@bobc2 Sorry for wasting your time, I'm an idiot. My calculations were pointing out that we couldn't know which one is younger. And I found the answer why. I was using speed 0 for the first reference frame. No problem, that is correct. For the second one I should use speeds v or -v. I used them...

Thanks everyone @bobc2 I am aware of space-time interval, my problem was with the relativity and equivalence of frames of reference. I presumed that both systems were INERTIAL, but as Bill K pointed out, they are not. Even if acceleration was instant, in that 1 moment the system would change...

So, if I understood it correctly, SR math is right. While they travel at CONSTANT high speeds, they will both see the other one age slower. But a real difference is when Twin A changes speed. This is then a consequence of general relativity?

Hi, my first post on the forums. I've known about twin paradox for a while, so when we learned special relativity at school in September, it wasn't anything weird. Math is elegant, unlike quantum physics. But a few weeks ago, I started wondering something. It might be just an ordinary logical...
