Aether theory was supplanted by Relativity at the beginning of the 20th century, courtesy (trumpets..) Einstein, in large part because the results were the same and Relativity was simpler. I think simpler models are better (the Ptolemaic system was asinine).
I compare Relativity to Phlogiston. Simpler, indeed, but it seems to focus on describing observations as opposed to explaining the cause for behaviors.
I am encouraged by developments in Quantum physics which seem to suggest a return to Aether in some form.
In my OPINION, Aether makes more sense in the grand scheme of things.
