Here We Go Again! Controversial Paper Questions Whether Interstellar Visitor 3I/ATLAS Is 'Possibly Hostile' Alien Tech in Disguise

SOLAR SYSTEM, JUL 22 – Harvard physicist Avi Loeb argues 3I/ATLAS's unusual features suggest it may be alien technology with a 0.005% chance of random planetary alignment, challenging its comet classification.

  • On July 1, astronomers detected the interstellar object 3I/ATLAS, which some researchers suggest may have a non-natural origin, raising questions about its nature.
  • In a new paper, Loeb and co-authors questioned whether 3I/ATLAS is an alien probe, building on his prior suggestion that 'Oumuamua may be alien technology.'
  • Traveling at 245,000 km/h, its orbit brings it within 0.65 au of Venus, 0.19 au of Mars, and 0.36 au of Jupiter, with a 0.005 percent chance of that triple encounter.
  • Richard Moissl, Head of Planetary Defence at the European Space Agency, said, 'There have been no signs pointing to non-natural origins of 3I/ATLAS in the available observations.'
  • Avi Loeb notes that on October 29, it will reach perihelion, hidden from Earth's view, and finds this timing suspicious.

Avi Loeb has done so again. The appearance of 3I/Atlas, in fact, the third interstellar object detected by man, has given new ammunition to Harvard’s famous astrophysicist to fuel his controversial theses. And although astronomers believe that it could be a comet, Loeb, in collaboration with Adam Hibberd and Adam Crowl, both members of the London Interstellar Studies Initiative, has just raised in a new study the intriguing possibility that 3I/A…
