How are galaxies formed?
Galaxies are vast systems of stars, gas, dust, and dark matter that are held together by gravity. Scientists believe that galaxies are formed through a process called hierarchical clustering, in which smaller structures, such as protogalaxies and galaxy groups, come together to form larger structures over time. These structures are fueled by a combination of gravitational collapse, accretion of gas and dust, and mergers with other galaxies. The exact process of galaxy formation is still a subject of ongoing research and debate, but scientists have made significant progress in understanding the mechanisms involved.
