Fundamentals of Dark Matter and Modern Cosmology

Dark matter accounts for the vast majority of matter in the universe, yet it remains invisible to traditional electromagnetic instruments. This text-based guide breaks down the core physics, key observational evidence, and leading theoretical models that define our modern understanding of this cosmic phenomenon. You will gain a thorough conceptual foundation in modern cosmology and learn how astrophysicists infer the presence of unseen mass across galaxies and clusters. What you'll learn: - Understand foundational cosmological terminology, basic physics principles, and the historical discovery of missing mass - Analyze galactic rotation curves and gravitational lensing as key observational indicators - Evaluate leading dark matter particle candidates, including WIMPs, axions, and sterile neutrinos - Explore alternative theoretical frameworks, such as Modified Newtonian Dynamics, and compare their explanatory scope - Examine the role of dark matter in cosmic structure formation and cosmic microwave background observations - Review current experimental detection approaches across direct, indirect, and collider research programs. The course begins with essential terminology and fundamental definitions before systematically walking you through modern cosmological frameworks and evidence. This course is designed for beginners, science enthusiasts, and curious readers, requiring no advanced mathematics or prior astrophysics background. Expand your scientific knowledge and explore the universe's greatest mystery today.
