Thanks. Watched about half of it, up to the speculation on Von Neuman probes. (had to watch without sound...automated captions are entertaining - Lick Observatory was captioned as "leak observatory") Some interesting hypothesizing on such objects. UAO seems like a good name for them, unidentified astronomical object.
If it's an ET artifact, then it's also a question of how distant (far enough that it shows as point images without any elongation along their trajectory) and if it is entering or leaving the solar system. The odds that any object's trajectory would be straight at Earth are extremely small, even if Earth is its destination. After all, a trip to Earth would involve first a path of deceleration, then a solar orbital insertion of some kind, then an Earth orbital insertion, with maybe some kind of maneuver like a Hohmann transfer or a lower energy transfer. Or it could be some kind of fly-by, without an Earth orbital insertion. A lot depends on the delta-v budget, as it's called, i.e. the amount of fuel available and the thrust it produces. Unless it's using some kind of solar sail, or other externally derived energy. I think the video mentions some speculation about an object that is quite flat and thin, which happens briefly to have its reflecting face pointed at the Earth observatory.
What's needed are more UAOs spotted and recorded, to maybe narrow down some of this meandering speculation. Same old same old.
