"Dark Matter, Dark Energy: The Dark Side of the Universe" Prof. Sean Carroll (DVD) (24 Lectures / 30 Minutes Per Lecture /  4x DVD - The Great Courses)
The enigmatic composition of the unseen 95% of the cosmos takes center stage in this high-impact series exploring the most profound mysteries of modern cosmology. These lectures provide an exacting assessment of the invisible forces that govern the large-scale structure of the universe, moving far beyond the 5% of "ordinary" matter we can observe with telescopes. By analyzing the latest breakthroughs in theoretical physics and observational astronomy, the course investigates how dark matter acts as the cosmic glue holding galaxies together, while dark energy drives the accelerating expansion of space itself.
 
A sophisticated scientific lens replaces surface-level speculation to investigate the fundamental building blocks of reality, from the standard model of particle physics to the geometry of space. Drawing on expertise from the California Institute of Technology, this material explores the evidence for relic particles from the Big Bang and evaluates controversial theories like quintessence and extra dimensions. This is not merely a survey of astronomical facts; it is an invitation to master the scientific principles that define the origin, evolution, and ultimate fate of our dark universe.
