How subatomic particles prove that time actually slows down
In short: Muons are tiny particles from space that shouldn't survive long enough to reach the ground. Yet, they do. This video explains how their journey provides tangible evidence for Einstein's theories of relativity.
Terrestrial muons serve as a primary experimental proof for special relativity, specifically demonstrating time dilation and length contraction. Because these particles are produced by cosmic rays—which hit the atmosphere with greater intensity at the poles—they travel toward Earth from high altitudes.
The mystery lies in their lifespan: muons have an exponential decay and a mean lifetime that is typically too short to allow them to reach the surface before disappearing. Their presence on the ground confirms that, from our perspective, their internal clocks slow down as they move at near-light speeds.
