Conclusion:
In this scenario, there is but one single muon with one single life.
The muon lives from its creation to its decay.
This single life is measured to last 1 μs in the muon frame K,
and is measured to last 47.3 μs in the Earth-frame K'.

The hardest thing for the novice to understand is that this phenomenon is reciprocal.
For the muon, a phenomenon that occurs in the laboratory for 1 µs would last for him...
This confuses the novice.
He doesn't understand how this can work.
But we can't blame them; the bigwigs are just as lost when Doctor Hachel starts talking about modern relativity theory. They can't understand that when Stella makes her U-turn, over there, at 12 ly, and returns to Earth at 0.8c (the Langevin traveler), she is stationary in her frame of reference but sees the Earth coming back towards her, with an apparent speed of 4c, for 9 years (so far, so good). And THEREFORE, she sees the Earth coming back towards her over a distance of 36 light-years (inverse distance contraction).
This drives them all crazy.
