where is most of the baryonic matter (ordinary matter) of the universe found
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.
Most of the baryonic matter in the universe is found within galaxies. Within galaxies, the baryonic matter is primarily concentrated in stars, gas clouds, and dust.
Most of the baryonic matter, or ordinary matter, in the universe is found in two main locations: within galaxies and in the vast cosmic web of filaments connecting galaxies.
To understand this concept, we need to follow a logical step-by-step process.
1. Start with the Big Bang: The universe began with a tremendous explosion, known as the Big Bang. During this event, matter and energy were created in abundance.
2. Formation of Baryonic Matter: Baryonic matter, which consists of protons, neutrons, and electrons, emerged from the high-energy state of the early universe. This matter formed the building blocks for galaxies, stars, and other celestial objects.
3. Gravitational Clumping: Over billions of years, matter started to clump together due to the force of gravity. Initially, tiny density fluctuations in the early universe amplified, creating regions of slightly higher density than their surroundings.
4. Galaxy Formation: Within these denser regions, called dark matter halos, ordinary matter started to accumulate. The gravitational pull of the dark matter halos attracted gas and dust, eventually leading to the formation of galaxies. Galaxies contain the majority of the baryonic matter in the universe.
5. Cosmic Web: However, it's important to note that the distribution of matter in the universe is not just confined to galaxies. There are cosmic filaments, or threads, that connect galaxies and form a vast network called the cosmic web. These filaments, made up of dark matter and gas, contain a significant amount of baryonic matter, although it is less concentrated than within galaxies.
In conclusion, most of the baryonic matter in the universe can be found within galaxies, while a substantial amount also exists within the cosmic web, connecting and surrounding galaxies.
