Sphere is a 1987 novel by Michael Crichton, his sixth novel under his own name and his sixteenth overall. The story follows Norman Johnson, a psychologist engaged by the United States Navy, who joins a team of scientists assembled to examine a spacecraft of unknown origin discovered on the bottom of the Pacific Ocean. The novel begins as a science fiction story but quickly transforms into a psychological thriller, developing into an exploration of the nature of the human imagination.
Staying on subject, I wonder if we will see a new adaptation of ANDROMEDA STRAIN some time. As a story it seems topical and relevant.
Why apply concepts like "rogue", "mission", "rules", or even "individuals"? There's no guarantee such ideas mean anything to these things. For all we know, the UFOs themselves are not actual artificial spacecraft, but "biological" entities. Or autonomous drones.
Or they're not even extraterrestrial, but visitors from the future. Or some sort of interdimensional phenomenon. Or they're some sort of mythological being out of human religion- perhaps Abrahamic entities like the Angels of Mons. Or that they're the manifestation of mankind's collective unconsciousness, a sort of high-level tulpa. Or they're just some kind of weird unknown cosmic particle, a high-altitude form of quantum ball lightning.
Those possibilities are tongue-in-cheek, but my point is that if you're going to start assuming that UFOs are just spacecraft from an unknown alien race... then you start making assumptions upon assumptions and the whole thing just devolves into science fiction tropes. And honestly, those tropes are no more probable than the crazy Fortean explanations I've offered. It's fun to talk about, but why take these thought experiments seriously?
