Proposed Experiment to Convert Light into Matter in Simplest Way Known

Light to Matter Conversion: Given enough energy, two colliding photons (light particles) can produce a matter particle and antiparticle, such as the electron and positron shown here.

Experiments have shown how to convert matter into light, but reversing the process isn’t quite as simple. There’s a new theory to solve the puzzle.
