The main professor of Astrophysics at Harvard University, the Israeli-American Abraham ‘Avi’ Loeb, is convinced that there is intelligent life outside of Earth. This theory supports it in his book “Extraterrestrial: The first sign of intelligent life beyond Earth”, which will be published simultaneously in about twenty countries.
In his work, the prestigious academic defends the idea that Oumuamua, a curious interstellar object observed while crossing the Solar System, is not a rock detached from other stars, but is the “first sign of intelligent life of extraterrestrial origin”, a theory that the astronomer presents for the first time to the general public.
According to Loeb, the characteristics of the space object only allow one explanation: “Oumuamua, as they called it, constitutes the first evidence of extraterrestrial life and technology, and the implications of this statement for humans are immeasurable.”
The interstellar body, which was detected moving close to Earth on October 19, 2017 by the Canadian Robert Weryk, was initially classified as a comet and finally as an asteroid, although its shape and behavior differed from these types of astronomical objects.
The characteristics of Oumuamua
Among his arguments, Loeb assures that Oumuamua It is not a comet because it does not leave a trail – also known as a coma – nor does it have the shape of an asteroid, since it is elongated, an aspect that had not been previously observed in this type of space body. In addition, it does not have a precise orbit and can change speed, a background that science is still trying to explain.
Oumuamua, which in Hawaiian means ‘first messenger from another world’, is an object that comes from outside the Solar System, of unknown origin and that has never been seen before. When Loeb suggested that it was the first evidence of extraterrestrial life and technology in space, it sparked what is probably the most relevant scientific debate in decades.
The composition of the space object had also been discussed. It was believed to be made of molecular hydrogen ice, which would have explained its unusual change in speed. However, this same theory was rejected by Loeb, who believes that Oumuamua is actually a spaceship that had not worked for a long time, that it fulfilled its mission and that continues its journey, inertly, through space.
Many Astrophysicists, including Loeb, will unfortunately have many unanswered questions: the object is very far from ground-based telescopes.
