Astronomers discovered the asteroid "Oumuamua, which traveled through our solar system after arriving from another star. While the asteroid is in the form of a cigar through our solar system, scientists began to theorize that asteroids could come from far and then remain. always discussing the discovery, a recent theory by experts from Harvard's Smithsonian Center for Astrophysics, Shmuel Bialy and Abraham Loeb, said that "Oumuamua could send aliens to see other galaxies.
Professor Loeb told the universe today: "We explain the surplus acceleration" Oumuamua "from the sun as a result of the force that sunlight exerts on its surface.
"For this power to explain the measured excess acceleration, the object must be very thin to determine a part of a millimeter in thickness, but a size of ten meters.
"For this reason, the object is light for the surface and allows it to function as a light sail.
"Its source can be natural (in interstellar media or protoprocesive disks) or artificial (as a probe sent to a reconnaissance mission into an internal region of the solar system)."
However, the astronomer, who discovered the asteroid Robert Weryk, criticized the outer theory that they call "wild" and "exotic".
Mr Weryk told CBC's Afternoon Drive: "I think it's a remnant from another solar system. It's just something that happened to come across us, and we were very happy that we were already doing that telescope and look in this direction.
"Theoretically, it has been announced for decades, but we have not seen it yet until we see another, there are many issues that we can not answer."
Other astronomers also criticized the theory of Professor Loeb.
Alan Fitzsimmons, an astrophysicist at the University of Queens in Belfast, recently stated: "Like most scientists, I would like to be convincing evidence of foreign lives, but that's not it.
"It has already been proven that its notable characteristics are consistent with a comet-like body that is excluded from the second star system.
"And some arguments in this study are based on a number with great uncertainties."
Katie Mack, an astrophysicist in North Carolina, also had a problem with theory.
She wrote on Twitter: "The thing to understand is that scientists are absolutely happy to publish a weird idea if it has even the smallest chance that it is not wrong
"But as long as each other option is exhausted for a dozen times, even the authors will probably not believe it."
It is likely that the bizarre space rock in the form of a cigar cost hundreds of millions of years and is the first foreign object found in our solar system.
"The Oumuamua is about 400 meters long and is a dark red color seen by the Pan-STARRS1 telescope in Hawaii on October 19, 2017 and travels to about 95,000 kilometers per hour.
