The alleged asteroid Oumuamua has long been a subject of intense debate in scientific circles for a year, where both aliens and traditional theories show no signs of stopping.
What was perceived as an interstellar asteroid, later referred to as Oumuamua, appeared for the first time in October 201
The Harvard astronomer Avi Loeb made headlines at the time, because he was particularly fond of the first known interstellar object to visit Our Solar System and still stands to his conclusions.
"For me, the question of being alone is the most basic in science," said Avi Loeb, chairman of the Department of Astronomy at the US University. He argues that, from a scientific point of view, it is essential to do at least one Oumuamua alien examination. In an interview, he told The Express that people are really angry at the general prejudice against alien civilizations.
"There's all this baggage from science fiction and UFO objects," he said. He added that the scientific community "is shying away from the discussion about the search" for what it means by its high-ranking position and reputation on the prestigious US university supports.
required extraordinary evidence, "he said, further arguing that he" would motivate them to collect more. "
According to Loeb, Oumuamua could be a light, if it's like a pancake or awning, sails, powered by Sunlight, much like the wind pushing a boat, is currently being developed and tested by NASA and other research groups, such as Breakthrough Starshot, to which Loeb belongs.
"It is quite possible that another civilization, the had much more time for their technological development, this already matured technology, and as a result they use it, "he said, adding that it was not speculation, but scientific assumptions based on Oumuamua's unusual trajectory and inexplicable speed increases.
"You can imagine many other civilizations out there A quarter of all stars has a planet of the size and approximate surface temperature of the earth. And these planets could hold liquid water and with it the chemistry of life as we know it, "the astronomer said before continuing:
" So if you roll billions of cubes in the Milky Way alone, it is very likely that we are not alone, "he claimed, reiterating that Oumuamua does not look like any asteroid or comet ever seen in this solar system, as it deviates from the traditional orbit and has no typical comet tail or gas around it.  It was, of course, no surprise that the view met with criticism. One astrophysicist has tweeted that the authors insult "honest research to even suggest it," while another, Julie Ziffer, who heads the physics department at the University of Southern Maine, says she does not consider that a "probable scenario." agree with many others that Oumuamua is of natural origin.
"I think it was ejected from another system and is probably a fragment of a rocky body," said Digit. She cited three reasons that she does not believe Oumuamua is an extraterrestrial object: the lack of a detected radio signal, second, the fact that it crashes rather than being controlled.
And last but not least, Digit said it would have been sent out millions of years ago and would have obviously left the solar system, never to return. According to Amaya Moro-Martin of the Space Telescope Science Institute in Baltimore, quoted by New Scientist, Oumuamua appeared naturally and could be a fractal snowflake.
