There may be a strange reason why we haven’t been able to track down aliens despite the vast size of the universe.
A theoretical physicist believes its because ‘alien killer robots may have destroyed every extraterrestrial civilisation’ in the cosmos.
Alexander Berezin of the National Research University of Electronic Technology in Russia came up with bizarre theory to explain something known as the ‘Fermi paradox’.
This paradox describes the contradiction between the likelihood that alien life is present somewhere in the vastness of the universe, and the lack of any evidence to prove its existence.
The Fermi Paradox, named after physicist Enrico Fermi, has perplexed scientists for decades.
But Professor Berezin suggests it occurs because advanced civilizations will destroy other lifeforms with their technology.
He believes any civilisations of ‘biological organisms like ourselves or rogue AIs that rebelled against their creators’ which tries to colonise other planets will inevitably destroy every species in its way.
Berezin has published a paper, which has yet to be peer-reviewed, which describes his so-called ‘first in, last out’ solution to the Fermi Paradox.
He writes: ‘I am not suggesting that a highly developed civilization would consciously wipe out other lifeforms.
‘Most likely, they simply won’t notice, the same way a construction crew demolishes an anthill to build real estate because they lack incentive to protect it.’
If humanity achieves interstellar travel and begins colonising any of the estimated 100 billion planets in our galaxy alone, it will eradicate ‘all competition to fuel its own expansion’.
But if humanity doesn’t achieve this advanced level of space travel, it is doomed to be eradicated by aliens or extraterrestrial AI-powered computers as they expand their civilisation.
