TWIN PARADOX TOPPLES EINSTEIN'S RELATIVITY
http://www.people.fas.harvard.edu/~djmorin/chap11.pdf
David Morin, Introduction to Classical Mechanics With Problems and Solutions, Cambridge University Press, Chapter 11, p. 14: "Example (Twin paradox): 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." x Here is the "strangeness": http://sciliterature.50webs.com/Dialog.htm Albert Einstein: "A homogenous 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." This is perhaps the most fraudulent text in the history of science. There is no calculation showing that "this speeding ahead constitutes exactly twice as much as the lagging behind during the partial processes 2 and 4". Moreover, everybody (except for the silliest Einsteinians) knows that the acceleration ("gravitational field") is immaterial - there are twin paradox scenarios without any acceleration. No strangeness occurs during the turning-around period: For the entire outward and return parts of the trip in David Morin's scenario, B does observe A's clock running slow, and A does observe B's clock running slow. Einstein's relativity is an absurdity. Pentcho Valev |
