LOW COMEDY

"Still Rama, bitchez"

MIDDLE COMEDY

Avi Loeb dismissively deals with the "100% pure nitrogen" argument in his book, which came out what, six months ago? by pointing out that we've never seen this before despite our observation of 25 new comets a year.

Also unaddressed by the "it's just a rock" hypothesis is the utter and total dependence on a non-spherical shape in order to justify the solar behavior contradicted by the implied torque necessary to accomplish that. Short version, it's 100% uniform nitrogen ice that happens to outgas in a decidedly non-uniform way. Not only that, but the amount of cometary outgassing did not change in any way as 'Oumuamua looped around inside the orbit of Mercury, because the torque didn't change, the period of albedo oscillation didn't change, nothing changed despite models requiring 'Oumuamua to shed twenty percent of its mass in the process.

Further, most natural hypotheses tend to wave their hands over terms like "In terms of speed, the object entered the solar system at a velocity a bit lower than would be expected" rather than address the fact that 'Oumuamua hit the solar system at Local Standard of Rest:

    'Oumuamua originated from a very special frame of reference, the so-called local standard of rest (LSR), which is defined by averaging the random motions of all the stars in the vicinity of the sun. Only one star in 500 is moving as slowly as ‘Oumuamua in that frame. The LSR is the ideal frame for camouflage, namely for hiding the origins of an object and avoiding its association with any particular star. The relative motion between ‘Oumuamua and the sun reflects the motion of the sun relative to the LSR. ‘Oumuamua is like a buoy sitting at rest on the surface of the ocean, with the solar system running into it like a fast ship. Could there be an array of buoys that serves as a network of relay stations or road posts, defining the average galactic frame of reference in interstellar space?

HIGH COMEDY

Loeb's basic argument is that the scientific community will bend over backwards to avoid heresy. From a probabilistic standpoint, his argument is that investigating 'Oumuamua from the hypothesis that it is artificial requires far less exotic "model the horse as a sphere" thinking than investigating it from a natural standpoint, yet you can't investigate it from an artificial standpoint without the Daily Mail camping on your lawn and your colleagues accusing you of Little Green Men hysteria. "If you assume heretofore undiscovered exotic material and ignore 70% of the objections to our hypothesis, it makes total sense" is the basic standpoint of the entire scientific community while "LOL you believe in space aliens" is the basic standpoint of the media, while Loeb is rightly pointing out that we're an investment away from throwing 'Oumuamuas into the cosmos for a couple hundred grand each.
