B What if space were a medium?

  1. Apr 8, 2016 #1
    I have read some article that describe space like a superfluid, etc.., I don't know if it is mainstream, but surely everybody agrees the vacuum is not empty at all.

    I'd ask you to try to imagine that space is found to be 'the' medium that propagates EM waves: can you explain why this hasn't yet been considered possible? What prevents space from being the ideal medium for light, like air is for sound etc? It would be nice if you would not be influenced by spacetime and relativity. What are minimal requisites?

    Apart from the cons, can you tell if, in that case, light speed would be invariant, not influenced by the speed of the observer?, the equivalence principle would be safe? what problems would remain unsolved?

    Thanks

    It has been and there are two words that you could look up. Michelson and Morley.

    Which one?

    @alba your premise is wrong, as pointed out by sophiecentaur. We really cannot discuss a wrong premise. We also cannot discuss an undisclosed reference.

    If you have an actual valid reference (per PF rules), then please open a new thread to discuss that reference.
