Avi Loeb, the chair of Harvard’s astronomy department continues to maintain that the mysterious Oumuamua asteroid is , in fact,an alien object. He is convinced that aliens exist, and he has plenty of arguments to back up his theory.
By analyzing the objects, he discovered many suspicions things. For example, its speed cannot be explained. While the Oumuamua travels at 196,000 mph it also accelerates in ways that cannot be explained.
Loeb also explained while the existence of aliens is plausible. “I do not view the possibility of a technological civilization as speculative, for two reasons,” he declared. “The first is that we exist. And the second is that at least a quarter of the stars in the Milky Way galaxy have a planet like Earth, with surface conditions that are very similar to Earth, and the chemistry of life as we know it could develop.”
However, not everyone is convinced that the Oumuamua has alien origins. In fact, multiple people from the scientific community are against Loeb’s theory. There are many other plausible explanations as well, and some of them were offered by NASA scientists for instance.
“This model of ‘Oumuamua provides an opportunity to consistently explain its nongravitational acceleration as an effect of solar radiation pressure. The rest of the parent dwarf comet’s debris is expected to have escaped detection,” explained longtime NASA scientist Zdenek Sekanina.
Nonetheless, Loeb managed to reject Sekanina’s theory. According to Loeb, “in order for radiation pressure from sunlight to provide the observed push on Oumumua, the thickness of the object needs to be less than a millimeter”. In a natural debris cloud, this is almost impossible to achieve. On the other hand Sekanina continues to believe that his model adds up. In the end, we can only speculate.
