Understanding the Hottest Things in the Universe

The video explores the hottest phenomena in the universe, starting with the Large Hadron Collider's 2012 experiment that created quark-gluon plasma at 5.5 trillion degrees Celsius. It then discusses the intracluster medium in galaxy clusters, heated by black holes, and the universe's temperature right after the Big Bang, which might have reached absolute hot. The video concludes with a call to support SciShow on Patreon.
