There is a chance that 'Oumuamua, a mysterious object that visited our solar system back in 2017, was an alien spaceship that came by for a visit.
It has been argued that 'Oumuamua could have been a probe sent by an extraterrestrial civilization, an explanation that has divided his peers.
An international team of researchers tried to undermine the idea that 'Oumuamua was a solar sail, an advanced form of propulsion that would allow a spaceship to use the low pressure of solar radiation.
The team concluded that 'Oumuamua is not likely to be a light sail. The dynamics of a light sail can be analyzed using our methods.
The man is sticking to his guns.
He told The Daily Beast that there are a few points that the authors have missed.
The international team argued that if 'Oumuamua was a light sail, it would have a large flat surface that reflected more light than what we saw.
The brightness variation should be larger if it was a light sail.
The sail needs not be flat. It could've been a light sail that reflected light in unexpected ways according to his research.
The astronomer said that 'Oumuamua may not be a sail at all, but just a surface layer torn apart from a bigger object.'
There are extraordinary measures that need to be taken. Maybe the object was a comet that exploded in the air.
It is extremely rare to see an object like 'Oumuamua.
With help of a huge amount of highly accurate observation data in the future, maybe we could finally put the mystery to rest.
