Alexander KnochelThis subtlety is quickly resolved when considering a concrete example with a clearly defined question, for instance the classic question of how far atmospheric muons can travel. With a lifetime of about 2 microseconds and close to the speed of light, their majority should, naively, have decayed after a kilometre or so. Yet, they arrive at sea level without much trouble. We naturally have to judge the lifetime of muons in our rest frame by using pairs of distant clocks synchronized in our rest frame. Hence, in the game of "whose time is dilated" outlined above we are the "resting" observer whereas the muons are moving along our imagined clocks. In this perspective, the muons are subject to time dilation and can travel much further without decaying.<a href="https://scicomm.xyz/tags/physics" class="mention hashtag" rel="nofollow noopener" target="_blank">#physics</a> <a href="https://scicomm.xyz/tags/physicsedu" class="mention hashtag" rel="nofollow noopener" target="_blank">#physicsedu</a> <a href="https://scicomm.xyz/tags/scicomm" class="mention hashtag" rel="nofollow noopener" target="_blank">#scicomm</a>
