Will Antimatter Engines Power the First Starships? (Video)

Reaching even the closest star to the sun would take tens of thousands of years using conventional propulsion — but an antimatter engine could cut that trip down to just 40 years, according to the company Positron Dynamics. In a new video by Speculative Films, scientists talk about the challenges of visiting Earth's neighboring star system, Alpha Centauri, and the way antimatter could power such a journey. "We're working on a propulsion system based on antimatter that should be able to get
