Sep 7, 2016 · 1. The Large Hadron Collider is colder than outer space. To be precise, it’s 1.9 K (-271.3°C), almost absolute zero. A cryogenic cooling system keeps it this frigid for the sake of the superconductor electromagnets, which send proton beams hurtling towards one another in a loop 100 metres below the ground. You too would need help keeping ...
