Default When Einsteinians Will Know Whether Backward Time Travel Is Possible

Kip Thorne: “We simply don’t know whether backward time travel is possible. The answer, as best I can tell, is controlled by laws of quantum gravity, laws that come from combining general relativity with quantum physics. Only when we understand those laws of quantum gravity far better than we do today will we be able, theoretically, to answer the question of whether you can go backward in time. That’s probably a few decades away.” http://thepolitic.org/an-interview-w...ize-recipient/

That is, Einsteinians will know whether backward time travel is possible when they manage to reconcile Einstein’s idiotic spacetime, the consequence of his false constant-speed-of-light postulate, and Newton’s absolute time, in the way in which theoreticians in Big Brother’s world reconcile 2+2=5 and 2+2=4:

"Special relativity is based on the observation that the speed of light is always the same, independently of who measures it, or how fast the source of the light is moving with respect to the observer. Einstein demonstrated that as an immediate consequence, space and time can no longer be independent, but should rather be considered a new joint entity called "spacetime." http://community.bowdoin.edu/news/20...rs-of-gravity/

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." https://www.youtube.com/watch?v=U47kyV4TMnE

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

"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...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-C.../dp/B00AEGQPFE

"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. Was Newton right and Einstein wrong? It seems that unzipping the fabric of spacetime and harking back to 19th-century notions of time could lead to a theory of quantum gravity. [...] But now Petr Hořava, a physicist at the University of California, Berkeley, thinks he understands the problem. It's all, he says, a matter of time. More specifically, the problem is the way that time is tied up with space in Einstein's theory of gravity: general relativity. Einstein famously overturned the Newtonian notion that time is absolute - steadily ticking away in the background. Instead he argued that time is another dimension, woven together with space to form a malleable fabric that is distorted by matter. The snag is that in quantum mechanics, time retains its Newtonian aloofness, providing the stage against which matter dances but never being affected by its presence. These two conceptions of time don't gel." https://www.scientificamerican.com/a...me-from-space/

"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

Default When Einsteinians Will Know Whether Backward Time Travel Is Possible

Kip Thorne, Nobel prize winner in the post-truth world, teaches that Newton's theory predicts no deflection as starlight passes near the sun. Only Divine Albert's Divine Theory predicts deflection, and in 1919 Sir Arthur brilliantly (and honestly of course) confirmed that prediction:

Kip Thorne: "A second crucial proof of the breakdown in Newtonian gravity was the relativistic bending of light. Einstein's theory predicted that starlight passing near the limb of the sun should be deflected by 1.75 seconds of arc, whereas NEWTON'S LAW PREDICTED NO DEFLECTION. Observations during the 1919 eclipse of the sun in Brazil, carried out by Sir Arthur Eddington and his British colleagues, brilliantly confirmed Einstein's prediction to an accuracy of about 20 percent. This dealt the final death blow to Newton's law and to most other relativistic theories of gravity." http://commons.erau.edu/cgi/viewcont...ss-proceedings

Kip Thorne is able to kill human rationality in various ways:

"The blockbuster movie Interstellar should be shown in school physics lessons because of the ground-breaking way its graphics portray wormholes, according to a leading academic journal. Christopher Nolan's film, which stars Matthew McConaughey and Anne Hathaway, would be a useful teaching tool for students learning elementary relativity theory according to a paper in the American Journal of Physics, written by the experts behind the film's jaw-dropping graphics. [...] Images of wormholes – which theoretically allow very quick travel between galaxies and universes – are a good way of teaching Einstein’s general theory of relativity, if they are scientifically accurate, the paper argues. General relativity theory holds that the universe behaves differently in extreme conditions, for example when a star turns into a black hole. "Although wormholes were central to the theme of Star Trek and Stargate, none of these have depicted correctly a wormhole as it would be seen by a nearby human. Interstellar is the first to do so," it says. It did this by imagining the wormhole's "two celestial spheres" and "Einstein ring" on its outside. The article – and another academic paper on Interstellar's depiction of black holes for Classical and Quantum Gravity - was written by Prof Kip Thorne, a leading authority on wormholes who was an executive producer on the movie..." http://www.independent.co.uk/news/sc...-10338553.html

Unlike special relativity, Einstein's general relativity is not a deductive theory. It is a not-even-wrong empirical concoction - a malleable combination of ad hoc equations and fudge factors allowing Einsteinians to predict anything they want. Its creation marked the transition from deductivism to empiricism in physics. None of the predictions of an empirical theory (should) matter. Kip Thorne, "a leading authority on wormholes", is just an extremely successful profiteer in the post-truth world.
