The discovery of an intelligent form of life outside our planet may be the biggest shift in the course of humankind, but what if scientists collectively decide to ignore the evidence pointing to it? Thus begins a new book by a prominent astronomer who argues that the simplest and best explanation for the unusual properties of an object that passed between the stars through our solar system in 2017 is that it was a technology designed by an alien object, according to Agence France-Presse.
Does it sound strange? Scientist Avi Loeb says the evidence shows otherwise, and he is convinced that his peers in the scientific community are so steeped in collective thinking that they are not ready to resort to the UCAM blade principle (a simple method of thinking, analysis, and conclusion without diving into complications).
It’s hard to dismiss the theory of Loeb, who was long the head of astronomy at Harvard, published hundreds of groundbreaking research papers and collaborated with greats like the late Stephen Hawking.
“The idea that we are unique and special is vanity,” the scientist said in a video interview. “The right approach is to be humble and say we’re not special. There are a lot of other cultures and we just need to find them.”
Loeb, 58, addressed his theory of the alien object “Oumuamua” (the Hawaiian explorer) in the book “Extraterrestrial: The First Sign of Intelligent Life Beyond Earth.”
The facts are as follows, in October 2017, astronomers noticed the existence of an object moving at great speed, and it was only possible that it came from another star, which is the first recorded case of an interstellar intruder.
It did not appear to be an ordinary rock because after setting off around the sun, it accelerated and veered from the expected path, driven by a mysterious force.
This could easily be explained if a comet expelled gas and debris, but there was no visible evidence of this “gas release” process.
The traveler also descended in a strange way, according to the method that made it brighter and dimmer in the scientists’ telescopes, and was unusually luminous, indicating that it was made of shiny metal.
In order to explain what happened, astronomers had to invent new theories such as that it was made of hydrogen ice, so it would have no visible effects or that it dissolved into a dust cloud.
“These ideas that came to explain the characteristics of Oumuamua always included something that we had not seen before,” Loeb said. “If this is the direction we take, why not think that it is an industrial origin?”
Oumuamua was not photographed up close during his short stay, as he discovered it as soon as it left our solar system.
There are two shapes that suit the distinct characteristics observed: long and thin, like a cigar, or flat and round, like a pancake.
Loeb notes that the simulations favor the second option, and he believes the object was intentionally built as a sail propelled by stellar radiation.
It was also surprising how the body moved, which made its passage even more strange.
Before colliding with our sun, “Oumuamua” was “at rest” by analogy with the neighboring stars, which is rare. Instead of thinking of it as a ship rushing through space, from the perspective of its shape, our solar system collided with it.
“Perhaps Oumuamua was like a buoy that rests in the vast expanse of the universe,” wrote Loeb.
The French Press Agency said that Loeb’s ideas put him at odds with his peers. Astrophysicist Ethan Siegel described him in “Forbes” magazine as “a scientist who was once respectable” but he failed to convince his peers of his arguments, so he began trying to convince the public.
For his part, Loeb protests the “bullying culture” in the academy that punishes people who question traditional belief, just as Galileo was punished when he suggested that the Earth is not the center of the universe.
Compared to speculative branches of theoretical physics, such as searching for dark matter or the multiverse, the search for the existence of aliens is a path that makes more sense to follow, he added.
That is why Loeb is pushing for a new branch of astronomy, “space archeology”, to search for the biological and technological signatures of extraterrestrials.
“If we find evidence of technologies that took a million years to develop, then we can get a shortcut to these technologies and use them on Earth,” said Loeb, who spent his childhood on a farmhouse reading philosophy.
Such a discovery could “give us the feeling that we are part of the same team” as humanity faces threats ranging from climate change to nuclear conflict.
He concluded: “Instead of fighting each other, as countries often do, we may be able to cooperate.”
