Is an Aether Vacuum Cleaner Possible?
Albert Einstein said that it's acceptable to say that space is endowed with physical qualities and is therefore an aether. I draw the line when aether theorists imagine that aether is a fluid that they could suck up into special containers under pressure if they only had the right materials and the right vacuum pump.
Albert Einstein agreed.

Recapitulating, we may say that according to the general theory of relativity space is endowed with physical qualities; in this sense, therefore, there exists an ether. According to the general theory of relativity space without ether is unthinkable; for in such space there not only would be no propagation of light, but also no possibility of existence for standards of space and time (measuring-rods and clocks), nor therefore any space-time intervals in the physical sense. But this ether may not be thought of as endowed with the quality characteristic of ponderable media, as consisting of parts which may be tracked through time. The idea of motion may not be applied to it. (Albert Einstein, Leiden Lecture, 1920)
