Researchers Find Last of Universe’s Missing Ordinary Matter

Researchers at the University of Colorado Boulder have helped to find the last reservoir of ordinary matter hiding in the universe. Ordinary matter, or “baryons,” make up all physical objects in existence, from stars to the cores of black holes. But until now, astrophysicists had only been able to locate about two-thirds of the matter that theorists predict was created by the Big Bang.
In the new research, an international team pinned down the missing third, finding it in the space between galaxies. That lost matter exists as filaments of oxygen gas at temperatures of around 1 million degrees Celsius, said CU Boulder’s Michael Shull.
