Harvard Scientist Suggests That Our Universe Was Created in a Laboratory

It was an otherwise non-notable day in October 2017 when Canadian astronomer Robert Weryk made an astonishing discovery.

Thanks to data from the University of Hawaii’s Pan-STARRS1 telescope at the Haleakala Observatory in Hawaii, Weryk spotted an unusual object, oblong and approximately the size of a football field, screaming through the solar system at 196,000 miles per hour. Strangest of all was that it seemed to be accelerating slightly, pushed by an invisible force that has yet to be fully explained.

Its highly unusual trajectory caused it to slingshot past our Sun, leading scientists to believe that the space object — later dubbed “‘Oumuamua,” or “scout” in Hawaiian — was the first ever visitor from outside our solar system to be observed directly.

Over the last three years, countless attempts have been made to explain ‘Oumuamua’s unprecedented characteristics. Some speculated that it was hydrogen iceberg, while others suggested it was a traveling space rock covered in a layer of “organic sunscreen.”

To Avi Loeb, astrophysicist and professor of science at Harvard University, the answer could be a tantalizing one. His controversial argument is that ‘Oumuamua may have been a probe sent by an extraterrestrial civilization — an explanation that’s garnered enormous attention in the media and, unsurprisingly, proved divisive among experts.

In his new book, titled “Extraterrestrial: The First Sign of Intelligent Life Beyond Earth,” Loeb explores his provocative hypothesis, using the story of ‘Oumuamua to lay the groundwork of a much greater conversation: the struggle to be taken seriously within a scientific community that has historically held the search for extraterrestrial intelligence at arm’s length.

During an interview with Futurism, Loeb argued that scientists’ explanations fell short of explaining ‘Oumuamua’s many quirks and eccentricities. The scientific community “advocated for something that we have never seen before,” he said.

One example of this was what Loeb referred to as the “dust bunny” hypothesis, which theorized that ‘Oumuamua’s odd trajectory could be explained by a very low density.

“The problem with that is I don’t think something of the size of a football field that is a dust bunny would survive a journey of millions of years through interstellar space,” Loeb said, vacuuming up that hypothesis. “I mean, I just don’t think that it can hold itself together.”

To Loeb, scientific explanations that attempted to squeeze ‘Oumuamua into an existing scientific framework just didn’t make sense.

“The point is, you can’t on the one hand say it’s natural,” Loeb argued, “and then whenever you try to actually explain it with natural processes, you come up with something that we have never seen before.”

And that’s how he ended up at aliens.

At the root of Loeb’s alien theory is that ‘Oumuamua may have been a solar sail sent to us from another star system.

In the simplest terms, a solar or light sail is a form of spacecraft propulsion that turns the low pressure of solar radiation into movement.  Earthling scientists have already experimented with the concept; in 2019, the non-profit Planetary Society launched a craft called LightSail-2, which uses 340 square feet of an extremely thin layer of reflective polyester film to gradually propel itself.

To Loeb, a solar sail being pushed by starlight could explain ‘Oumuamua’s unexpected acceleration. If it’s solid and isn’t a dust bunny, the astrophysicist concluded that the interstellar visitor must also be shockingly thin — perhaps, according to his calculations, “less than a millimeter thick.”

To the astronomer, the solar sail conclusion was following “footsteps, just like detective Sherlock Holmes. When you rule out all other possibilities, whatever you’re left with must be the truth.”

That conclusion is a stretch to many astronomers in the field, who have repeatedly challenged Loeb’s conclusion.

In a 2019 study published in the journal Nature Astronomy, an international team of researchers argued that they found “no compelling evidence to favor an alien explanation” for ‘Oumuamua.

“‘Oumuamua’s properties are consistent with a natural origin,” University of Maryland astronomer Matthew Knight, co-author of the study, told Reuters at the time, “and an alien explanation is unwarranted.”

Their argument was that ‘Oumuamua is a “planetesimal,” or a small fragment of a planetary building block that just happened to drift through our star system.

Weryk, who discovered the object in the first place, had no kind words for Loeb’s hypothesis. “Honestly, that’s a bit of wild speculation,” he told the CBC in 2018…
