And that could bring physicists one step closer to understanding how everything in the universe came to be.For the most part, particles and their oppositely charged antiparticles are like perfect mirror images of one another. But some particles disobey this symmetry, a phenomenon known ascharge-parity, or CP, violation. Now, researchers at the Large Hadron Collider near Geneva have spotted CP violation in a class of particles called baryons, where its never been confirmed before.Sign up for our newsletterWe summarize the week's science breakthroughs every Thursday.
