Web17 de abr. de 2024 · Scientists have inferred that helium hydride was this first, primordial molecule. Once cooling began, hydrogen atoms could interact with helium hydride, leading to the creation of molecular hydrogen — the molecule primarily responsible for the formation of the first stars. WebInitially, various kinds of subatomic particles are formed in stages. These particles include almost equal amounts of matter and antimatter, so most of it quickly annihilates, leaving a small excess of matter in the universe. At about one second, neutrinos decouple; these neutrinos form the cosmic neutrino background (CνB).

This... WebHow where atoms able to form after the big bang? From my understanding all the materials to form atoms were floating around and by random chance they collided and created atoms. If the universe was quickly expanding after the big bang, would the materials to form atoms be spread too thin.
Baryonic matter forms about 4% of the total energy density of the observable universe, with an average density of about 0.25 particles/m (mostly protons and electrons). Within a galaxy such as the Milky Way, particles have a much higher concentration, with the density of matter in the interstellar medium (ISM) ranging from 10 to 10 atoms/m . The Sun is believed to be inside the Local Bubble, so the density in the solar neighborhood is only about 10 atoms/m . Stars form fro…
