<P> Contemporary models of physical cosmology postulate that the highest possible temperature is the Planck temperature , which has the value 7032141678500000000 ♠ 1.416 785 ( 71 ) × 10 kelvins , or 142 nonillion kelvins ( 142 quintillion on the long scale ) . Above about 10 K , 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 . The models of the origin of the universe based on the Big Bang theory assume that the universe passed through this temperature about 10 seconds after the Big Bang as a result of enormous entropy expansion . </P>
