In the prevailing theory, the formation of a galaxy can be divided into three stages: 1. A ‘primordial collapse’ of matter into a clump in the early, expanding Universe. 2. Hierarchical structure formation of larger clumps from smaller clumps. 3. WebWhen galaxies grew in the first billion years, light from their hot stars spread into the surrounding intergalactic gas, producing bubbles of ionized gas around them. As galaxies continued to grow, so did the ionized bubbles – reionizing all hydrogen. slsa supply chain
