My question is if the explanation based on differential aging(different half-lifes in this case) of a muon at rest on Earth's atmosphere and a cosmic ray traveling muon different path relative to the Earth's muon(a la twin paradox explanation) is considered exactly equivalent to the usual explanation in terms of time dilation and length contraction in different frames(earth's and muon's).
