QUANTUM SNARK

Muon particles can penetrate Earth’s atmosphere due to time dilation. Relativity gives them extra time.

✓ TRUE FACT
Muons have a rest-frame lifetime of about 2.2 μs, but traveling near light speed, time dilation lets many reach the ground. At (0.998c), they can cover tens of kilometers before decaying.
