My Son at Uni (astrophysics), says the ether is making a comeback. Any thoughts? Turning this over in my head I wondered if the Michaelson Morley just proved what it wanted to. If gravity shapes space and space is the ether, might it stretch and shrink to make the results work. That is if the orbits are shaped by the curvature of space then the ether (space) is warped to make the results appear valid. Need a lie down now. Perhaps it was Esher football team that was on a comeback and he misheard.
