Hi all, I'm new here, I was on another forum asking this question but there was a lack of a response, so I hope you guys can help me out! Ok, so after a few weeks of grappling with the twin paradox, I finally accept that the twin that travels on the rocket and back is the one that ages less. (however) If both twins had a stopwatch, the stay at home twin's watch would register a longer time when the twins meet again. My question is: what would the twins observe about the other twins stopwatch (imagine they have extremely good vision :P )? The travelling twin would have to, at some point, see the stay at home twin's watch go faster, other wise how would it reach a larger value than his own? Hope that makes sense, please help!!
