Being able to identify when something is hot was likely one of the first skills you were taught as a child. But have you ever wondered what's the hottest thing EVER? While "ever" is certainly hard to define, scientists have determined that the hottest thing in recorded history was an experiment from the Large Hadron Collider (LHC) in 2012. To learn what particles are made of and how they interact, the LHC accelerates ions or protons close to the speed of light before smashing them into each other. These collisions normally create explosions, but this one was a lot bigger than usual. In the following video, discover ALICE and its mission to learn about a pre-historic substance called quark-gluon plasma. (Spoiler: It involves a 5.5 trillion degrees Celsius fireball.)
