Thankyou for your interesting and thoughtful reply. If I understand correctly, I see the error in my analogy. (1) There is no conflict with the Principle of Equivalence as the pendulum would behave exactly the same in a X gravitational field = accelerating at X. (2) Time dilation is a...
According to general relativity (GR) time runs faster in a weak gravity field relative to a stronger one, for example: clocks run faster at the top of a tall building than at ground level. According to the principle of equivalence the accelerating space elevator should be analogous to gravity -...
