In 2o18, Harvard's Avi Loeb suggested that 'Oumuamua was an alien spacecraft.
It was first thought to be a comet. However, 'Oumuamua “is cigar-shaped, measuring about 200 metres in length (650 feet) and 34 metres wide (114 feet), and rotates once every seven hours. It was also found to be accelerating instead of slowing down—a discovery that was difficult to explain.”
Now, “a study published in Nature Astronomy, an international team of researchers has concluded 'Oumuamua has a ‘purely natural origin,’ and that a host of natural phenomena can explain it.”
Sometimes, scientists view of the universe might be wrong. More and more space signals have turn to be false.
Almost all signals caused by interstellar signals have been false.
