Be sure to watch closely the video. Dr. Lincoln points out that acceleration has nothing to do with the difference. This is why he replaces the original twin-paradox with a thought experiment with a new traveler, “C”.
Fair enough. After all, there’s not supposed to be any math.
I did have to go to Wikipedia to try and understand why the question was so difficult, and in the process, learned that there’s still quite a bit of active debate on the role acceleration plays in causing the disparate aging.
