Oumuamua has obviously not finished talking about him. In his next book, Avi Loeb, a Harvard University astronomer, effectively puts a coin back in the machine by pointing to the body as the first sign of intelligent alien life.
Oumuamua, or rather 1I / Oumuamua, was detected for the very first time on October 19, 2017 and therefore three years ago.
By observing the solar system, Pan-STARRS 1 has effectively detected a body speeding along, a body coming from a system other than ours.
Oumuamua, between comet and extraterrestrial probe
Very quickly, all the scientists aimed their instruments at the object. They then realized that the latter had a very strange appearance, an appearance bringing it closer to the shape of a cigar spinning on itself. A feature that is totally incongruous and goes against everything we know about asteroids and comets.
The story does not end there, however. By observing the trajectory of the body, researchers were surprised to discover that the object had suddenly accelerated after passing by our star.
Oumuamua then found himself at the heart of many theories and if most researchers preferred to proceed with caution, Avi Loeb, for his part, did not hesitate to evoke the track of an alien spacecraft or probe.

Avi Loeb, the astronomer who dreams of other civilizations
A theory that has naturally earned him a lot of mockery. Mockery that probably did not dampen his enthusiasm.
As Publisher Weekly reports, Avi Loeb has indeed signed a new book, a book about Oumuamua and describing the object as “the very first sign of the existence of intelligence outside Earth” . In the book, which is not yet available on the market, the researcher indeed defends the theory according to which the body is potentially a piece of advanced technology created by an extraterrestrial civilization living in a distant system.
If the thesis can lead to a smile, it ultimately takes more exercise. Anne Wojcicki, the co-founder of 23andme, thinks that Loeb's new book is above all intended to show that scientific curiosity has many virtues, virtues necessary for our evolution and our development as an intelligent species.

An ode to scientific curiosity
It should still be pointed out, and this is important, that the theory of the extraterrestrial probe is not the only one which can explain the strange behavior of Oumuamua.
Some researchers believe that the body sheltered in its entrails pockets of ice and that it is these which caused the acceleration of the body when the latter passed near the Sun.
In short, exactly as a comet would have done.
