The reason that the twin who travels into outerspace ages more slowly than the one who stays on earth is due to the speed they travel. Time does not flow at the same rate for people travelling at different speeds but in before the difference is big enough to notice one of them has to be going at a good proportion of the speed of light. By the way this is NOT science fiction. it is a real effect that has to be taken into account by such things as the GPS system.
