Spacetime Deniers Against LIGO Conspirators

Nowadays most theoreticians are spacetime deniers:
Nima ArkaniHamed (06:09): "Almost all of us believe that spacetime doesn't really exist, spacetime is doomed and has to be replaced by some more primitive building blocks." https://www.youtube.com/watch?v=U47kyV4TMnE
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/responsedetail/26563
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/responsedetail/25477
"Splitting Time from Space  New Quantum Theory Topples Einstein's Spacetime. Buzz about a quantum gravity theory that sends space and time back to their Newtonian roots." https://www.scientificamerican.com/article/splittingtimefromspace/
"Rethinking Einstein: The end of spacetime. It was a speech that changed the way we think of space and time. The year was 1908, and the German mathematician Hermann Minkowski had been trying to make sense of Albert Einstein's hot new idea  what we now know as special relativity  describing how things shrink as they move faster and time becomes distorted. "Henceforth space by itself and time by itself are doomed to fade into the mere shadows," Minkowski proclaimed, "and only a union of the two will preserve an independent reality." And so spacetime  the malleable fabric whose geometry can be changed by the gravity of stars, planets and matter  was born. It is a concept that has served us well, but if physicist Petr Horava is right, it may be no more than a mirage." https://www.newscientist.com/article/mg20727721200rethinkingeinsteintheendofspacetime/
This may seem dangerous for LIGO conspirators (no spacetime ergo no ripples in spacetime ergo LIGO are fraudsters) but for the moment there is no danger  LIGO conspirators are powerful godfathers whose political strength constantly increases. Here is spacetime denier Steve Giddings who, on seeing LIGO conspirators, bows and kisses hands:
"In celebration of Einstein's birthday, physicists reflect on the Germanborn scientist's work and its impact on the field and on everyday life. "We have good reason to believe general relativity is not a complete theory and, in particular, that it's going to break down in the context of describing black holes," said UCSB physics professor Steve Giddings. "That's very much an important problem in physics today. "The direct observation of gravitational waves from colliding black holes really constrains the possible departures from general relativity that we know are there and limits where modifications can be made," he continued. "But the discovery is still spectacular and its announcement was one of those moments in science that you live for." http://www.news.ucsb.edu/2016/016562/einsteinrevolution
Still the situation will change. Everybody sees that Einstein's spacetime is idiotic and fatal for 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." https://www.newscientist.com/article/mg22029410900savingtimephysicskilleditdoweneeditback/
Joao Magueijo, Faster Than the Speed of Light, p. 250: "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." http://www.amazon.com/FasterThanSpeedLightSpeculation/dp/0738205257
"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/jun/10/timerebornfarewellrealityreview
"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/TimeRebornCrisisPhysicsUniverseebook/dp/B00AEGQPFE
"[George] Ellis is up against one of the most successful theories in physics: special relativity. It revealed that there's no such thing as objective simultaneity. [...] Rescuing an objective "now" is a daunting task." https://www.newscientist.com/article/mg22730370600whydowemoveforwardsintime/
Brian Greene: "Special relativity in some sense is surely wrong." https://www.youtube.com/watch?v=1uVZEg9gxM8
"...says John Norton, a philosopher based at the University of Pittsburgh, Pennsylvania. Norton is hesitant to express it, but his instinct  and the consensus in physics  seems to be that space and time exist on their own. The trouble with this idea, though, is that it doesn't sit well with relativity, which describes spacetime as a malleable fabric whose geometry can be changed by the gravity of stars, planets and matter." https://www.newscientist.com/article/mg20026831.500whatmakestheuniversetick
Perimeter Institute: "Quantum mechanics has one thing, time, which is absolute. But general relativity tells us that space and time are both dynamical so there is a big contradiction there. So the question is, can quantum gravity be formulated in a context where quantum mechanics still has absolute time?" https://www.perimeterinstitute.ca/research/conferences/convergence/roundtablediscussionquestions/whatarelessonsquantum
