"Look, my lad, I know a dead parrot when I see one, and I'm looking at one right now."


Einsteinians know a dead science when they see one, and they've been looking at one since January 2001:

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." https://www.amazon.ca/Faster-Than-Speed-Light-Speculation/dp/0738205257

New Scientist: "Saving time: Physics killed it. Do we need it back? [...] Einstein landed the fatal blow at the turn of the 20th century." http://www.newscientist.com/article/mg22029410.900

"[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/

"...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." http://www.newscientist.com/article/mg20026831.500-what-makes-the-universe-tick.html

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

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."


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://edge.org/response-detail/25477

"Rethinking Einstein: The end of space-time [...] The stumbling block lies with their conflicting views of space and time. As seen by quantum theory, space and time are a static backdrop against which particles move. In Einstein's theories, by contrast, not only are space and time inextricably linked, but the resulting space-time is moulded by the bodies within it. [...] Something has to give in this tussle between general relativity and quantum mechanics, and the smart money says that it's relativity that will be the loser." http://www.newscientist.com/article/mg20727721.200-rethinking-einstein-the-end-of-spacetime.html

"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

Neil Turok: "It's the ultimate catastrophe: that theoretical physics has led to this crazy situation where the physicists are utterly confused and seem not to have any predictions at all." http://www2.macleans.ca/2013/09/05/perimeter-institute-and-the-crisis-in-modern-physics/

Frank Close: "In recent years, however, many physicists have developed theories of great mathematical elegance, but which are beyond the reach of empirical falsification, even in principle. The uncomfortable question that arises is whether they can still be regarded as science. Some scientists are proposing that the definition of what is "scientific" be loosened, while others fear that to do so could open the door for pseudo-scientists or charlatans to mislead the public and claim equal space for their views." http://www.prospectmagazine.co.uk/features/what-happens-when-we-cant-test-scientific-theories

Sabine Hossenfelder: "Many of my colleagues believe this forest of theories will eventually be chopped down by data. But in the foundations of physics it has become extremely rare for any model to be ruled out. The accepted practice is instead to adjust the model so that it continues to agree with the lack of empirical support."
http://www.nature.com.proxy.readcube.com/nphys/journal/v13/n4/full/nphys4079.html

Sabine Hossenfelder (Bee): "The criticism you raise that there are lots of speculative models that have no known relevance for the description of nature has very little to do with string theory but is a general disease of the research area. Lots of theorists produce lots of models that have no chance of ever being tested or ruled out because that's how they earn a living. The smaller the probability of the model being ruled out in their lifetime, the better. It's basic economics. Survival of the 'fittest' resulting in the natural selection of invincible models that can forever be amended." http://www.math.columbia.edu/~woit/wordpress/?p=9375

Peter Woit: "As far as this stuff goes, we're now not only at John Horgan's "End of Science", but gone past it already and deep into something different." http://www.math.columbia.edu/~woit/wordpress/?p=7266

"But instead of celebrating, physicists are in mourning after a report showed a dramatic decline in the number of pupils studying physics at school. The number taking A-level physics has dropped by 38% over the past 15 years, a catastrophic meltdown that is set to continue over the next few years. The report warns that a shortage of physics teachers and a lack of interest from pupils could mean the end of physics in state schools. Thereafter, physics would be restricted to only those students who could afford to go to posh schools. Britain was the home of Isaac Newton, Michael Faraday and Paul Dirac, and Brits made world-class contributions to understanding gravity, quantum physics and electromagnetism - and yet the British physicist is now facing extinction. But so what? Physicists are not as cuddly as pandas, so who cares if we disappear?"
http://www.guardian.co.uk/science/2005/nov/22/schools.g2

"Nous nous trouvons dans une période de mutation extrêmement profonde. Nous sommes en effet à la fin de la science telle que l'Occident l'a connue », tel est constat actuel que dresse Jean-Marc Lévy-Leblond, physicien théoricien, épistémologue et directeur des collections scientifiques des Editions du Seuil." http://archipope.over-blog.com/article-12278372.html

Peter Woit: "I think the worst thing that has happened to theoretical physics over the past 25 years is this descent into ideology, something that has accelerated with the multiverse mania of the last 10-15 years." http://www.math.columbia.edu/~woit/wordpress/?p=9375

Correct, except for the number 25 - it should be replaced by 100:

"This paper investigates an alternative possibility: that the critics were right and that the success of Einstein's theory in overcoming them was due to its strengths as an ideology rather than as a science. The clock paradox illustrates how relativity theory does indeed contain inconsistencies that make it scientifically problematic. These same inconsistencies, however, make the theory ideologically powerful. [...] The gatekeepers of professional physics in the universities and research institutes are disinclined to support or employ anyone who raises problems over the elementary inconsistencies of relativity. A winnowing out process has made it very difficult for critics of Einstein to achieve or maintain professional status. Relativists are then able to use the argument of authority to discredit these critics. Were relativists to admit that Einstein may have made a series of elementary logical errors, they would be faced with the embarrassing question of why this had not been noticed earlier. Under these circumstances the marginalisation of antirelativists, unjustified on scientific grounds, is eminently justifiable on grounds of realpolitik. Supporters of relativity theory have protected both the theory and their own reputations by shutting their opponents out of professional discourse. [...] The triumph of relativity theory represents the triumph of ideology not only in the profession of physics bur also in the philosophy of science."
