你牛。我Google了才知道
Apparently, the highest possible known temperature is 142 nonillion kelvins
(That is 142 followed by 30 zeroes). This is the highest temperature that
scientists know of according to the standard model of particle physics,
which is the physics that underlies and governs our universe. Beyond this,
physics starts to breakdown. This is known as Planck Temperature. Ultimately
, this can only come about when particles achieve what is known as thermal
equilibrium. In order for it to be the hottest temperature, physicists
assert that the universe would have to reach thermal equilibrium, with a
temperature that is so hot, all the objects in the universe are at the same
temperature.
The closest that scientists think we ever came to this temperature is,
unsurprisingly, just after the Big Bang.
