LITTLE LIGHTSynthetic illustration · Not a field observation result
Not seeing it does not mean it did not happen
Imagine a signal that stays at the same brightness. We observe only five out of every ten time points, leaving the others unobserved. If we fill every unobserved value with zero, the resulting sequence rises and falls regularly.
But that rhythm comes from how we observe, not necessarily from the signal itself.
Two causes, the same appearance in the data
- Scenario A: The signal is always present, but observation is intermittent.
- Scenario B: The signal itself appears periodically, and every time point is observed.
The final sequence of zeros and ones alone cannot distinguish these scenarios. This is a reproducible synthetic counterexample, not a conclusion about real firefly data.
Zero means “an observation was made and its value was zero.” Unknown means “there was not enough observation.” Convenience is not a reason to treat them as interchangeable.
The next step is not to rush into spectral analysis
First establish the time units, the mapping between the data and the original video, and which time points have valid observations. Where this information is incomplete, preserve unknown values rather than silently replacing them with zeros.
The illustration uses an artificially constructed sequence, with no field data loaded. It demonstrates a limit on inference, not proof that a rhythm in nature exists or does not exist.
