4. Suppose some object in space emits a muon and a photon at the same time. The muon'sdecay timescale is 2.2 usec. This is actually a characteristic decay time, but for this problem,we will assume it's the maximum lifetime of the muon. Let this object in space be at a distanceof 100 light years from Earth. How much sooner will the photon, which moves at the speed oflight, arrive at Earth than the muon?

The muon’s decay timescale corresponds to the proper time τo of the muon.In the frame of reference…
