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.
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.
May 25, 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.

Dec 13, 2021 · All about antimatter, where it is produced and how to power a spacecraft with it
Aug 30, 2020 · Antimatter is matter composed of antiparticles with the opposite electrical charge of ordinary particles and different quantum numbers. A regular atom has a nucleus of positively-charged protons and neutrons that is surrounded by a cloud of negatively-charged electrons.
Sep 27, 2023 · Scientists have made a key discovery about antimatter - a mysterious substance which was plentiful when the Universe began.
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.
The world we live in is overwhelmingly made up of particles of matter. But many of these particles have an antimatter equivalent: a particle identical in every respect, but with an opposite...
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 should exist, the observable universe predominantly contains matter.
Why isn’t antimatter everywhere? When matter and antimatter meet, they annihilate each other, releasing energy. That leads us to the biggest mystery about antimatter. Scientific theories predict that the Big Bang should have created the same amount of matter and antimatter.
