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.
But when matter and antimatter come into contact, they annihilate – disappearing in a flash of energy. 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.
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.

Sep 27, 2023 · Antimatter is the opposite of matter, from which stars and planets are made. Both were created in equal amounts in the Big Bang which formed our Universe. While matter is everywhere, though, its...

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...
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.
