Nima Arkani-Hamed has discovered that in Einstein's schizophrenic world one can get a lot of money and become millionaire by constantly repeating the following idiotic combination of phrases:

1. Spacetime doesn't exist.

2. Spacetime is doomed.

3. Spacetime has to be replaced by more primitive building blocks.

4. Spacetime has to reemerge from more primitive building blocks.

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 by some more primitive building blocks."

Nima Arkani-Hamed: "Fundamental physics started the 20th century with the twin revolutions of relativity and quantum mechanics, and much of the second half of the century was devoted to the construction of a theoretical structure unifying these radical ideas. Yet storm clouds are gathering, which point towards a new set of revolutions on the horizon in the 21st century. Space-time is doomed - how can it emerge from more primitive building blocks? And how is our macroscopic universe compatible with violent microscopic quantum fluctuations that seem to make its existence wildly implausible? In this talk I will describe these deep mysteries and outline some of our strategies for making progress on them." https://sites.google.com/a/umich.edu/lctp/other-activities/public-lectures/-the-future-of-fundamental-physics

To unify relativity and quantum mechanics means to reconcile irreconcilable concepts - Newton's absolute time and spacetime, the idiotic consequence of Einstein's 1905 false constant-speed-of-light postulate:

"The effort to unify quantum mechanics and general relativity means reconciling totally different notions of time. In quantum mechanics, time is universal and absolute; its steady ticks dictate the evolving entanglements between particles. But in general relativity (Albert Einstein's theory of gravity), time is relative and dynamical, a dimension that's inextricably interwoven with directions X, Y and Z into a four-dimensional "space-time" fabric." https://www.quantamagazine.org/20161201-quantum-gravitys-time-problem/

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/roundtable-discussion-questions/what-are-lessons-quantum

"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-feb/10-shaping-the-future-of-physics

Only LIGO's ripples in space-time will be there, like the Cheshire cat smile? The idiocies of physics are immeasurably greater than, say, the flat-earth idiocies.

Nowadays almost all theoreticians find Einstein's absurd spacetime unacceptable but continue to worship both the underlying premise, Einstein's false constant-speed-of-light postulate, and the ripples in spacetime "discovered" by LIGO conspirators:

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

"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/splitting-time-from-space/

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/mg22029410-900-saving-time-physics-killed-it-do-we-need-it-back/

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 well-defined border, common to all observers, capable of containing new quantum gravitational effects." http://www.amazon.com/Faster-Than-Speed-Light-Speculation/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/time-reborn-farewell-reality-review

"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-Crisis-Physics-Universe-ebook/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/mg22730370-600-why-do-we-move-forwards-in-time/

Brian Greene: "Special relativity in some sense is surely wrong."

"...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 space-time as a malleable fabric whose geometry can be changed by the gravity of stars, planets and matter." https://www.newscientist.com/article/mg20026831.500-what-makes-the-universe-tick
