Famed scientist Stephen Hawking and Russian billionaire Yuri Milner is teaming up on a $100 million project that will send an army of nano-spacecrafts to explore the universe, and hopefully, find aliens.
The Breakthrough Initiative aims to build prototypes of light-propelled nanocrafts that could travel at 20 percent the speed of light, which would enable it to travel 25 trillion miles to Alpha Centauri, the closest star-system from the solar system, in just 20 years.
Some astronomers believe that there could be an Earth-like planet in the “habitable zones” of the three-star system.
