AstroWright blog posts on 3I/ATLAS and Avi Loeb's claims (September to December 2025)
Jason T. Wright, 2025. AstroWright (Pennsylvania State University blog).
A series of posts by a Penn State astronomer and SETI researcher answering Loeb's 3I/ATLAS claims one by one: that anti-tails from large grains are known (Comet Kohoutek 1974, C/2014 UN271), that the quoted acceleration uncertainty was three to four orders of magnitude too small, that the Hubble size limit stands, and that the "anomalies" are the ordinary oddities of a comet from another system. Posts dated 2, 29 September; 24 October; 9, 14 November; 7 December 2025.
What it's used for here
The clearest point-by-point response to the 3I claims; a blog, not a paper, and cited as such.
