Koobee Wublee started to learn GR with a good faith that it must be valid all along. Then, Koobee Wublee would not have dreamt that the hypothesis is nothing but a piece of shit. <shrug> > Rasjid: "Hello Tom Roberts, I finally have completed reading general > relativity - have a complete understanding of it.

That was first mentioned by Tesla. However, what if the empty space is not empty but filled with Aether? After all, the null results of the MMX can only be explained with the very existence of the absolute frame of reference. One must respect such an experiment. <shrug>
