Both timelines start together. Length measures elapsed time, not a physical distance.
A little perspective
Muon lifetime lasts about 22 times as long as 100 nanoseconds.

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.

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.

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.
- Comparing
- Time ↔ Mean lifetime
- Relative size
- Muon lifetime is larger on this measurement by a factor of about 22.
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.
