Harvard physicist cases on how ‘Oumuamu could have been an alien spacecraft

A physicist has weighed the mystery surrounding the interstellar object ‘Oumuamua’, which flew past the Earth at an unusually high speed in 2017.

Harvard professor Avi Loeb commented during an interview with Salon that it is possible that the sharp, cigar-shaped object was an interstellar spacecraft.

“At first, astronomers believed it to be a comet, because these are the objects that are most closely bound by stars,” Loeb said. “The problem with this was that there was no comic tail.”

Loeb wrote a book on the subject, titled: “Extraterrestrial: The First Sign of Intelligent Life Beyond Earth.” The book is set for release next week.

“Some people say, ‘Well this is not a comet, maybe it’s just a rock.” But the problem is that about half a year later, it was reported that there was an additional push by the Sun in addition to the force of gravity, “that continued.” This demonstrated some additional force. Usually that strength comes from the rocket effect of the comical tale, but there was no comic tail. So the question was, what creates this extra push? “

Loeb told the website that another item was detected, demonstrating an additional push called the 2020-SO, which he said ended up being a rocket booster from a failed mission to the lunar lander, Surveyor II called Was launched in 1966. He said that because this object was created artificially and had no comic markings, it “provides evidence” that we can tell the difference between a rock and an object – like a rocket booster – that is part of the Sun. Is pushed by light.

He told Salon, “For me, it demonstrated that maybe ‘Oumuamua was artificial, definitely not made by us because it’s only close to a few months. We don’t chase it with our best rockets either. Can.”

Loeb said it was “at the shinier end of all the objects we’ve seen from the solar system.”

In November 2018, a study published by Loeb and others at the Harvard Smithsonian Center for Astrophysics suggested that ‘Oumuamua may have been “a light of artificial origin” sent from another civilization. However, researchers, who discovered ‘Oumuamua’, the Canadian physicist and astronomer Robert Wreck, said it was the idea of ​​another civilization “wild speculation”.


‘Oumuamua, meaning “Pathfinder” or “Scout” in Hawaii, was first classified as an asteroid when it was spotted at 196,000 mph in 2017. However, it was recently found to be more similar to a comet.

NASA confirmed that it was “the first object seen in our solar system that originated elsewhere.”
