Re: Michelson-Morely ?
The phrase "Michelson-Morely" is used in the paper. Repeatedly I believe. In the same context you're referring to.
The detectors wouldn't work if the 'aether' was noisily drifting past. They'd never get 'lock' under such conditions.
.: They've conclusively proven there's no aether, as if it was still an open question.
DL the paper. It's lovely.
