supernovae, which can reach temperatures exceeding 100-billion degrees.

The universe may be fairly cold today, yet things were not always this way. During the first moment of the Big Bang, temperatures likely reached a staggering 180-million trillion trillion degrees Fahrenheit. Within the first 100-seconds of time, temperatures cooled to around 180-billion degrees Fahrenheit.
