Avi Loeb is nothing less than the director of the Department of Astronomy at Harvard University. And he believes that the asteroid Oumuamua could well be an alien vessel ...
The asteroid Oumuamua (which means "scout" in Hawaiian) is the first object that has been observed in our solar system without originating there. It was spotted in October 2017 by the Hawaii Observatory when it was located some 30 million kilometers from Earth.
The astrophysicist, who was nevertheless named one of Time's 25 most influential people in space studies, published an article in The Astrophysical Journal Letters, a leading journal.
In his text, he explains that he partly took up discussions he had with colleagues who, themselves, think that this object has really special characteristics, but none has dared to speak about it publicly.
A strange shape
Initially, we saw the Oumuamua as a comet. Except that comets are made of ice that evaporate as they get closer to the sun and create a trail of dust or gas. But not Oumuamua.
We then cataloged the object as an asteroid, a piece of rock! For eight hours, the pebble has been spinning. And the scientist explains that, during this period of time, the changes in luminosity were made on a scale of 10. Except that the factor is 3 for asteroids… In layman language, that means that its length is 10 times greater than its thickness. And Avi Loeb points out, "This extreme geometry can only be translated in two ways: either the object in the shape of a cigar, or it is flat like a pancake." Basically, the asteroid has a much more elongated shape than all of the stellar objects listed around us.

An object that accelerates
Last June, the Hubble Orbiting Telescope collected new data that showed Oumuamua had accelerated on entering the solar system! And the gravitational force of the Sun does not explain this acceleration. The other explanation comes down to the comet theory. But, once again, no shows were shown. And Oumuamua's shape was not affected, which would automatically have been the case if it had been a comet.
Avi Loeb's explanation? The object received an external thrust! For him, it was the solar radiation captured by the object that allowed him such an acceleration. This would mean that Oumuamua would be less than a millimeter thick (the shape of a pancake!) "Moreover, it is known to be 10 times brighter than a classic asteroid. So we have a thin, flat and shiny object. I came to the conclusion that it could be a solar sail, ”he says. In other words, a ship would use solar radiation to move forward instead of any fuel.
The researcher knows what he is talking about because he has worked on the subject with Stephen Hawking, Mark Zuckerberg and Yuri Milner (investor). They created the Breakthrough Starshot initiative to create solar sails that could reach Alpha Centauri in less than 20 years. And according to Avi Loeb's calculations, the acceleration of Oumuamua would be comparable to such a sail close to the sun.
A probe?
For Avi Loeb, Oumuamua would be a probe sent into the universe at random or on the contrary to our system and it could have drifted for millions of years. SETI studied the asteroid, but did not detect any radio broadcasts
To confirm this whole story, we will have to wait for the end of the construction of the LSST telescope in three years. This synoptic study telescope, which will be located at an altitude of more than 2,600 meters in Chile, will make it possible to observe other objects originating from other systems and to verify whether Oumuamua, which has disappeared from our radars, was an exception ...
