@jerry , I noticed your post on aether existence. I think modern aetherists has simply never really looked at the major challenges to the theory. And I’m not talking about Michelson & Morely. I’m talking about the elasticity and ability for aether to transmit all the light waves bouncing in so many directions without getting muddy. Many other objections were given in the 1990s – 2000s when the NPA had many questions for aetherists that to me have not been resolved.
