Default DID EINSTEIN TELL EINSTEINIANS HOW TO LEAPFROG INTO THE FUTURE?

Brian Greene: "Time Travel is Possible (2:48) If you wanted to leapfrog into the future, if you wanted to see what the Earth would be like a million years from now, Einstein told us how to do that."

https://www.youtube.com/watch?v=-O8lBIcHre0
Brian Cox (03:56): "Time travel into the future is possible".

http://www.bourbaphy.fr/damourtemps.pdf
Thibault Damour: "The paradigm of the special relativistic upheaval of the usual concept of time is the twin paradox. Let us emphasize that this striking example of time dilation proves that time travel (towards the future) is possible. As a gedanken experiment (if we neglect practicalities such as the technology needed for reaching velocities comparable to the velocity of light, the cost of the fuel and the capacity of the traveller to sustain high accelerations), it shows that a sentient being can jump, "within a minute" (of his experienced time) arbitrarily far in the future, say sixty million years ahead, and see, and be part of, what (will) happen then on Earth.. This is a clear way of realizing that the future "already exists" (as we can experience it "in a minute")."

Did Einstein tell Einsteinians how to leapfrog into the future? No he didn't. Even if his 1905 postulates were true, time travel into the future still remains an invalid conclusion. Here is the original invalidity:

http://www.fourmilab.ch/etexts/einstein/specrel/www/
ON THE ECTRODYNAMICS OF MOVING BODIES, A. Einstein, 1905: "From this there ensues the following peculiar consequence. If at the points A and B of K there are stationary clocks which, viewed in the stationary system, are synchronous; and if the clock at A is moved with the velocity v along the line AB to B, then on its arrival at B the two clocks no longer synchronize, but the clock moved from A to B lags behind the other which has remained at B by tv^2/2c^2 (up to magnitudes of fourth and higher order), t being the time occupied in the journey from A to B."

Herbert Dingle noticed the invalidity and asked a fatal question:

http://blog.hasslberger.com/Dingle_S...Crossroads.pdf
SCIENCE AT THE CROSSROADS, Herbert Dingle, p.27: "According to the special relativity theory, as expounded by Einstein in his original paper, two similar, regularly-running clocks, A and B, in uniform relative motion, must work at different rates. (...) How is the slower-working clock distinguished?"

Of course, Dingle's question is rhetorical - the slower-working clock cannot be distinguished on the basis of Einstein's 1905 postulates alone. The postulates entail that, as judged from the respective system, either clock runs slower than the other. That is, for an observer in the moving clock's system, the stationary clock at B lags behind the moving clock; for a stationary observer, the moving clock lags behind the stationary clock at B.

So Einstein's famous conclusions that made him a superstar, "moving clocks run slow" and "travel into the future is possible", are based on two flaws. Initially Einstein advanced his false constant-speed-of-light postulate, which allowed him to validly deduce that:

moving clocks run slow, as judged from the stationary system.

Then he illegitimately dropped the second part of the above conclusion and informed the gullible world that:

moving clocks run slow, that is, travel into the future is possible.

Many Einsteinians know that time travel into the future is impossibe and sometimes hint at that, preparing themselves for times when Einstein's idiocies will no longer strangle the spirit of mankind:

http://fr.wikipedia.org/wiki/Paradoxe_des_jumeaux
"Pour la plupart des commentateurs, le jumeau voyageur B a effectivement moins vieilli que son frère sédentaire A. Pour les autres, les deux jumeaux ont conservé le même âge ou le problème est sans signification. La controverse tourne autour du fait que, du point de vue de la Relativité restreinte, les situations des jumeaux ne sont pas symétriques : A coïncide avec un seul repère galiléen (en général celui de la Terre, idéalisé comme inertiel, pour l'occasion) pendant toute la durée du voyage, tandis que B effectue un demi-tour et coïncide ainsi avec au moins deux repères galiléens successifs. Cette différence fait que la relativité restreinte s'applique différemment à l'un et à l'autre, notamment à cause de l'accélération permettant le retour de B, en provoquant un changement de repère galiléen. Si, pendant la partie du voyage à vitesse constante, B vieillit moins vite que A, il se pourrait qu'il vieillisse plus vite durant les phases d'accélération. On relève 54 points de vue sur le paradoxe, émis entre 1905 (Einstein) et 2001 (Hawking).."

(1:06:45): "Est-ce que l'avenir existe déjà dans le futur ? C'est une question fondamentale ... Les relativistes disent oui - le futur est déjà là mais nous on n'y est pas encore ... Les physiciens quantiques, les présentistes disent non - le futur est un néant ... Les voyages dans le futur sont impossibles pour les présentistes alors qu'ils sont possibles pour les relativistes."

Neil deGrasse Tyson (02:22): "I have no access to the past. I have no access to the future."

"In this video lecture, Neil deGrasse Tyson, America's most noted astrophysicist, describes the Twins Paradox, a hypothetical scenario in which high-speed travel slows down the aging of one twin, while the other twin ages at a normal rate."

Slowing down the aging of the travelling twin (leapfrogging into the future) is not even a valid consequence of Einstein's 1905 postulates so it is no wonder that Einsteinians are desperately trying to get rid of Einstein's idiotic concept of time:

http://www.guardian.co.uk/books/2013...reality-review
"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.amazon.com/Time-Reborn-Cr.../dp/0547511728
"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://edge.org/response-detail/25477
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.youtube.com/watch?v=U47kyV4TMnE
Nima Arkani-Hamed (06:11): "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."

http://www.newscientist.com/article/...spacetime.html
NEW SCIENTIST: "Rethinking Einstein: The end of space-time. IT WAS a speech that changed the way we think of space and time. The year was 1908, and the German mathematician Hermann Minkowski had been trying to make sense of Albert Einstein's hot new idea - what we now know as special relativity - describing how things shrink as they move faster and time becomes distorted. "Henceforth space by itself and time by itself are doomed to fade into the mere shadows," Minkowski proclaimed, "and only a union of the two will preserve an independent reality." And so space-time - the malleable fabric whose geometry can be changed by the gravity of stars, planets and matter - was born. It is a concept that has served us well, but if physicist Petr Horava is right, it may be no more than a mirage. (...) For decades now, physicists have been stymied in their efforts to reconcile Einstein's general theory of relativity, which describes gravity, and quantum mechanics, which describes particles and forces (except gravity) on the smallest scales. 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.homevalley.co.za/index.ph...s-are-changing
"Einstein introduced a new notion of time, more radical than even he at first realized. In fact, the view of time that Einstein adopted was first articulated by his onetime math teacher in a famous lecture delivered one century ago. That lecture, by the German mathematician Hermann Minkowski, established a new arena for the presentation of physics, a new vision of the nature of reality redefining the mathematics of existence. The lecture was titled Space and Time, and it introduced to the world the marriage of the two, now known as spacetime. It was a good marriage, but lately physicists passion for spacetime has begun to diminish. And some are starting to whisper about possible grounds for divorce. (...) Einstein's famous insistence that the velocity of light is a cosmic speed limit made sense, Minkowski saw, only if space and time were intertwined. (...) Physicists of the 21st century therefore face the task of finding the true reality obscured by the spacetime mirage. (...) Andreas Albrecht, a cosmologist at the University of California, Davis, has thought deeply about choosing clocks, leading him to some troubling realizations. (...) "It seems to me like it's a time in the development of physics," says Albrecht, "where it's time to look at how we think about space and time very differently."
