I am reading a collection of interviews taken with prominent physicists as in an aftermath of famous Alain Aspect experiment. Between them John Bell states that if local realism has to go, he would be inclined to ditch locality, betting that there is something wrong with relativity.
I understand that relativity is truly one of the foundations of modern physics including QFT and that Lorenz transformations are tested to a great level of accuracy.
My question is, if somebody is actively working on this, as an alternative to the relativity theory ?
P.S. I mean a real alternative, not reintroducing some kind of ether/preferred reference frame which can never be detected.
