Browsing: Antimatter
Antimatter is a substance composed of antiparticles, which have the same mass as particles of ordinary matter but opposite charges, as well as other particle properties like spin and magnetic moment. When a particle and its antiparticle meet, they annihilate each other, releasing energy in the form of radiation, typically gamma rays. This annihilation process makes antimatter extremely interesting both theoretically and practically. It has important applications in medical imaging, specifically in positron emission tomography (PET) scans, where a positron (the antiparticle of the electron) is emitted and subsequently annihilates with an electron, helping to produce detailed images of internal bodily structures. Theoretical and experimental studies of antimatter also provide significant insights into the fundamental symmetries of the universe and help test predictions of the Standard Model of particle physics. The production and study of antimatter are challenging due to its tendency to annihilate upon contact with matter, requiring sophisticated techniques to create and trap antimatter particles without them coming into contact with normal matter.
