	The '''quantum matter–antimatter asymmetry problem''', also called the '''baryon asymmetry problem''', is the open problem of explaining why the observable universe contains far more matter than antimatter. In the early universe, known physics suggests that matter and antimatter should have been produced in nearly equal amounts. If this had happened exactly, most particles and antiparticles would have annihilated into radiation, leaving little ordinary matter from which galaxies, stars, planets, and life could form.
