Is it true that Oumuamua is a foreign plane?


There is a new suspicion that Umu Oumuamua crosses our solar system in 2017. The object, previously considered as an asteroid, is now considered as a foreign spacecraft sent to explore the Earth.

This assumption is based on the latest research results from two Harvard astronomers, Abraham Loeb and Shmuel Bialy. The results of their research have been published in the Astrophysical Journal Letters.

Oumuamua is enough to make experts stun. It was originally named a comet, then an asteroid, and eventually gave a new name, an interstellar object interstitial object.

In fact, "What is Oumuamua an object? Is it really a foreign plane?

Previously there was a study that attempted to study whether there was a signal that could enter or exit Oumuamua using the Murchison Widefield Array (MWA) radio telescope in Australia. And the results of the study, the results of which were also presented in the journal Astrophysical Journal Letters, did not find any signs of entry or exit of umu Oumuamua.

"We do not find signals coming from Earth," the researchers write in the results of the survey.

Live Science (ICRAR) surveyed data collected by the MWA in November 2017, December 2017, and early January 2018, when Oumuamua is at a distance of 95 to 366 million kilometers from Earth.

They control broadcasts at frequencies between 72 and 102 megahertz or frequencies similar to those used by the FM radio.

Although the research team did not receive any transmission that might have come from an extraterrestrial culture, they said, this research was an important step towards finding other cultures outside the Earth.

"If there is an extraterrestrial civilization in a corner of our galaxy, we can think that they could have developed the ability to launch spacecraft capable of traveling between stars and aircraft that could use radio waves to communicate," said researcher Steven Tingay.

Meanwhile, in relation to Harvard's latest investigations, there are some researchers who see it skeptical.

"It is very important that we do not use large institutions to overestimate unverified or extravagant finds," said Chanda Prescod-Weinstein, assistant professor of physics at New Hampshire University, Gizmodo.

"Because it affects not only the reputation of your department but also your entire field," he added.

In addition, Coryn Bailer-Jones, an astronomer at Max Planck's Institute of Astronomy in Germany, has also expressed similarities.

"We have to ask ourselves:" Where is the proof? "Instead of saying" Where there is less evidence, so I can get into the case I like? "Said Bailer-Jones from NBC.

There are also SETI Institute astronomers who say that we should not accept a strange assumption when there is another reason that is more reasonable and unambiguous as the object is a comet or asteroid.

In addition, there is an astronomer from the Harvard-Smithsonian Center for Astrophysics, the same institution with two researchers who published this latest research, which also states that the probability of "Oumuamua as foreign spacecraft is too small.

However, there is also Katie Mack, a professor of astrophysics at North Carolina State University, who says that calculating the possibilities for research is not wrong.

"But as readers, we have to realize that just because a proposal gets the press attention or comes from a specialist does not mean we have to consider it the end result," Mack said Gizmodo.

Loeb himself said the results of the research he and his colleagues were doing was uncertain, but the results were quite interesting.

"I can accept other views, but I can not think of another explanation for the abnormal acceleration of" Oumuamua, "he added.
