I watched a video today about time dilation and Lorenz contraction. It had Albert stationary and Henry on a moving track, both holding a photon clock, and it showed how time slows down for moving objects, relative to the stationary observer. I get all that stuff.... sorta...(adsbygoogle = window.adsbygoogle || []).push({});

I was thinking, would the same effect be observed if albert were standing at the center of a rotating merry go round, and henry is standing on the edge? I can't quite wrap my head around this one, because it seems like henry would appear to be stationary as well if albert just simply stood still and spun along with the merry go round. If he did just stand still he would observe the surroundings moving past, but if he shifted his feet so that he did not spin, he would observe Henry moving by really fast.

I'm not even sure if i'm presenting my confusion adequately. There would still be movement occurring, but all the person in the middle would have to do is change his rotation.

Someone please help.
