The twin paradox doesn't seem to make logical sense according to special relativity. This is because:  It is only a thought experiment, and can't actually happen       It only happens at the quantum scale       The twins aren't both experiencing relative motion       The twins aren't both in inertial reference frame

Proper Length

The theory of special relativity explains the connection between space and time to objects that move in a straight line at a constant speed. The objects move at the speed of light. When an object approaches light speed, its mass is endless and cannot move faster than light. The most crucial postulate of Einstein's special relativity is that the laws of nature do not change in each frame of reference.
