One of the most famous paradoxes of all of physics – who's older? Who's younger? and WHY? ***** Thanks to The Great Courses Plus (free trial here: http://ow.ly/RCty302dIHU) for supporting...
==========
The setup for the twins paradox is as follows – suppose I sit on earth while you headoff on a rocketship at a constant speed for a while, then turn around and come back.We know that moving things experience time more slowly, so I'll think that when you getback, you should be younger than me.But from your perspective, the earth (with me on it) is doing the moving, receding andthen returning, so you think that I should be younger than you.Who's right?We'll use the fact that time rotates to sort this all out.Ok, so from my perspective, every second that passes I stay in the same place, while everysecond that passes, you get farther away, and then closer.Simple enough.From my perspective, you'll take ten seconds to get back.And since you&am...
