Default Einsteinians Repudiate Einstein's Spacetime

Einsteinians repudiate Einstein's spacetime, declare that it doesn't exist, but worship the underlying premise, Einstein's false constant-speed-of-light postulate, and LIGO's ripples in spacetime:

Nima Arkani-Hamed (06:09): "Almost all of us believe that space-time doesn't really exist, space-time 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

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

"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/

Einstein's spacetime "is not there in the next version of physics" - only LIGO's ripples in spacetime are there, like the grin of the Cheshire cat:

"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

Spacetime is doomed, nonexistent, should be retired etc. but the undulations of spacetime are something glorious, worth living for:

"Detection of the gravitational wave signal, resulting from the merger of two black holes, was the culmination of more than four decades of effort by researchers with funding from the U.S. National Science Foundation. "This is a marvelous prize that recognizes the heroic and successful detection of the undulations of spacetime predicted over a hundred years ago by Albert Einstein," said David Gross, winner of the 2004 Nobel Prize in Physics and Vice President of APS. "By using gravitational wave detectors, LIGO has created a new window to probe the universe." https://www.aps.org/publications/aps...es/nobel17.cfm

"In celebration of Einstein's birthday, physicists reflect on the German-born 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...ein-revolution
