In Ron Howard's Angels & Demons Tom Hanks plays Harvard academic Robert Langdon, who discovers evidence of the resurgence of an ancient secret brotherhood called the Illuminati - the most powerful underground organization in history.
When Langdon finds evidence that the Illuminati have stolen antimatter from a secret laboratory at CERN, which they plan to use as a devastating weapon to destroy the Vatican, he and CERN scientist Vittoria Vetra begin a race against time to recover the antimatter and prevent catastrophe.
But what is antimatter? Is is real? Is it dangerous? What is CERN?
Large-scale annihilation of antimatter and matter could theoretically be used in a destructive way - but could it be used to make a bomb?
Matter's secret twin? This sounds like science fiction - is it?
CERN is the European Organization for Nuclear Research - what's with the two names?
