Think It's Hot? The Swiss Just Hit 5.5 Trillion Degrees

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.

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.

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?

PAOLO GIUBELLINO: It was something more than five trillion degrees.

CORNISH: That's Paolo Giubellino, a physicist with the project. Yesterday, CERN scientists said it is the hottest man-made temperature ever received.

GIUBELLINO: You can imagine that that may be more than 100,000 times hotter than at the center of the sun.

BLOCK: Actually no, I can't imagine it.

CORNISH: And I'm not even going to try.
