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.
So why is there far more matter than antimatter in the universe? 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.
