Many people still think it's a complete refutation of a preferred frame theory to mock the concept of the aether and claim it's been disproven. Perhaps you're one of them, Vic, I can't remember.
But they overlook (i.e, don't know) the fact that Einstein himself completely changed his position and later said the theory of general relativity would be "unthinkable" without an aether. Of course an aether, as conceived by Lorentz, is in no way essential to a Neo-Lorentzian theory of relativity in any event.
Here's an excerpt from wiki on the topic:
Robert B. Laughlin, Nobel Laureate in Physics, endowed chair in physics, Stanford University, had this to say about ether in contemporary theoretical physics:
"The word 'ether' has extremely negative connotations in theoretical physics because of its past association with opposition to relativity. This is unfortunate because, stripped of these connotations, it rather nicely captures the way most physicists actually think about the vacuum. . . . Relativity actually says nothing about the existence or nonexistence of matter pervading the universe...It turns out that such matter exists...The modern concept of the vacuum of space, confirmed every day by experiment, is a relativistic ether. But we do not call it this because it is taboo."
But, of course, some uninformed person shouting "Einstein proved there is no aether!" is just one of many ways in which shallow posters think they have completely refuted the viability of a preferred frame theory. Once they say that, they tell you they have "already covered" anything said in response.
Of course, they often add that anyone who disputes them is a damn fool who doesn't know anything about science, ya know?
