Remember CERN? Sure you do! They were the folks with the Large Hadron Collider who discovered that Higgs boson thing back in July. Well, they’re at it again with all their science and their 17-mile-long particle accelerator, and they’ve even broken a world record. CERN’s physicists have created the highest human-made temperature in history with their ALICE heavy ion collider, beating the previous record of four trillion Kelvin. ALICE produced a quark-gluon plasma, a sort of subatomic milkshake if you replace the milk with quarks, the ice cream with gluons, the blender with a large ion collider, and the cherry on top with ground-breaking scientific discovery. This is starting to sound less and less like a milkshake. Read on for the full scoop.
