what is the hottest temperature in the universe
Absolute hot Contemporary models of physical cosmology postulate that the highest possible temperature is the Planck temperature, which has the value 7032141678500000000♠1.416785(71)×1032 kelvins, or 142 nonillion kelvins (142 quintillion on the long scale).[3] Above about 1032K, particle energies become so large that gravitational forces between them would become as strong as other fundamental forces according to current theories. There is no existing scientific theory for the behavior of matter at these energies. A quantum theory of gravity would be required.[4] The models of the origin of the universe based on the Big Bang theory assume that the universe passed through this temperature about 10−42 seconds after the Big Bang as a result of enormous entropy expansion.[3]
