- Topic: Special Relativity A muon is an unstable subatomic particle with a mean lifetime of 2.20 μs when it's sitting still. Muons are often produced when high energy photons hit regular atoms, in Earth's upper atmosphere. Data from high-speed muons demonstrate time-dilation when more muons than expected survive the trip down from the upper atmosphere to ground-based detectors. Muons have an apparent lifetime of 19.36 μs.
