According to superstrign theory there is a maximum temperture at which point time itslef would break down just as the molecules do in an ice cube to become water. It is reckoned that at about 1 million million million million milllion million million million degrees celcius (a temperture hotter than the big bang), the universe would burn and a hole would be made in space-time.
If zero degrees Kelvin is the coldest temperature, is there a maximun?
