Absolute Hot

This essay by Peter Tyson on Nova posits an interesting question: If there is is an absolute coldest possible temperature (0 Kelvin) is there an opposite, a hottest possible temperature? He asked a bunch of physicists and got a bunch of varying responses. One guy thought it might be around the temperature being probed by the Large CERN Collider I wrote about back here. Yikes!

When I was at school in Boulder, Colorado they were doing experiments venturing closer to Absolute Zero. I remember being fascinated by the fact that the coldest know point in the universe was no longer some distant corner of space but instead was now inside one of the buildings I walked past every day.
