- 9 years ago
Professor Stephen Hawking and Russian entrepreneur Yuri Milner have launched a project to search for alien life. The initiative is the largest ever of its kind, and will spend 10 years searching for signals from millions of stars.
Time and space
Why haven’t we found alien life yet? The reasons boil down to space and time. Firstly, the universe is very big and expanding rapidly, so there’s a limit on how far we can see, and secondly it has only been a metaphorical microsecond in the history of the universe that we have been searching for aliens, meaning our chances of finding another civilisation on another planet are very slim.
So today’s news that some of the brightest minds and fattest wallets in physics are going to spend 92 million euros searching for aliens through the Breakthrough Listen project is great for astronomy, and the SETI (Search for Extra-Terrestrial Intelligence) community in particular. They are going to scan the nearest million stars in our own galaxy and stars
