Default Einstein’s Asymmetric Time Dilation

ASYMMETRIC time dilation (moving clock is slow, stationary one is fast):


That was non sequitur (didn’t follow from Einstein’s 1905 postulates) but the implication was TIME TRAVEL INTO THE FUTURE - a miracle (idiocy) that converted Einstein into a deity:

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")." http://www.bourbaphy.fr/damourtemps.pdf

Einstein’s 1905 postulates entailed SYMMETRIC time dilation - either clock is slow as judged from the other clock’s system. The concept was sterile (no prediction) so Einstein fraudulently introduced non sequitur, ASYMMETRIC time dilation - moving clock is slow, stationary one is fast:

Albert Einstein, On the Electrodynamics of Moving Bodies, 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." http://www.fourmilab.ch/etexts/einstein/specrel/www/

Default Einstein’s Asymmetric Time Dilation

It follows from Einstein's 1905 postulates that time SPEEDS UP for the traveler (SYMMETRIC time dilation). As the traveler checks stationary clocks his spaceship meets against his (moving) clocks, he finds that stationary clocks are slow and his (moving) clocks are FAST, which also means that he is aging FASTER than stationary people.

Some (very few) Einsteinians obey logic and teach the correct deduction:

David Morin, Introduction to Classical Mechanics With Problems and Solutions, Chapter 11, p. 14: "Twin A stays on the earth, while twin B flies quickly to a distant star and back. [...] For the entire outward and return parts of the trip, B does observe A's clock running slow..." http://www.people.fas.harvard.edu/~djmorin/chap11.pdf

"The situation is that a man sets off in a rocket travelling at high speed away from Earth, whilst his twin brother stays on Earth. [...] ...the twin in the spaceship considers himself to be the stationary twin, and therefore as he looks back towards Earth he sees his brother ageing more slowly than himself." http://topquark.hubpages.com/hub/Twin-Paradox

High priests in Einstein cult almost universally teach that time SLOWS DOWN for the traveler (ASYMMETRIC time dilation), which is non sequitur of course:

Brian Greene: "If you're moving relative to somebody else, time for you slows down." https://m.youtube.com/watch?v=QnmnLmwBmfE

Neil deGrasse Tyson: "...Einstein's special theory of relativity, which gives the precise prescription for how time would slow down for you if you are set into motion." http://abcnews.go.com/Entertainment/...ry?id=32191481

Jim Al-Khalili: "And, the faster you move and the longer you move at that speed, the slower your clock ticks, including your own internal biological clock, and so the slower you age - by tiny, tiny fractions of a second of course." http://www.jimal-khalili.com/blogs/2...m-with-the-app
