While observational tests on the specifics of cosmology progress rapidly, astronomers are concentrating on the mechanics of how the universe's matter first came together. Galaxies, stars, or black holes? That is the fundamental conundrum. Due to the gravitational influence of dark matter, it is inferred that the universe began as a relatively uniform sea of several thousand-degree plasma and dark matter, which is an unseen, enigmatic, and predominate form of matter. The key to solving the early universe's riddle is to comprehend how galaxies, stars, and black holes joined together. Based on data from the cosmic microwave background, astronomers believe that matter coalesced when the universe cooled and became "transparent" 380,000 years after the Big Bang. And according to recent research, structures like stars and galaxies formed as early as 200 million years following the Big Bang. However, future research is necessary to determine precisely how matter clumped. #cosmos #planet #universe
