Re: How long is a muon when at rest?

A muon originates in the upper atmosphere and arrives at sea level,
doesn't it? Simultaneously, light from the sun will catch up with and
pass the back end of the muon, gradually overtaking the muon as it
goes (in our frame of reference), reflect at sea level (which is where
the front of muon now is, since it has been hurtling down at near light
speed) and then takes the same amount of time to travel upwards from
the front of the muon to the back of the muon because the speed of
light in the muon's frame of reference is invariant. Doesn't this imply
that the muon's length in its own frame of reference is very nearly
from upper atmosphere to ground level?
