<figcaption>Paul Dirac (Image: <a href="https://commons.wikimedia.org/wiki/File:P.A.M._Dirac_at_the_blackboard.jpg">Wikimedia</a>)</figcaption> </figure> <p>In 1928, British physicist Paul Dirac wrote down an equation that combined quantum theory and special relativity to describe the behaviour of an electron moving at a relativistic speed. The equation – which won Dirac the <a href="http://www.nobelprize.org/nobel_prizes/physics/laureates/1933/">Nobel Prize in 1933</a> – posed a problem: just as the equation x<sup>2</sup> = 4 can have two possible solutions (x = 2 or x = −2), so Dirac's equation could have two solutions, one for an electron with positive energy, and one for an electron with negative energy. But classical physics (and common sense) dictated that the energy of a particle must always be a positive number.</p> <p>Dirac interpreted the equation to mean that for every particle there exists a corresponding antiparticle, exactly matching the particle but with opposite charge. For example, for the electron there should be an "antielectron", or "positron", identical in every way but with a positive electric charge. The insight opened the possibility of entire galaxies and universes made of antimatter.</p> <p>But when matter and antimatter come into contact, they annihilate – disappearing in a flash of energy. The <a href="/about/physics/early-universe">Big Bang</a> should have created equal amounts of matter and antimatter. So why is there far more matter than antimatter in the universe?</p> <p>At CERN, physicists make antimatter to study in experiments. The starting point is the <a href="/science/accelerators/antiproton-decelerator">Antiproton Decelerator</a>, which slows down antiprotons so that physicists can investigate their properties.</p>
