A scientist at Harvard University who said that the mysterious subject that briefly traveled through our solar system between 2017 and 2018 may be a strange spacecraft, he argues.
An object of approximately 400 meters long, 40 meters wide, was called Oumuamua, from the Hawaiian word that refers to the messenger from afar.
It was first seen in October 2017, moving at unusually fast speeds of more than 87 kilometers per second and leaving our solar system three months later.
In addition to speed, Stargazers attracted attention with their special shape and motion pattern, which was not based on the gravitational pull of the sun or planets.
Abraham Loeb, chair of the Harvard Astronomy Department, wrote in the spring of last week that he was "a full-featured probe sent deliberately to the surrounding country by the civilization of an alien."
Loeb and co-author Shmuel Bialy suggested that the subject could be a light sail that could theoretically move around the space under the light or solar energy.
Their claims were widely questioned by other astronomers. Paul Delaney of York University in Toronto claimed that Loeb and Bielay "did a little" by indicating that Oumuamu was artificially created.
"Yes, is it a probability?" No, "Delaney said last November.
The scientist who first discovered Oumuamu also separated from Loeb's theory and called his comments "wild speculation."
Loeb does not seem to have resorted. The face of these allegations is that it overestimates the idea that is theoretically possible, but realistically unlikely.
In an interview with Israeli newspapers, Haaretz said Loeb wrote an article because he believed in his conclusions, not in an attempt at publicity.
"Senior scientists have said this object is special, but they are afraid they will publish their thoughts," he said.
Loeb said he could "commit suicidal images," if sometimes more natural explanations for Oumuamu had ever worked. Still, he remained firm in his belief that Oumuamu may be the result of a "fishing expedition" from another solar system – much like the artificially created Voyager probes that set out on Earth in 1977.
NASA says that Oumuamu certainly comes from a different solar system and can spend hundreds of millions of years before coming into our solar system. It reserves what an object can actually be.
Loeb also co-authored the new "Turning the Heat On Oumuamua," in which he and other Harvard astronomers attempt to find out what interstellar objects like Oumuam are in our solar system.
According to their model, approximately two objects from the outside of the solar system go through Mercury's orbit every year, and some of these objects hit the sun at about every 30 years.
These objects are typically asteroids and comets that the scientific community understands much better than Oumuamu.
