We know that the twin paradox is not a paradox since one of the twins accelerate and time passes more slowly for him relative to his twin on earth. My question is why can't we apply the same reasoning for length contraction? If one of the twin A measures the lengths of sticks in the reference frame of B, why shouldn't B measure the length of sticks of A to be longer? My approach is natural motion is to remain unaccelerated, and acceleration causes the shortening of the sticks.(adsbygoogle = window.adsbygoogle || []).push({});
