What Are The Hottest And Coldest Things In The Universe?

The video explores the hottest and coldest temperatures recorded in the universe. It begins with Earth's extreme temperatures, such as Death Valley's heat, and compares them to the Sun's surface and core temperatures. The video then discusses supernovas, which reach temperatures far exceeding the Sun's. The hottest temperature was artificially created at CERN, simulating conditions post-Big Bang. Theoretical limits like the Planck temperature, or absolute hot, are also mentioned. On the cold spectrum, the Boomerang Nebula is the coldest natural spot, while a lab in Italy achieved near absolute zero. The video highlights the potential for future scientific advancements to break these temperature barriers.
