Lie and Truth in Post-Truth Physics

Natalie Wolchover: "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/20161...-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/re...essons-quantum

"The concepts of time (spacetime) in quantum theory and GR are thus drastically different and CANNOT BOTH BE FUNDAMENTALLY TRUE." http://hindawi.com/journals/isrn/2013/509316/

So what? In post-truth science lie and truth harmoniously coexist, "with the lie always one leap ahead of the truth":

George Orwell: "Doublethink means the power of holding two contradictory beliefs in one's mind simultaneously, and accepting both of them. The Party intellectual knows in which direction his memories must be altered; he therefore knows that he is playing tricks with reality; but by the exercise of doublethink he also satisfies himself that reality is not violated. The process has to be conscious, or it would not be carried out with sufficient precision, but it also has to be unconscious, or it would bring with it a feeling of falsity and hence of guilt. Doublethink lies at the very heart of Ingsoc, since the essential act of the Party is to use conscious deception while retaining the firmness of purpose that goes with complete honesty. To tell deliberate lies while genuinely believing in them, to forget any fact that has become inconvenient, and then, when it becomes necessary again, to draw it back from oblivion for just so long as it is needed, to deny the existence of objective reality and all the while to take account of the reality which one denies - all this is indispensably necessary. Even in using the word doublethink it is necessary to exercise doublethink. For by using the word one admits that one is tampering with reality; by a fresh act of doublethink one erases this knowledge ; and so on indefinitely, with the lie always one leap ahead of the truth."

This is the "cosmic conspiracy of the highest order" discovered by Neil deGrasse Tyson. One should revere cosmic (not Einsteinian) conspiracies, shouldn't one?

Neil deGrasse Tyson, Death by Black Hole: And Other Cosmic Quandaries, pp. 123-124: "If everyone, everywhere and at all times, is to measure the same speed for the beam from your imaginary spacecraft, a number of things have to happen. First of all, as the speed of your spacecraft increases, the length of everything - you, your measuring devices, your spacecraft - shortens in the direction of motion, as seen by everyone else. Furthermore, your own time slows down exactly enough so that when you haul out your newly shortened yardstick, you are guaranteed to be duped into measuring the same old constant value for the speed of light. What we have here is a COSMIC CONSPIRACY OF THE HIGHEST ORDER." https://www.amazon.com/Death-Black-H.../dp/039335038X

Brian Greene: "If space and time did not behave this way, the speed of light would not be constant and would depend on the observer's state of motion. But it is constant; space and time do behave this way. Space and time adjust themselves in an exactly compensating manner so that observations of light's speed yield the same result, regardless of the observer's velocity." http://www.pbs.org/wgbh/nova/physics...-nutshell.html

Whatever the wording 'fundamentally true' means. The simple quantum
mechanic ignores relativistic effects and can be applied to many cases
with high degree of accuracy. The relativistic quantum mechanic includes
such effects to some degree. The GR does not include quantum effects and
describes other scenario of the nature. In some cases gravitation can be
neglected, in other cases quantum effects can be neglected. Afaik, there
is not such one theory for all yet. A theory must also be applicable or
computable. Therefore it makes sense to apply the simplest theory that
gives the wanted accuracy.
