Physicists Detect Strongest Evidence Yet of Matter Generated by Collisions of Light

Now, physicists at Brookhaven National Laboratory say they've found a way around this stumbling block using the facility's Relativistic Heavy Ion Collider (RHIC) - resulting in a direct observation of the Breit-Wheeler process in action.

"In their paper, Breit and Wheeler already realized this is almost impossible to do," said physicist Zhangbu Xu of Brookhaven Lab.
