What appears to be a new form of matter, known as color-glass condensate, was formed in the Large Hadron Collider through collisions between lead ions and protons. Scientists observed that though new particles from the collisions fly off in all directions at nearly light speed, some fly in correlated directions. "Somehow they fly at the same direction even though it's not clear how they can communicate their direction with one another. That has surprised many people, including us," said Gunther Roland, a physics professor at the Massachusetts Institute of Technology.
