物理学家试图把光变成物质

根据爱因斯坦质能方程 E=mc2，反推就是m=E/c2

Eight-four years ago, scientists Gregory Breit and John Wheeler theorized that it would be possible to turn light into matter. However, it was long thought that proving this would be beyond the capabilities of scientists.

Now physicists from Imperial College London (ICL) in the U.K. are attempting to prove the impossible in a potentially groundbreaking experiment.

The theory, known as the Breit-Wheeler process, states that smashing together two particles of light, or photons, would create matter in the form of a negatively charged electron and its antiparticle, a positron. Both electrons and positrons have a small mass unlike photons, which have no mass.
