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 …

Dec 13, 2021 · Antimatter is the same as ordinary matter except that it has the opposite electric charge. For instance, an electron, which has a negative charge, has an antimatter partner …

Aug 30, 2020 · Learn what antimatter is, how it differs from regular matter, and what happens when the two collide. Get examples of antimatter in real life.

Jan 22, 2025 · Antimatter is, in a short phrase, the opposite of matter. If you think of everything that is around you—chairs, tables, or even air—that is all regular matter. But for every variety …

Sep 11, 2025 · Antimatter, substance composed of subatomic particles that have the mass, electric charge, and magnetic moment of the electrons, protons, and neutrons of ordinary …

Oct 25, 2021 · Every physics process we know of creates equal amounts of matter and antimatter. When a particle meets its antiparticle however, it ‘annihilates’, ultimately into high …

Sep 22, 2025 · Although antimatter doesn’t seem to be very common in the Universe today, it is frequently created at laboratories like CERN, where particle accelerators simulate the high …

Nov 24, 2023 · Antimatter, the mirror image of matter’s subatomic particles, is a fascinating yet elusive element of our universe. Although theories suggest equal amounts of matter and …

Antimatter refers to all particles that share the same mass as their counterparts but have opposite properties, such as electric charge. These are called antiparticles.

At CERN, physicists make antimatter to study in experiments. The starting point is the Antiproton Decelerator, which slows down antiprotons so that physicists can investigate their properties.
