Just out of curiousity, what's wrong with the theory that the aether is attached to the earth? It's no more fantastic than the hypothesis that the earth is the only inhabited piece of matter in the known universe. And if it makes it easier to "think" and explains the Michelson Morley and similar experiments and celestial obsevations, why not? Halliday and Resnick second edition comment that physicists don't like it. That's the reason? While I'm on the subject, why is it that classical physicists carefully define time and distance while special relativity simply starts with speed without first defining time?
