Default Unavoidable Absurdity in Einstein's Relativity

"Einstein's Relativistic Train in a Tunnel Paradox: Special Relativity" https://www.youtube.com/watch?v=Xrqj88zQZJg

At 9:01 in the above video Sarah sees the train falling through the hole - an event impossible in Adam's reference frame (there the hole is much shorter than the train). We have reductio ad absurdum: It follows from Einstein's postulates that an event happening in Sarah's frame is absent in Adam's. Relativity should be abandoned but... Einsteinians are trying to save it. They explain that in Adam's frame the train undergoes a breathtaking bending (disintegration), as shown at 9:53 in the video and in this pictu

However we have reductio ad absurdum again: An idiotic bending (disintegration) occurs in Adam's reference frame but doesn't in Sarah's.

Conclusion: The underlying premise, Einstein's constant-speed-of-light postulate, is false.

Default Unavoidable Absurdity in Einstein's Relativity

In 1918 Einstein informed the gullible world that, as the traveling clock (twin) turns around and experiences acceleration, a HOMOGENEOUS GRAVITATIONAL FIELD emerges. This homogeneous gravitational field somehow affects the distant stay-at-home clock and makes it run very fast (which means that the stay-at-home twin suddenly gets very old) during the turning-around period:

Albert Einstein 1918: "A homogeneous gravitational field appears, that is directed towards the positive x-axis. Clock U1 is accelerated in the direction of the positive x-axis until it has reached the velocity v, then the gravitational field disappears again. An external force, acting upon U2 in the negative direction of the x-axis prevents U2 from being set in motion by the gravitational field. [...] According to the general theory of relativity, a clock will go faster the higher the gravitational potential of the location where it is located, and during partial process 3 U2 happens to be located at a higher gravitational potential than U1. The calculation shows that this speeding ahead constitutes exactly twice as much as the lagging behind during the partial processes 2 and 4." http://sciliterature.50webs.com/Dialog.htm

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, but ENOUGH STRANGENESS occurs during the turning-around period to make A end up older." http://www.people.fas.harvard.edu/~djmorin/chap11.pdf

"At the same time, 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. [...] Ah, but in order to return to Earth, the spaceship must slow down, stop moving, turn around and go back the other way. During those periods of deceleration and deceleration, it is not an inertial frame and therefore the normal rules of special relativity don't apply. When the twin in the spaceship turns around to make his journey home, the shift in his frame of reference causes his perception of his brother's age to change rapidly: he sees his brother getting suddenly older. This means that when the twins are finally reunited, the stay-at-home twin is the older of the two." http://topquark.hubpages.com/hub/Twin-Paradox

Einstein's 1918 idiocy was a crucial fudge factor that saved his "theory". Without recourse to the miracle ("homogeneous gravitational field", "enough strangeness") emerging in the turning-around period, Einstein's relativity predicts that either twin will find his brother younger when they reunite after the trip.

Einsteinians do teach Einstein's 1918 idiocy but never mention the "homogeneous gravitational field" - it is too idiotic, even by the standards of the Einstein cult:

Richard Feynman: "So the way to state the rule is to say that the man who has felt the accelerations, who has seen things fall against the walls, and so on, is the one who would be the younger." http://www.feynmanlectures.caltech.edu/I_16.html

John Norton: "Moments after the turn-around, when the travelers clock reads just after 2 days, the traveler will judge the stay-at-home twin's clock to read just after 7 days. That is, the traveler will judge the stay-at-home twin's clock to have jumped suddenly from reading 1 day to reading 7 days. This huge jump puts the stay-at-home twin's clock so far ahead of the traveler's that it is now possible for the stay-at-home twin's clock to be ahead of the travelers when they reunite." http://www.pitt.edu/~jdnorton/teachi...yon/index.html

Physics Girl (4:30): "One last question. What's happening to the clocks during the period of acceleration? We still get time dilation, but we have to use a different set of rules from the general relativity. General relativity states that clocks runs slower in accelerated reference frames. So while your twin is turning around, her clock runs slower, and she sees the same thing. She sees your clock running faster than hers, so you're aging quicker.. It's during this period of acceleration that you become the older twin." https://www.youtube.com/watch?v=ERgwVm9qWKA
