And

But with a little additional data, the model flipped and pointed to chamber deflation instead.
Does lend a grain of salt toward the military theory.
"“They're too nice; they're too perfect to be nature,”"
Nature does on occasion surprise us with nice clean signals; for instance, the history of pulsars, where the initial signals were so clean that people couldn't help but suspect they were artificial (and I do not mock them for that, it was a reasonable thing to put on the initial pile of theories): https://en.wikipedia.org/wiki/Pulsar#History_of_observation
The universe is still low-entropy, and will remain so for the forseeable future. Things like this can still naturally happen.
