Good grief — he just can’t help himself! Classic narcissist. Everyone’s fav* Harvard astronomer has struck again! This has to be, as we call it here in Australia …. ‘taking the piss’, right? RIGHT?!?!?! HT SpaceFam pvt chat and someone that Loeb already has once tried to take on lmao

Abstract from new paper that features Avi Loeb as an author: At this early stage of its passage through our Solar System, 3I/ATLAS, the recently discovered interstellar interloper, has displayed various anomalous characteristics, determined from photometric and astrometric observations. As largely a pedagogical exercise, in this paper we present additional analysis into the astrodynamics of 3I/ATLAS, and hypothesize that this object could be technological, and possibly hostile as would be expected from the 'Dark Forest' resolution to the 'Fermi Paradox'. We show that 3I/ATLAS approaches surprisingly close to Venus, Mars and Jupiter, with a probability of ≲0.005\%. Furthermore the low retrograde tilt of 3I/ATLAS's orbital plane to the ecliptic offers various benefits to an Extra-terrestrial Intelligence (ETI), since it allows the object access to our planet with relative impunity. The eclipse by the Sun from Earth of 3I/ATLAS at perihelion, would allow it to conduct a clandestine reverse Solar Oberth Manoeuvre, an optimal high-thrust strategy for interstellar spacecraft to brake and stay bound to the Sun. An optimal intercept of Earth would entail an arrival in late November/early December of 2025, and also, a non-gravitational acceleration of ∼5.9×10−5 au day−2, normalized at 1 au from the Sun, would indicate an intent to intercept the planet Jupiter, not far off its path, and a strategy to rendezvous with it after perihelion.

He got his " minutes of fame " when SiriusXM/CNN's Michael Smerconish had Loeb on the show the last time Loeb lobbed this "hand grenade" into Astronomy. "This guy is no kook" Smerconish kept emphasizing. My thought was "Erich von Däniken strikes again." Still is with this.

They lost me with the first half sentence of the abstract. Calling its last few months before perihelion the "early stages" of its passage through the solar system shows they don't really understand what the solar system looks like, so how can they be trusted to recognize alien spaceships?

It's always kind of telling when someone just dumps a mass of declarations at you instead of focusing on a single topic. It seems to be common for people trying to push crackpot theories. They just yell an incoherent pile of statements and hope some part of it catches on.

Yup. Because it takes more time to disprove a claim or give a coherent explanation than it takes to shoot off another claim. That's why clickbaity and dismissive one-liners generally get more views than good explanations, even if the one-liners make no sense.
