Question

where is most of the baryonic matter (ordinary matter) of the universe found

Answer 1

Most of the baryonic matter (ordinary matter) in the universe is found in the form of galaxies and galaxy clusters. Galaxies are vast collections of stars, gas, and dust held together by gravity, and they make up a significant portion of the baryonic matter. Galaxy clusters, on the other hand, are clusters of galaxies held together by their collective gravitational pull. Additionally, smaller amounts of baryonic matter can be found in intergalactic space, including in the form of hot gas and dust.
