the muon’s proper length in meters, the term 𝑥2 may be neglected in the above expression, and its length in the Earth frame, 𝑥′ works out to 14747 𝑚≈14.8 𝑘𝑚. It shows that a negligible length of muon should also be seen, in the Earth’s frame, as lengthened to ≈14.8 km, along with the lengthening of
