But how is the lab frame different from the rest frame in which the muon is is observed as moving? They seem like the same frame. AG -- *You've confused yourself by not mentioning it's motion in the lab frame, which is implicitly zero.* So it's comparing the half-life in the muon's frame with the muon's half-life as it travels at near light speed. *How is sitting in a lab observing the muons fly by, different from sitting atop a mountain watching them fly by? AG * *I wonder why I bother to write answers, when you don't even read the first line. Brent* *You're mistaken, totally. I read your message. ISTM, the frame atop the mountain is at rest and the muons fly by, whereas the earth bound lab is in the same situation. AG* *It says "...motion in the lab frame...is zero". And apparently you didn't look at the diagram at all. Brent* *I glanced at the diagrams. In the lab frame, the muons are moving toward the Earth's surface and beyond, through the Earth, so I see them as moving in the lab frame. Same atop the mountain.
