普朗克溫度

The Planck temperature, named after German physicist Max Planck, is the natural unit of temperature, denoted by Tp. It is calculated by the following equations,

Tp = square-root[(h/2.pi).c^5/Gk^2]
where h is Planck's constant
c is the speed of light
G is the Universal Gravitational Constant
k is Boltzmann constant
pi = 3.14159....

Tp has the value of 1.42 x 10^32 K

The Planck temperature is assumed to be the highest temperature in conventional physics because conventional physics theories break down at that temperature. Therefore, talking about anything being "hotter" than the Planck temperature doesn't make a lot of sense.

Above the Planck temperature of ~1032K, it is postulated that particle energies become so large that the gravitational forces between them become as strong as any other force. It is also believed that the Planck temperature is the temperature that occured at the "Big Bang" when he Universe started to cool down. It is thus difficult to imagine anything hotter than the Big Bang.

do you know how much is the Planck's temperature??
