In modern physics, antimatter is defined as matter composed of the antiparticles (or "partners") of the corresponding particles in "ordinary" matter, and can be thought of as matter with reversed charge, parity, and time, known as CPT reversal.
The Big Bang should have created equal amounts of matter and antimatter. So why is there far more matter than antimatter in the universe? At CERN, physicists make antimatter to study in experiments.
25 de mai. de 2024 · antimatter, substance composed of subatomic particles that have the mass, electric charge, and magnetic moment of the electrons, protons, and neutrons of ordinary matter but for which the electric charge and magnetic moment are opposite in sign.
27 de set. de 2023 · Scientists have made a key discovery about antimatter - a mysterious substance which was plentiful when the Universe began. Antimatter is the opposite of matter, from which stars and planets are...
27 de set. de 2023 · For the last 20 years, scientists from the ALPHA group have been collecting antimatter at CERN, siphoning high-energy antiprotons from collisions in the CERN Proton Synchrotron and slowing them...
Antimatter is the opposite of matter in every respect, except for its charge. Learn how antimatter is produced, annihilated and studied, and why the universe is mostly made of matter.
Antimatter detectives. The antimatter is missing – not from CERN, but from the Universe! At least that is what we can deduce so far from careful examination of the evidence. For each basic particle of matter, there exists an antiparticle with the same mass, but the opposite electric charge.
