Abstract:
This review paper explores the nature and significance of dark matter (DM) and dark energy (DE), two enigmatic components that together make up approximately 95% of the universe's mass and energy. While dark matter is largely known for its gravitational effects, recent research suggests that it may also play a role in solar and planetary phenomena, potentially influencing processes such as the 11-year solar cycle and the heating of the solar corona. Similarly, dark energy, responsible for the accelerating expansion of the universe, remains a subject of intense debate, with various models, including the cosmological constant and more dynamic alternatives, under investigation. This paper discusses different candidates for DM, including exotic objects like dark neutron stars and black holes, and examines the possibility of unified models for both DM and DE. Additionally, it reviews alternative theories such as Modified Newtonian Dynamics (MOND) and modified gravity, highlighting their potential to challenge existing cosmological models. The paper concludes by emphasizing the need for further observational efforts and cross-disciplinary approaches to advance our understanding of these cosmic phenomena.
