BRIAN Cox has claimed aliens have not made contact with us because the most advanced civilizations kill themselves off – and we will too.
The star of TV’s Wonders of the Universe believes eventually every civilization kills themselves off, which is why no beings are yet to make a dominant impact on the universe.
Professor Cox was basing his argument around the Fermi Paradox which questions why humans are yet to make contact with aliens.
In 1950, physicist Enrico Fermi – the creator of the world’s first nuclear reactor – came up with a paradox which says due to the age and size of the universe there is bound to be a civilization much more advanced than ours, but why haven’t they contacted us?
The solution, many scientists argue, is once a civilization reaches a certain size, it eventually kills itself off, either through war with advanced weapons or natural disaster.
