This is an interview with the astronomer Karen Meech discussing the reasons why she doesn’t think Aumuamua is of alien origin. It seems the nut of the question, besides the inexplicable acceleration, is the shape of the object. She presents an image of a light reading taken that seems to indicate a cigar shaped geometry, not a flat one. This runs counter to the above linked articles claim that it’s 91% certainly flat.
One thing that jumped out to me. She used a term, I don’t have time to pinpoint it at the moment, where she says something to the effect that the notion of it being flat is “impossible” or something. Essentially saying because such a shape would be so out of the realm of what is considered possible that it shouldn’t be considered. This strikes me as an unjustified assumption, the entire point is that the thing doesn’t look or act like any other object we have seen.
When it comes to UFOs, there’s little that surprises Nick Pope these days. The former British civil servant spent 21 years at the Ministry of Defence (MOD) and between 1991 and 1994 was assigned to its highly classified ‘UFO desk’, charged with looking into reports of Unidentified Aerial Phenomena, or UAPs, a phrase Pope adopted internally to get away from the “pop-culture baggage” associated with the term UFO. It wasn’t your average job. “The remit was to investigate all sightings in the United Kingdom air defence region and assess whether there was evidence of any threat,” Pope explains.
The Cold War had come to an end but that didn’t mean that unknown, advanced technologies from a hostile state couldn’t be out there testing the UK’s capabilities. And if they were, the MOD wanted to know about it. While Pope was in charge he would receive around 300 reports a year. Most had a rational explanation. Meteors or misidentified planes. Satellites or weather balloon
sin and
need sine and cosine
per se; what it actually does is
rotate a point around the origin in two nested loops, and also rotate two
angles just for the animation. If you’ll recall from the other article, the
inner loop is just plotting dots in a circle, which goes around another, larger
circle. In each loop, the sine/cosine terms are just moving by a small, fixed
angle.
So we don’t need to track the
angle at all, we only need to start at cos=1,
sin=0 and rotate a circle around the origin to generate all the sines and
