Assertion: muon | /r/HasAspect | longer half-life
Facets:
value: due to their velocity
type: CAUSE
Source sentences:
text: at most (as seen from Earth) the time dilation effect of special relativity (from the viewpoint of the Earth) allows cosmic ray secondary muons to survive the flight to the Earth's surface, since in the Earth frame the muons have a longer half-life due to their velocity.
