But in modern science we differentiate between facts/hypotheses/laws/theories. What you're referring to is a hypothesis - and those should be replaced with a more concrete explanation - once we have it. I don't quite understand your point about connecting it to ether though. I can't think of any established theory in modern science that was completely replaced - but I'm not a physicist either.
