Relate dark matter to the development of the universe after the Big Bang. In 3-5 sentences, speculate on how the development of the universe would have been different if there had been no dark matter. In your answer, use the term structures.(4 points)

Dark matter plays a crucial role in the development of the universe after the Big Bang. It is believed to provide the gravitational pull necessary for the formation of large-scale structures, such as galaxies and galaxy clusters. Without dark matter, the gravitational interactions that led to the formation of these structures would have been significantly weaker, resulting in a less organized and smaller-scale universe. Additionally, the absence of dark matter could have influenced the distribution of normal matter, potentially altering the formation of stars and planets.
