Is it true that Oumuamua is an alien plane?

There is a new suspicion of umu Oumuamua that crosses our solar system in 2017. The object, considered previously as an asteroid, is now thought to be an alien spaceship sent to investigate the Earth.

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

"Oumuamua itself is enough to confuse the experts. Initially a comet was called, soon an asteroid, and finally gave a new designation, an interstellar or an object interstellar object.

In fact: "What is Oumuamua an object? Is it really an alien plane?

Previously there was a study that tried to study if there was a signal that could enter or exit from "Oumuamua & # 39; using the Murchison Widefield Array (MWA) radio scape in Australia. And the results of the study, whose results were also presented in the journal Astrophysical Journal Letters, have not found any sign of entry or exit of umu Oumuamua.

"We do not find any sign that has origins not from the Earth," the researchers wrote in the results of the investigation.

Live science reported that the research teams of the International Radio Astronomy Research Center (ICRAR) studied data captured by MWA in November 2017, December 2017 and early January 2018, when "Oumuamua is within a range of 95 million to 366 millions of miles from Earth.

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

Although the research team did not catch any transmission that might have come from an alien civilization, they said that this investigation was an important step in finding other civilizations outside the Earth.

"If there is an alien civilization in a corner of our galaxy, we can speculate that they may have developed the ability to launch spacecraft capable of traveling between stars and airplanes that can use radio waves to communicate," said research leader Steven Tingay.

Meanwhile, related to the most recent research by Harvard researchers, there are some researchers who see it skeptically.

"It is very important not to use large-name institutions to overestimate unverified or highly speculative results," said Chanda Prescod-Weinstein, a physics assistant professor at the University of New Hampshire, to Gizmodo

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

In addition, Coryn Bailer-Jones, an astronomer at the Max Planck Institute of Astronomy in Germany, also expressed similar things.

"We have to ask ourselves:" Where are you trying? "Instead of saying" Where there is less evidence, then I can go into the hypothesis that I like, "said Said Bailer-Jones quoted from NBC.

There are also astronomers from the SETI Institute who say they should not accept a strange hypothesis when there is another more plausible and indisputable hypothesis, since the object is a comet or an asteroid.

In addition, there is an astronomer at the Harvard-Smithsonian Center for Astrophysics, the same institution with two researchers who issued this latest investigation, which also states that the possibility that "Oumuamua is a foreign spacecraft is very small."

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

"But as readers, we must realize that just because a proposal receives the attention of the press or comes from an expert does not mean that we have to consider the final result," said Mack Gizmodo

Loeb himself said that the results of the research he and his colleagues did for this were uncertain but the results were quite interesting.

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