AUDIE CORNISH, HOST: We talked earlier about how hot it's in the summer. But that's nothing when compared to some really sizzling heat we heard about today.</s>MELISSA BLOCK, HOST: Of all places, it happened in Switzerland at CERN in the large Hadron collider, for a tiny fraction of a second. So how hot was it?</s>PAOLO GIUBELLINO: It was something more than five trillion degrees.</s>AUDIE CORNISH, HOST: That's Paolo Giubellino, a physicist with the project. Yesterday, CERN scientists said it is the hottest man-made temperature ever received.</s>PAOLO GIUBELLINO: You can imagine that that may be more than 100,000 times hotter than at the center of the sun.</s>MELISSA BLOCK, HOST: Actually no, I can't imagine it.</s>AUDIE CORNISH, HOST: And I'm not even going to try.</s>AUDIE CORNISH, HOST: And you're listening to ALL THINGS CONSIDERED from NPR News.
In light of this summer's record high temperatures, we find perspective on really hot temperatures. In an experiment, scientists at Europe's CERN laboratory claim to have achieved the highest temperature ever produced by humans — about 5.5 trillion degrees. Audie Cornish and Melissa Block have more.
