This is such a cool idea. “To propel the bots into hyper drive will require energy from a ground-based laser, which would blast a beam of light at the tiny bots’ sails for two minutes, accelerating the bot to one-fifth the speed of light, roughly 100 million miles per hour. At that rate, the swarm of light-propelled probes could reach Alpha Centauri, 4.37 light years away, in about 20 years.”
