She also carefully explains the distinction between primordial and secondary antimatter, and their roles in cosmology. In particular, Gato-Rivera discusses dark-matter and dark-energy candidates, attempts to detect dark matter and its relation to the fate of the universe. This touches upon the observed accelerating expansion of the universe. She then focuses on diverse aspects of antimatter science, beginning with the differences between antimatter, dark matter and dark energy, and the different roles they play in the universe. Gato-Rivera sets out with a detailed exploration of the differences between atoms and antiatoms, as well as of matter–antimatter annihilation, motivating the reader to delve into a fairly complete introduction to particle physics: the concepts that underpin the Standard Model, and some that lie beyond. Substantially extending her text Antimateria, from the outreach collection “Qué Sabemos De”, this work will also be of interest to experts, thanks to well documented anecdotes of historical interest. ![]() Beatriz Gato-Rivera, a former CERN fellow in theoretical physics and now a researcher at the Spanish National Research Council, recently published a noteworthy book on the subject, entitled Antimatter: What It Is and Why It’s Important in Physics and Everyday Life. ![]() Credit: CERNĪntimatter captivates the popular imagination. Antimatter: What It Is and Why It’s Important in Physics and Everyday Life, By Beatriz Gato-Rivera, Springer Annihilation An antiproton collides with an atom of gaseous neon in the PS-179 experiment at CERN’s Low-Energy Antiproton Ring in 1984.
