This forum is biased towards relativity, but occasionally they allow discussions about the ether and these are interesting.
No one has proven that the ether doesn't exist, and your professor should know that the MMx doesn't prove it doesn't exist.
It is my strong belief that the properties of the ether allow it to form geometrical patterns around matter. And these patterns determine how matter stabilizes and what forces develop. So you ideas are sound.
