The trouble is, there's one MAJOR problem nobody is talking about.A Russian billionaire has vowed to spend a huge chunk of his fortune on funding the search for alien life.
Investor Yuri Milner appeared alongside Professor Hawking at London's Royal Society today to announce the beginning of the "biggest ever" attempt to locate extraterrestrial civilisations.
The one million stars closest to Earth will be examined in unprecedented detail and telescopes will peer deep into the centre of the Milky Way. He will fund the rejuvenated quest to find life on other planets through his Breakthrough Initiatives project, which will hand over $100 million (£64 million)
This pioneering quest will cover a 10 times larger patch of space than any other search, whilst zeroing in on areas of interest with a resolution 50 times greater than anything achieved before.
The one thing that would cause us serious issues.
How do we communicate with species that have no idea about human communication?
