There is no error here. I have said over and over, the two frames measure the same distance along the y-axis for the location of the light sphere. That common distance is d. So, again, you demonstrate you can't follow the simple argument.
I have no interest in your silly comments. Post #238, which has not been posted 4 times, has all the specific math and conclusions. Now, exactly what statement is false?
Yes there is an error. A moving frame doesn't measure the same distance along any axis of a stationary frame when moving in a closed curve. Plus you've substituted your own version of a formula for time intervals, which is different to what Einstein uses. And he obviously means a Taylor expansion to get the approximation v[sup]2[/sup]/2c[sup]2[/sup] for the difference between the two times. You mean you have no interest in actually understanding the theory or the math. You keep asking repeatedly for someone to show which statement is false, but if someone does that you ignore it and repost the same errors. So therefore, you must not be asking anyone to find errors in your posts, you're only pretending to. You have no intention of taking anything anyone else has to say on board, or of admitting any errors. You don't want to learn anything, you want to reassure yourself that you know something nobody else does, hence the need to keep repeating the mantra: "here is the specific math". What you have is crap; it doesn't work because it's got mistakes in it, mistakes you don't want to know about. So this whole thread is pointless; trying to discuss anything with you is pointless.
