A new thought experiment on relativistic length contraction

Classical Physics 2021-11-02 v1

Abstract

Relativistic length contraction is revisited and a simple but new thought experiment is proposed in which an apparent asymmetric situation is developed between two different inertial frames regarding detection of light that comes from a chamber to an adjacent chamber through a movable slit. The proposed experiment does not involve gravity, rigidity or any other dynamical aspect apart from the kinematics of relative motion; neither does it involve any kind of non-uniformity in motion. The resolution of the seemingly paradoxical situation has finally been discussed.
