World-first light propulsion ‘metajets’ could enable 20-year mission to Alpha Centauri
SMRTR summary
Scientists at Texas A&M University have developed "metajets" — tiny light-propelled devices that can move in three dimensions using laser beams alone, a world first. This breakthrough could eventually enable a spacecraft to reach Alpha Centauri in just 20 years, offering a more scalable alternative to traditional light propulsion.
