gravity

The creation of a galaxy is a complex process that begins with the collapse of a massive cloud of gas and dust. These clouds, which are known as nebulae, can contain millions of times the mass of the sun. As the cloud collapses, it begins to spin, creating a disk-shaped structure with a dense central region. Within the central region of the disk, the gas and dust become so compressed that nuclear fusion reactions are ignited, creating a new star. These stars can be extremely massive, and their intense radiation and stellar winds can push away the remaining gas and…
