Harvard astrophysicist Avi Loeb has drawn criticism for suggesting ‘Oumuamua, a bizarre object passing via the photo voltaic system could possibly be an alien spacecraft. However he insists we should hold an open thoughts when nature throws us a curveball like this, and that the seek for extraterrestrial life is simply good science.
It’s definitely bizarre. Observations advised ‘Oumuamua is more likely to be both flat or cigar-shaped, tumbling finish over finish each 7 hours or so and accelerating at a tempo seemingly larger than could possibly be accounted for by gravitational forces alone. Loeb’s colleagues have since give you varied pure explanations for what we glimpsed of ‘Oumuamua’s options, together with the concept it’s some type of giant fractal snowflake. However he’s adamant we should always a minimum of be open to the chance that it could possibly be proof of the existence of extraterrestrial civilisations.
