Well, my "limb" is probably well known ...

I don't think we "know" anything, until we deal with what part the ether
plays in all this ... I see it as we are flying a plane without paying
any heed to the existence of air--I am sure it could be done--just
happen to stumble upon a set(s) of math which would allow it--it is just
a "bunch easier" knowing about the air.
