This summer PBL is designed to help us understand the formation of the universe, as well as the formation of galaxies. We spent the class time going through vocabulary words, the stages of universe expansion, signs of the big bang, researching dark matter, dark energy, the theory of relativity, etc. During our final session of class time, we researched a lot of information about the inflation period, specifically how the inflation period solved 4 major issues, as well as 3 different experiments that are searching for dark matter. In this write-up, I am going to summarize and explain all of the research we did.
