We all know the M M experiement put to rest the eather issue...
But when we have a recognision that the Universe is made up of so much unseen matter (dark matter) and an aparently repulsive force (dark energy) and given the flow of particles and energy does this not suggest the word may have had its uses...for to a degree an environment exists with lots of stuff flying about.. the premise of the eather concept....
AND when we look at the gravity B probe mission they look for effectively a bend in the space time grid evidencing that space is effectively being dragged by mass..in this case the Earth.. and that seems more than reasonable ..now this must mean that in effect the grid line would represent the path light would take through space... so does the gravity b probe mission really do what the MM experiement could not do... whatever one calls it...space, space time or the eather ....is responding as it was expected the MM experiement looked for...if you see what I mean
... and I suspect light path will follow the grid line demonstrating the effect sought in the MM experiemnt
