Russian Internet investor Yuri Milner is funding a $100 million project to search for life beyond Earth. The project, Breakthrough Listen, is the biggest effort of its kind. The search for extraterrestrial life, often referred to as SETI, started in 1960 and has yet to find any evidence of alien life. Milner didn’t say if he thought the scientists would actually find extraterrestrial life, but he did say that he hopes we are not alone.
