4. Suppose some object in space emits a muon and a photon at the same time. The muon's decay 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 distance of 100 light years from Earth. How much sooner will the photon, which moves at the speed of light, arrive at Earth than the muon?
