Stretching a circle into an ellipse provides the same results as Lorentz's gamma factor formula. Gamma = Major Axis / Minor Axis Beta = Foci.

Can someone explain how this situation works in special relativity?
Q. OK, so let's say there's twin brothers, Al and Bert. Let's say Al goes off in a rocket at .9c away from Bert for two years of Bert's time. When Al comes back, he'll be younger than Bert is. I'm fine with that. But now let's say that Al stays put and Bert shoots off in the opposite direction at .9c for two years of his time. Wouldn't Bert, when he comes back from his trip, be younger than Al? But aren't the two situations exactly the same (since velocity is relative)? Obviously, they can't both be younger than the other brother.

A. ADDED: sorry, I misread your question. The answer is that whoever is travelling will get younger. So Al will be younger than Bert when he gets back, and then Bert goes away and ages less than Al and comes back. their difference in ages will depend on who has travelled further and quicker. If they travelled at the same speed and for the same distance, they'll be the same age again :) ... but are you sure that's what you mean to ask? because there is a very famnous paradox called 'the twin paradox', composed by Einstein, which is based on what you say. imagine Al goes off for his trip and comes back younger. But can't Bert claim, well velocity is relative, so shouldn't Bert also be younger? (There is no second trip involved in the twin… [cont.]
