The Last of the Universe’s Ordinary Matter Has Been Found

This article discusses the recent discovery of the missing ordinary matter in the universe, known as baryons. Scientists have long been searching for the missing matter, as previous observations could only account for a fraction of what was predicted by theoretical models. Using a technique called the Sunyaev-Zel'dovich effect, scientists detected the baryons in the form of hot gas filaments stretching between galaxies. This discovery provides further evidence for our current understanding of the structure and composition of the universe. It also has implications for our understanding of the formation and evolution of galaxies. Overall, the article highlights the importance of uncovering the missing ordinary matter and its significance in advancing our knowledge of the cosmos.
