It is expected that equal amounts of matter and antimatter were created at the birth of the Universe. However, very little antimatter can be found today. In an endeavour to find whether hydrogen and antihydrogen have the same properties, the ALPHA collaboration, based at CERN, creates, holds and tests antihydrogen for precision comparisons of the two simplest antimatter and matter elements. Charge, parity and time invariance, which is central to the theory which leads us to conclude that once upon a time there was a matter/antimatter balance, demands that there is no difference between the two. Hydrogen has been extensively studied both theoretically and experimentally to a great precision. The collaboration has recently developed tools which makes it uniquely placed to attempt reaching an understanding with a similar precision in antihydrogen.
Established in 1920, Swansea University is a non-profit public higher education institution located in the suburban setting of the large town of Swansea (population range of 50,000-249,999 inhabitants), Wales.
