Every now and then controversy renews about aliens … Do they really exist or do not exist? But Avi Loeb, an astrophysicist at Harvard University, said recently that he found good evidence of space technology in the solar system, but that some other scientists do not take his ideas seriously.
In his new book, Extraterrestrial: The First Sign of Intelligent Life Beyond Earth, Loeb describes his journey with an interstellar space visitor called Oumuamua, as it blasted through our solar system in 2017.
The physicist believes, “It is possible that the solar system was visited by a strange light sail, perhaps like space waste, but by an intelligent space civilization that is not on Earth.”
