Part 9/10:
Despite the compelling evidence regarding dark matter's critical role in cosmic structure and evolution, its definitive nature and existence remain open questions. The lack of direct detection of dark matter particles has led to alternative hypotheses, such as Modified Newtonian Dynamics (MOND), which seeks to describe gravitational effects without dark matter. However, the vast majority of gravitational observations favor the dark matter model, highlighting the necessity of ongoing research.
While some argue recent findings from the James Webb Space Telescope could challenge dark matter’s framework, the overwhelming foundational evidence from decades of study underscores its essential nature in our universe.
