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.

![An artist’s concept looks down into the core of the galaxy M87, which is just left of centre and appears as a large blue dot. A bright blue-white, narrow and linear jet of plasma transects the illustration from centre left to upper right. It begins at the source of the jet, the galaxy’s black hole, which is surrounded by a blue spiral of material. At lower right is a red giant star that is far from the black hole and close to the viewer. A bridge of glowing gas links the star to a smaller white dwarf star companion immediately to its left. Engorged with infalling hydrogen from the red giant star, the smaller star exploded in a blue-white flash, which looks like numerous diffraction spikes emitted in all directions. Thousands of stars are in the background.]](https://assets.iflscience.com/assets/articleNo/76155/aImg/79193/jet-m.jpg)
