Physicists theorize dark matter could actually be created in the most powerful particle collider in the world – the 27 kilometer-long Large Hadron Collider (LHC), in Geneva, Switzerland. So, how would they do it?

In LHC, two proton beams travel in opposite directions at nearly the speed of light. At four collision points, the beams cross and protons smash into each other. As you already know, protons consist of much smaller components called quarks and gluons. In most ordinary collisions, these components in protons pass through each other without any significant outcome. However, in about one in a million collisions, these two components hit each other so violently, that most of the collision energy is set free producing thousands of new particles – including very massive particles, like the theorized dark matter.
