Why does the universe favor matter over antimatter? Who better to ask than an experimental particle physicist. Image Credit: IFLScience

Everything we see, from galaxies to capybaras, is made of matter. But matter has a mirrored version of itself known as antimatter. If the two come into contact they annihilate one another, turning into pure energy. Why does the universe prefer one over the other? This is a fundamental mystery of the universe, and at the forefront of the search for an answer is the Alpha Experiment at CERN. In this episode, host Dr Alfredo Carpineti is joined by experimental physicist and Alpha spokesperson Professor Jeffrey Hangst to understand the nature of mysterious antimatter.
