Behind the scenes[[edit] | [edit source]]
The 2019 Companion Chronicles audio stories Daybreak and The Vardan Invasion of Mirth establish that fixed points in time are only created once a probability waveform has collapsed. This is a reference to wave function collapse, a concept in quantum mechanics. This is when a wave function in a superposition (ie. with multiple possible quantum states) is "observed" (measured), and thus collapses into only one possibility.
Ng in ScrapeJane is stretching this meaning of "observation", in the context of quantum mechanics. In the real world, a measurement in quantum mechanics is not usually taken to be the same thing as mere observation through sight. The Von Neumann–Wigner interpretation, treating the entire experimental apparatus as a single quantum state, would have an equivalent usage of the term, but this is the one outlier.
