“Independently, our current knowledge of physics strongly suggests that interstellar travelers arriving in this solar system would be visible (during deceleration) to any serious observation of the night sky, whether Mayan, Ptolemaic, Galilean, or modern. The absence of any record that suggests arrival is strong evidence against interstellar aliens.”
Just curious:
Does human kind has in place 24⁄7 surveillance of every part of the sky around the globe? Citation?
Close enough to see the kind of effect that would be present from decelerating from interstellar speeds, assuming that aliens noticed us sometime after we made electromagnetic fields that exceeded background noise in orbit.
