hello everyone, this is my first post on these forums. yesterday i was at the local B&N and bought stephen hawkings "a brief history of time". I've never taken a physics course, though I've wanted to in past semesters(without calculus) but it has always interested me. in the space-time chapter i read about the infamous relativity and twins paradox. what i don't understand is WHY one twin ages more than the other merely by jetting at or nearly the speed of light. I am sure there's an easy answer but being that I've never taken a course of the subject i feel lost. any help is greatly appreciated. thanks in advance
