Perhaps it is too late. The metastases of the original malignancy, Einstein's false constant-speed-of-light axiom, may have killed physics irreversibly. Still let us replace the fatal axiom with a correct one and see what new physics will emerge. I have developed the idea in a series of tweets he https://twitter.com/pentcho_valev

How about LIGO's "ripples in space-time"? Bye bye to them too? No? Space-time goes but they remain, like the grin of the Cheshire Cat?

Paul Davies: "Was Einstein wrong? The idea of a variable speed of light, championed by an angry young scientist, could one day topple Einstein's theory of relativity. Einstein's famous equation E=mc^2 is the only scientific formula known to just about everyone. The "c" here stands for the speed of light. It is one of the most fundamental of the basic constants of physics.. Or is it? In recent years a few maverick scientists have claimed that the speed of light might not be constant at all. Shock, horror! Does this mean the next Great Revolution in Science is just around the corner?" http://www.prospectmagazine.co.uk/ma...einsteinwrong/

"Lee [Smolin] and I discussed these paradoxes at great length for many months, starting in January 2001. We would meet in cafés in South Kensington or Holland Park to mull over the problem. THE ROOT OF ALL THE EVIL WAS CLEARLY SPECIAL RELATIVITY. All these paradoxes resulted from well known effects such as length contraction, time dilation, or E=mc^2, all basic predictions of special relativity. And all denied the possibility of establishing a well-defined border, common to all observers, capable of containing new quantum gravitational effects." Joao Magueijo, Faster Than the Speed of Light, p. 250 http://www.amazon.com/Faster-Than-Sp.../dp/0738205257

Nima Arkani-Hamed (06:09): "Almost all of us believe that spacetime doesn't really exist, spacetime is doomed and has to be replaced..." https://youtu.be/U47kyV4TMnE?t=369

Nobel Laureate David Gross observed, "Everyone in string theory is convinced...that spacetime is doomed. But we don't know what it's replaced by." https://www.edge.org/response-detail/26563

"Rethinking Einstein: The end of space-time. [...] Horava, who is at the University of California, Berkeley, wants to rip this fabric apart and set time and space free from one another in order to come up with a unified theory that reconciles the disparate worlds of quantum mechanics and gravity - one the most pressing challenges to modern physics." https://www.newscientist.com/article...of-space-time/

New Scientist: "Saving time: Physics killed it. Do we need it back? [...] Einstein landed the fatal blow at the turn of the 20th century." https://www.newscientist.com/article...-need-it-back/

"Was Einstein wrong? At least in his understanding of time, Smolin argues, the great theorist of relativity was dead wrong. What is worse, by firmly enshrining his error in scientific orthodoxy, Einstein trapped his successors in insoluble dilemmas..." https://www.amazon.com/Time-Reborn-C.../dp/B00AEGQPFE

"And by making the clock's tick relative - what happens simultaneously for one observer might seem sequential to another - Einstein's theory of special relativity not only destroyed any notion of absolute time but made time equivalent to a dimension in space: the future is already out there waiting for us; we just can't see it until we get there. This view is a logical and metaphysical dead end, says Smolin." http://www.guardian.co.uk/books/2013...reality-review

What scientific idea is ready for retirement? Steve Giddings: "Spacetime. Physics has always been regarded as playing out on an underlying stage of space and time. Special relativity joined these into spacetime... [...] The apparent need to retire classical spacetime as a fundamental concept is profound..." https://www.edge.org/response-detail/25477

"You want to go back to a notion of space-time that preceded the 20th century, and it wants to ignore the essential lessons about space-time that the 20th century has taught us." Joao Magueijo: "Yes, that's right. So it's nouveau-Newtonian." At 53:29 he http://pirsa.org/displayFlash.php?id=16060116

Joao Magueijo, Niayesh Afshordi, Stephon Alexander: "So we have broken fundamentally this Lorentz invariance which equates space and time [...] It's the other postulate of relativity, that of constancy of c, that has to give way..." https://youtu.be/kbHBBtsrU1g?t=1431

"We've known for decades that space-time is doomed," says Arkani-Hamed. "We know it is not there in the next version of physics." http://discovermagazine.com/2014/jan...ure-of-physics

"The whole of physics is predicated on the constancy of the speed of light," Joao Magueijo, a cosmologist at Imperial College London and pioneer of the theory of variable light speed, told Motherboard. "So we had to find ways TO CHANGE THE SPEED OF LIGHT WITHOUT WRECKING THE WHOLE THING too much." https://motherboard.vice.com/en_us/a...t-speed-slowed

The speed of light is variable as per Newton (c'=c±v) so "wrecking the whole thing" is unavoidable.
