Experiments have started at a new 'antimatter factory' at CERN in Geneva. The laboratory's Antimatter Decelerator (AD) is delivering low-energy antiprotons to three experiments that will probe the difference between matter and antimatter. The experiments could shed light on why our universe appears to contain only matter, even though it is thought that equal amounts of matter and antimatter were created in the Big Bang.
