Paris – In 2017, the passage of a strange object through our solar system baffled astronomers, and some considered it a sign of the existence of extraterrestrial life, a hypothesis that sparked controversy, but the Well-known scientist Avi Loeb defended it in a book published worldwide Thursday.
“If I’m right, it’s the greatest discovery in human history,” wrote Avi Loeb, director of Harvard University’s Department of Astronomy, on the red advertising tape in which the House of French edition “Lucoy” wrapped his book.
In his book confirming the observation of the “first sign of intelligent life off the planet”, the black hole specialist looks at the discovery of “Oumuamua”, a cigar-shaped object through our solar system at full speed in October 2017.
Oumuamua is 400 meters long and 40 meters wide. It was observed by the Pan-Stars 1 Telescope in Hawaii, and its speed was very high, which means that its source is a distant star, and it was the first object to be discovered, coming from another star system. .
He described this for an object first as an asteroid, then a team from the European Space Agency suggested it was a comet ejected from another star system.
But the hypothesis did not convince Avi Loeb, because he considered that it did not bear an explanation for the excessive acceleration of this object, nor because it did not release any trace (gas or dust) during of its passage near the sun, nor for its unusual shape.
Loeb and another Harvard researcher wrote an article in Astrophysical Journal Letters in which he considered that “Oumuamua” could only be a probe launched by an extraterrestrial civilization.
