Antimatter? Huh? This isn't science fiction - scientists at the European CERN laboratory caught particles of antimatter with magnets, man, and we'll tell you how they work. Sean Carroll, a theoretical physicist at CalTech, joins us to talk shop and get you jazzed about what this discovery means for our understanding of life, the Big Bang, and the Universe as it exists today.

The Geneva-based CERN particle physics laboratory confined antimatter particles in a magnetic trap. Though predicted to exist in 1931 by Carl Anderson and observed in 2002, antimatter particles have not been able to be observed for more than a few milliseconds due to their volatile interaction with any kind of matter, requiring an immobilization like CERN's innovative use of magnetic fields.
