Default Einstein's 1918 Idiocy

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

Feynman is discussing Einstein's 1918 idiocy. In 1918 Einstein discovered that, as the traveling clock (twin) turns around and experiences acceleration, a HOMOGENEOUS gravitational field emerges which instantly reaches the distant stay-at-home clock (twin) and makes it run very fast (makes the stay-at-home twin age very fast) 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 calls the idiocy "enough strangeness":

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

In the quotation below Einstein's 1918 idiocy is clearly exposed, even though the emergence of the homogeneous gravitational field is not mentioned (it is too idiotic, even for the standards of Einstein's schizophrenic world):

"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

Default Einstein's 1918 Idiocy

Einstein's 1918 idiocy (the "enough strangeness" below) was not a whim - its fabrication was the only way to save relativity. Without recourse to "enough strangeness", the theory is obviously absurd - either twin sees his brother age more slowly:

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
