, don't look at Michelson-Gale-Pearson. That's a different experiment.
Michelson-Gale does indicate an ether.
Michelson-Gale-Pearson was another attempt at a Michelson-Morley experiment and again returned a null result for the motion of the earth around the sun.
