Both timelines start together. Length measures elapsed time, not a physical distance.
A little perspective
Muon lifetime lasts about 2.2 times as long as 1 microsecond.

Muon lifetime
A free positive muon has a mean lifetime of about 2.197 microseconds before decay. This is a statistical mean, not an identical lifetime for every muon.
Particle Data Group — Muon properties
The marked mean lifetime is calibrated. Unmeasured illustration details are representative.

Why these numbers?
The visual compares time with mean lifetime. The records below preserve each value’s basis and caveats.

- Comparing
- Time ↔ Mean lifetime
- Relative size
- Muon lifetime is larger on this measurement by a factor of about 2.2. Muon lifetime's selected measurement is approximately 120% greater than 1 microsecond's.
How to read the visual
The labelled spans and stored measurements determine the scale; unmeasured illustration details do not.
- Muon lifetime uses a 2.197 µs central value within a recorded range of 2.197 µs–2.197 µs.
- Muon lifetime is labelled measured; treat the displayed value as a comparison anchor rather than false precision.
