The decay of muons is a result of the time dilation effect predicted by relativity. Muons are a type of particle that are produced in Earth's atmosphere by cosmic rays. They have a very short lifetime of about 2.2 microseconds when measured at rest. However, because they travel at near the speed of light, time appears to slow down for them relative to an observer on Earth. This means that, from our perspective, muons appear to have a longer lifetime than they actually do, allowing them to travel further and be detected on the ground. This effect has been observed in experiments and is a direct confirmation of the time dilation effect predicted by relativity.
