Antimatter By Franklin Talbert • Antimatter is matter with the opposite charge as normally observed • It was first theorized to exist in 1928 by Paul Dirac and first observed in 1932 • When antimatter comes into contact with matter they annihilate each other • This poses serious challenges to the study of antimatter but also means it could one day be used as fuel • This property of antimatter is also used in PET scans or Positron Emission Topography • The ALPHA experiment at CERN managed to trap anti-hydrogen for 1000 seconds in 2011 • This and other advances will allow for more careful study of antimatter in the future
