Avi Loeb has argued that 3I/ATLAS shows multiple anomalies — non-gravitational acceleration, large-scale jets/coma extending hundreds of thousands to millions of kilometers, unusual composition and ch...
Avi Loeb argues that 3I/ATLAS shows a cluster of anomalies that could be consistent with an artificial origin and has urged targeted observational tests to check for technology, while the broader comm...
Scientific observations and expert analysis conclude that 3I/ATLAS is an interstellar comet exhibiting natural cometary behaviour—outgassing, coma formation, and a hyperbolic trajectory—rather than en...
Avi Loeb’s public claims that the interstellar object 3I/ATLAS could be a technological artifact have drawn a split response: , while Loeb and some allies press for further scrutiny and greater data t...
Avi Loeb argues that multiple anomalous features of interstellar object 3I/ATLAS collectively point toward a possible artificial origin rather than a purely natural cometary body. His core evidence se...
A clear, peer-reviewed scientific consensus rejecting or confirming Avi Loeb’s claim that 3I/ATLAS is an artificial, technological object does not exist; the published, peer-reviewed literature to dat...
Avi Loeb publicly argues that interstellar object 3I/ATLAS could be a rather than a natural comet, a claim that has renewed debate over evidence standards and scientific norms . Independent astronomer...
The balance of observational evidence and expert analysis identifies 3I/ATLAS as an interstellar comet, not an alien ship: multiple telescopes and spacecraft recorded cometary behavior and chemistry c...
Scientists have not produced confirmed evidence of intelligent extraterrestrial life: a recent synthesis of seven decades of searches concludes “no confirmed evidence of extraterrestrial intelligence ...
Avi Loeb has publicly argued that 3I/ATLAS displays multiple “anomalies” — including non-gravitational acceleration, unusually long collimated jets/anti-tail behavior, rapid brightening and unusual co...
Avi Loeb has pointed to a set of observational anomalies—primarily a measured non-gravitational acceleration, unusual brightness and color behavior, and an atypical orbital geometry—as the basis for t...
The claim that 3I/ATLAS is an alien spaceship is false based on the weight of current astronomical evidence: multiple observatories and space agencies characterize 3I/ATLAS as an interstellar comet sh...
Avi Loeb has repeatedly raised the possibility that the interstellar object 3I/ATLAS could show *signatures consistent with artificial origin*, but he has not issued a single categorical statement dec...
Three competing narratives have emerged to explain 3I/ATLAS’s oddities: an astrogeological origin as a lithified, stratified siliciclastic fragment from an exoplanetary sedimentary basin (the “sedimen...
Conclusive evidence that an interstellar object is technological would require direct, unambiguous technosignatures — for example controlled radio transmissions, spectral lines indicating manufactured...
3I/ATLAS is an interstellar comet discovered by ATLAS in July 2025 that reached perihelion around Oct. 29–30, 2025 at roughly 1.4 AU from the Sun and made a closest approach to Earth of about 1.8 AU o...
The recent media swirl contrasts two very different visitors: interstellar 3I/ATLAS — widely discussed as “weird” and even possibly artificial by some commentators — and the Solar System newcomer C/20...
Available reporting shows 3I/ATLAS is an interstellar comet confirmed to be brightening unexpectedly as it passed perihelion on 29 October 2025 and then “speeding away” from the Sun; multiple outlets ...
Elon Musk has made joking and speculative comments about extraterrestrials in two different contexts: playful self-descriptions as a “time‑travelling, vampire alien” on his X profile and social posts ...
Claims that “aliens are real” or that an alien spacecraft will attack Earth in November 2025 rest on a mix of speculative scientific hypothesis, sensational media coverage, and fringe commentary; main...
