Scientists just fired the most powerful laser in the world, at the Lawrence Livermore National Laboratory's National Ignition Facility. It's a 10 story laser. It is the most powerful laser ever recorded.
On July 5th, the scientists fired the 192 constituent laser beams simultaneously, before focussing them down onto a circular target just 2 millimeters in diameter. The laser beam transmitted 500 trillion watts. Is this the beginning of the Death Star, we wonder?
