Assuming you're talking about the temperature, it's always been a source of human pride to me that the hottest place in the entire universe, as far as we are aware, has been created at the LHC on Earth.

Barring other species as intelligent as ours elsewhere (which is of course possible, but unknown), the very hottest thing in the entire unimaginably-large universe full of exotic stars and black holes and supernovae, was created by a tiny group of apes on a minuscule planet orbiting a smallish, boring star on the unfashionable side of a galaxy.
