Oumuamua | Discourse surrounding the intrinsic object of "alien" origin Technology and Science Science

The scientific article was signed by two researchers at Harvard University caused the mix this week, arguing that a huge elongated rock passes through the solar system may have sent foreigners.

"Oumuamua"as was called, was discovered in October 2017 by the Pan-STARRS1 telescope in Hawaii, so its name, which means" messenger "in Hawaii, is about 400 meters long and 40 meters wide and is registered with more than one telescope as the first well-known object of the second star system.

When the European Space Agency estimates in June as an asteroid, it is likely to have a comet (whereby the ice will be gas near the sun).

But according to these Harvard researchers, the "exotic scenario" means that "Oumuamua can be a fully functioning trial that is deliberately sent to the globe by a foreign civilization," they write in an article published 12. November. in Astrophysical Journal Letters.

The idea quickly ignited Twitter and the scientific community.

The reason for this assumption is that Oumuamua moves faster than expected. "At present, there is an unexplainable phenomenon, namely the Oumuamua acceleration, which we show, explains solar radiation pressure," Harvard writer and astrophysics Shmuel Bialy said by email on Tuesday.

However, he noted that this is only possible for "heavenly bodies" that have a large surface area and are very thin that do not exist in nature. "And that is why I could get another explanation: Ovoramua has been a probe.

Scientists had rejected this theory shortly after finding the object. There were no artificial signals found in the body.

"Like most scientists, I want to be undeniable evidence of terrestrial life, but it is not," said Alan Fitzsimmons, astrophysics at Queens University in Belfast.

"It has already been shown that their observed properties are consistent with a body like the one that has been removed from the second star system," he told AFP. "And some of the arguments put forward in this study are based on figures that have great uncertainties."

Katie Mack, an astrophysicist at North Carolina State University, does not agree with the terrestrial approach.

"You have to understand that scientists are happy to release an extreme idea if they have the slightest chance of being wrong," he wrote on Twitter.

"But until all the other possibilities have been met tenfold, even probably even the writers will create it"he added.

When asked about that, he believes the proposed hypothesis, Bialy told AFP: "I do not say" I believe "that foreigners sent it because I'm a scientist and a believer, and I am confident to present evidence of a possible physical explanation for phenomena discovered."

Another author, Avi Loeb, director of the Harvard Department of Astronomy, told NBC that mankind might not know more about a mysterious object because it has already moved away from the globe and does not return. "It is impossible to guess the purpose behind Oumuamua without any further information."
