Perhaps it is too late. The metastases of the original malignancy, Einstein's false constantspeedoflight axiom, may have killed physics irreversibly. Still let us replace the fatal axiom with a correct one and see what newphysics will emerge. I have developed the idea in a series of tweets here:[..] Pentcho Valev 



"Bye bye spacetime: Is it time to free physics from Einstein's legacy?" [..]
How about LIGO's "ripples in spacetime"? Bye bye to them too? No? Spacetime goes but they remain, like the grin of the Cheshire Cat? [..] Pentcho Valev 


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 scientificformula known to just about everyone. The "c" here stands for the speed oflight. 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 thespeed of light might not be constant at all. Shock, horror! Does this meanthe next Great Revolution in Science is just around the corner?" [..]
"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 welldefined border, common to all observers, capable of containing new quantum gravitational effects." Joao Magueijo, Faster Than the Speed of Light, p. 250 [..] Nima ArkaniHamed (06:09): "Almost all of us believe that spacetime doesn'treally exist, spacetime is doomed and has to be replaced..." [..] 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." [..] "Rethinking Einstein: The end of spacetime. [...] 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." [..] New Scientist: "Saving time: Physics killed it. Do we need it back? [...] Einstein landed the fatal blow at the turn of the 20th century." [..] "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..." [..] "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 andmetaphysical dead end, says Smolin." [..] 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..." [..] "You want to go back to a notion of spacetime that preceded the 20th century, and it wants to ignore the essential lessons about spacetime that the 20th century has taught us." Joao Magueijo: "Yes, that's right. So it's nouveauNewtonian." At 53:29 here: [..] 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..." [..] "We've known for decades that spacetime is doomed," says ArkaniHamed. "Weknow it is not there in the next version 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 waysTO CHANGE THE SPEED OF LIGHT WITHOUT WRECKING THE WHOLE THING too much." [..] The speed of light is variable as per Newton (c'=c±v) so "wrecking the whole thing" is unavoidable. See more here: [..] Pentcho Valev
