Physicists Investigate Phase Diagram of Nuclear Matter

Nuclear matter is a hypothetic substance consisting of interacting quarks and gluons in large enough numbers that the system can be considered infinite. Left:...

Two gold ions (red) move in opposite direction at 99.995% of the speed of light (v, for velocity, = approximately c, the speed of light). As the ions pass one another without colliding, two photons (γ) from the electromagnetic cloud surrounding the ions can interact with each other to create a matter-antimatter pair: an electron (e-) and positron (e+).
