Video insights

@bit_wonder's TikTok video "Time Dilation Saves a Muon 🎧 Why do muons from cosmic rays reach the ground? A muon lives only about 2.2 microseconds, just 660 m even at light speed, yet it crosses 15 km of air, because at 99.9% of light speed its clock runs about 24 times slower. A cosmic ray hits the air 15 km up and one muon races down: on the ground's clock the trip takes about 50 microseconds, on the muon's own clock about 2.1. Without time dilation only about 1 in 8 billion would make it; with it, about 2 in 5 do, and detectors catch around 10,000 per square metre every minute. From the muon's side its time is normal and the air is squashed 24 times thinner, to about 625 m, so both views agree it lands.
