![]() ![]() Using an accelerator at Berkeley University, Segre and Chamberlain discover the antiproton. Two major discoveries helped physicists to establish this fundamental principle:Įxamining cosmic-ray data, Anderson discovers the positively charged electron later named the positron. This transition generates a pair of photons, which are bumps on the normally flat electromagnetic field.Įvery matter particle has an antimatter antiparticle. The particles cease to exist, but the field continues on for eternity. No height or depth means no electron or positron. When an electron and an positron meet, the bump falls into the pit and the electron field flattens out. A bump in the electron field is an electron and a pit is a positron. Where there are no electrons, there is no height or depth. As far as the electron field is concerned, empty space is flat. We can also visualize fields as a surface whose height at a location corresponds to its value. The loss of mass excites the electromagnetic field producing two photons that zip away at the speed of light. When an electron and a positron meet, they both cease to exist or annihilate. When a positive number is added to a negative number, the sum is zero. Where there are positrons (antielectrons), the electron field has a negative value. Where there are electrons, the electron field has a positive numerical value. Likewise, the value of the electron field in empty space is zero. When a photon passes by, the electromagnetic field stops being zero wherever the photon is located at that particular instant. The value of the electromagentic field in a region of pure and utter darkness is zero. ![]() A field is any quantity that has a value everywhere in space. ![]() The electromagnetic field is one example. ![]()
