Stephen Hawking to Unveil New Space Exploration Project Tuesday

Stephen Hawking will announce a mysterious new space exploration initiative Tuesday, and there's plenty of reason to think it will be a pretty big deal. There's the famed astrophysicist's involvement, for starters, as well as the project's name — "Starshot." Furthermore, Hawking will make the announcement with billionaire entrepreneur and investor Yuri Milner, who is also bankrolling a 10-year, $100 million search for extraterrestrial intelligence (SETI) initiative called Breakthrough List
