I took it that they’re reporting the info they got from the astronomers/scientists. This whole ‘possible alien spacecraft’ farce started from them, right?
Much of this is nonsense such as an “interstellar comet” as there is really no such thing as they would disintegrate over the tens of thousands of years it would take for a single straight line trip. Astronomers and astrophysicists would never make such a foolish comment.
