The Twin Paradox Explained The traveling twin’s motion was not uniform. Acceleration and forces were needed to go to and return from space. Traveling twin ages more! The traveler ages more and not the one who stayed home. This is NOT science fiction. Atomic clocks placed aboard aircraft sent around Earth and back have verified the time dilation.
Length Contraction Since time is affected by relative motion, length will also be different: L L v c 0 1 2 2 L o is proper length L is relative length L o L 0.9c Moving objects are foreshortened due to to relativity.
