Lasers are awesome. The laser was once the stuff of fiction and today we use lasers for all sorts of cool things. We can burn things with them, the military is using them for weapons, and some researchers are using the laser to transfer data much faster than wires can. The world record for shooting data down a path with lasers is 101.7 terabits per second. That record setting system used a whopping 370 separate lasers making it expensive and impractical with today's laser tech.
