Baryonic matter is the 'normal' matter that makes up the atoms in the universe, including protons, neutrons, and electrons, and constitutes only about 5% of the universe's total mass-energy content. It is distinct from dark matter and dark energy, which together account for the Remaining 95% and are not composed of baryons.
