Ether/Talk

The funny thing about the Michaelson-Morely experiment is that Einstein was already formulating relativity before he knew anything about it.

Also, wasn't the root of the english word "ether" the Latin word "aether", which means "air" as in "the sky".

You sure aether doesn't refer specifically to the upper air, which corresponds to the fifth element that fills all of space? Its Greek equivalent does, at least.
