    Graduate What time does an observer see when watching a clock on a rotating circle?

    Yes, it is clear for me now, I was naively believing that C' (which I now know from Ben as being the carousel) could be synchronized. I could have guessed that the paradox was a proof of this impossibility (which it is I believe) :). Thanks to both of you, I can now sleep well.

    You were too fast and posted while I was replying to your first post. Your lecture is very interesting and seems to respond to my question, although it will take me some time to assimilate :) Thanks again Ben.

    Thank you Ben, and nice feedback here! OK, the problem lies then in the C' synchronization. I'm reading your section 3.4.4, thanks for the link.

    Thank you Pallen for your welcome and your prompt reply! I agree that the coordinate is not straight, but it can be made 'almost' straight by increasing the circle size, and for S large enough, the transformation will necessarily lead for t=0 to something like t'=-ax along the circle for...

    Graduate What time does an observer see when watching a clock on a rotating circle?

    Hi, I'm new here. This question may already have an answer but I didn't find it. Sorry if there's already one. It's a static version of the twin paradox, without travel and without twins. We have 2 circles C and C' that are superposed. C is fixed, with time t and co-ordinate x along the circle...
