15. Feelin’ Hot Hot Hot
The Large Hadron Collider, built by the European Organization for Nuclear Research (CERN) is believed to be the largest machine in the world and a powerful particle collider. The LHC could create temperatures to an unbelievably hot 9.9 trillion degrees Fahrenheit — or 5.5 trillion degrees Celsius. The sun seems much cooler compared to this with temperatures reaching 27 million degrees Fahrenheit (15 million Celsius) at its hottest.
