Web24 de nov. de 2024 · A famous article from 1962argued for the first scenario but the reality, we think, is more complex. 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. WebThe answer is that because light travels at a finite speed, the light from some things that we see now left them millions of years ago. And because the Universe is expanding, light such as this is redshifted; the more redshift, the longer the light has traveled to reach us. By observing very high redshift objects, we can look back in time.

The earliest stage in the evolution of galaxies is their formation. When a galaxy forms, it has a disk shape and is called a spiral galaxy due to spiral-like "arm" structures located on the disk. There are different theories on how these disk-like distributions of stars develop from a cloud of matter: however, at present, none of them exactly predicts the results of observation.
