Twin Paradox : Einstein's 1918 Preposterous Paper

[Pentcho Valev]

Grok (Elon Musk's AI): "Einstein's 1918 argument on the Twin Paradox used general relativity, suggesting the traveling twin, during acceleration, experiences a gravitational field where the stay-at-home twin's clock runs faster, making them older upon reunion. However, this idea of a "homogeneous gravitational field" is criticized as unphysical and overly complex...Einstein's 1918 approach, though historically interesting, is largely seen as flawed today."

Albert Einstein 1918: "A homogenous gravitational field appears..." http://sciliterature.50webs.com/Dialog.htm

This homogeneous gravitational field is a result of the turning-around acceleration of the traveling twin. The field extends throughout all of the Universe. In this homogeneous gravitational field creatures age very fast. The further away from the traveling twin the creature is, the faster it ages. And that's what happens to the stay-at-home twin. During the short turning-around period, the stay-at-home twin suddenly gets very old:

"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

I used to believe that this incomparable idiocy is always hidden behind euphemisms - the homogeneous gravitational field is too preposterous, even by the standards of the Einstein Cult, and Einsteinians are embarrassed to teach it directly. Then I found a video showing that some Einsteinians are not embarrassed at all:

Einstein’s 1918 use of a homogeneous gravitational field in the Twin Paradox is now considered an overcomplicated and conceptually awkward explanation. The modern interpretation via special relativity — focusing on proper time differences along distinct spacetime paths — is both simpler and more accurate.

However, Einstein's approach remains of historical interest, especially in illustrating the early development of the equivalence principle. While it may be flawed by today’s standards, dismissing it entirely without appreciating its context could be considered intellectually careless.
