These are the facts: A pancake-like object the size of a football field seems to be pushed by a force that is not related to a cometary tail. The best fit for the light curve we saw was a flat object, pancake-like. That means that it has an extreme geometry that is at least ten times longer than it is wide, because as it’s spinning around, you’re seeing the area that reflects sunlight changing by a factor of ten. ‘Oumuamua was tumbling and spinning, and the brightness varied by a factor of ten as it was tumbling every eight hours. Here is an object that we can identify as artificially made, that we produced it, and it behaves in a similar way to ‘Oumuamua. It was found that the object is actually a rocket booster from a launch of a lunar lander in 1966. In September 2020, there was another object that exhibited an extra push without the cometary tail. So what gave it this push remains a mystery. The only problem is this extra push was not accompanied by a cometary tail. When gases evaporate, and go in one direction, they push the object in the opposite direction, just like a jet plane. Usually with comets, you get this extra push from the cometary tail, the rocket effect. When this object was analyzed, it looked like there was an extra push on it, in addition to the force of gravity from the sun. It was clearly coming from interstellar space. It moved too fast to be bound to the sun. It was the very first object spotted near the earth that came from outside our solar system. The object was discovered by the Pan-STARRS telescope in Hawaii and was given the name ‘Oumuamua, which means a scout or a messenger from far away in the Hawaiian language. What do you think passed by the earth in November 2017? Intelligencer chatted with Loeb about his theories on ‘Oumuamua, other recent claims from high-profile figures about the existence of aliens, and how the scientific community is responding to his bold claims. “Given so many worlds … with similar life-friendly conditions, it’s very likely that intelligent organisms have evolved elsewhere.” The opposition to even the mere concept of extraterrestrial life, Loeb contends, “boils down to conservatism, which many scientists adopt in order to minimize the number of mistakes they make during their careers.” “Overall, about a quarter of our galaxy’s 200 billion stars are orbited by planets that are habitable the way Earth is, with surface conditions that allow liquid water and the chemistry of life as we know it,” he writes. In his new book, Extraterrestrial: The First Sign of Intelligent Life Beyond Earth, which comes out on January 26, Loeb makes a persuasive scientific argument about ‘Oumuamua’s otherworldly origins, and delves into why his peers have been so hostile to the idea of life outside of Earth. He’s an astrophysicist who has been teaching astronomy at Harvard since 1993, and chaired its astronomy department for nine years. Before you discount Loeb, you should know that he isn’t the average UFO-spotting kook you might see on a rerun of Unsolved Mysteries. Avi Loeb to hypothesize that ‘Oumuamua was artificially made, perhaps a piece of technology or some debris from a faraway alien civilization. It moved too fast for it to have come from our solar system, its orbit was unusual, and it didn’t have any of the traditional markings of an asteroid or comet. Spotted by a telescope in Hawaii, this strange thing was dubbed ‘Oumuamua. In November 2017, an object passed by our planet that was unlike anything astronomers had ever seen.
