Galaxy formation refers to the process by which galaxies, massive gravitationally bound systems consisting of stars, stellar remnants, and interstellar gas, come into existence and evolve over billions of years. Understanding galaxy formation is crucial for the tech community, particularly in the fields of astrophysics and cosmology, as it sheds light on the fundamental nature of the universe and informs the development of advanced telescopes and simulation technologies that help scientists study the origins and evolution of the cosmos.
