Einstein's 1954 Death Prognosis
Einstein made a prognosis in 1954: Physics was going to die if, and Einstein considered it "entirely possible", "field concept" and "continuous structures" turned out to be the wrong basis of physics:
Albert Einstein (1954): "I consider it entirely possible that physics cannot be based upon the field concept, that is on continuous structures. Then nothing will remain of my whole castle in the air, including the theory of gravitation, but also nothing of the rest of contemporary physics."
Sixty years later one can ask: Is physics dead? The answer seems to be "yes", although euphemisms like "crisis within the deepest foundations of physics" are often used:
Steve Giddings: "What really keeps me awake at night (...) is that we face a crisis within the deepest foundations of physics. The only way out seems to involve profound revision of fundamental physical principles."
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."
Mike Alder: "This, essentially, is the Smolin position. He gives details and examples of the death of Physics, although he, being American, is optimistic that it can be reversed. I am not."
"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?"
Hilton Ratcliffe: "Physics is dying, being suffocated by meta-mathematics, and physics departments at major universities with grand histories in physical science are closing down for lack of interest. It is a crisis in my view. (...) If, as in the case of GTR and later with Big Bang Theory and Black Hole theory, the protagonists have seductive charisma (which Einstein, Gamow, and Hawking, respectively, had in abundance) then the theory, though not the least bit understood, becomes the darling of the media. GTR and Big Bang Theory are sacrosanct, and it's most certainly not because they make any sense. In fact, they have become the measure by which we sanctify nonsense."
"However, for the past century, theoretical physicists have been sending a different message. They have rejected causality in favor of chance, logic in favor of contradictions, and reality in favor of fantasy. The science of physics is now riddled with claims that are as absurd as those of any religious cult."
"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..."
Back to Einstein's 1954 death prognosis. Needless to say, "based upon the field concept, that is on continuous structures" is a euphemism. Theoretical physics, being a deductive science, is actually based on well-known assumptions, some possibly related to "field concept" and "continuous structures". So if physics is going to crumble, as Einstein suggests, one of those assumptions must be false. Which one? Is there an assumption in modern physics which, on the one hand, is closely related to "field concept" and "continuous structures", and, on the other, is so important and indispensable that its falsehood can destroy a whole branch of science? The only such assumption is Einstein's 1905 light postulate according to which the speed of light is independent of the speed of the emitter:
"The two first articles (January and March) establish clearly a discontinuous structure of matter and light. The standard look of Einstein's SR is, on the contrary, essentially based on the continuous conception of the field."
"And then, in June, Einstein completes special relativity, which adds a twist to the story: Einstein's March paper treated light as particles, but special relativity sees light as a continuous field of waves."
Joao Magueijo: "In sharp contrast, the constancy of the speed of light has remain sacred, and the term "heresy" is occasionally used in relation to "varying speed of light theories". The reason is clear: the constancy of c, unlike the constancy of G or e, is the pillar of special relativity and thus of modern physics. Varying c theories are expected to cause much more structural damage to physics formalism than other varying constant theories."
Bryan Wallace: "Einstein's special relativity theory with his second postulate that the speed of light in space is constant is the linchpin that holds the whole range of modern physics theories together. Shatter this postulate, and modern physics becomes an elaborate farce! (...) The speed of light is c+v."
Einstein's 1905 constant-speed-of-light postulate is false - the speed of light does depend on the speed of the emitter, as predicted by Newton's emisssion theory of light.
