Antimatter sounds like the stuff of science fiction, but in fact it is real and a major tool in medicine, technology and science. This talk introduces antimatter and one of the biggest mysteries in cosmology: why is there no antimatter in the universe at large? Experiments about to begin in California hope to find clues to the answer.
