Mysteries of Modern Physics: Time" Prof. Sean Carroll (DVD) (24 Lectures / 30 Minutes Per Lecture /  4x DVD - The Great Courses)
The fundamental nature of time is explored through the lens of contemporary physics, moving from everyday experiences to the most complex theories of the universe. It addresses why time seems to flow in only one direction and how the laws of entropy dictate the transition from order to disorder. By examining the foundations of relativity and quantum mechanics, the curriculum reveals how our understanding of "now" is far more complicated than it appears on the surface.
 
The lectures also investigate the connection between the arrow of time and the origins of the cosmos, including the Big Bang and the eventual fate of the universe. It tackles mind-bending concepts like time dilation, the possibility of time travel, and the relationship between time and space. The objective is to provide a clear scientific framework for one of the most mysterious aspects of reality, connecting the behavior of subatomic particles to the grand scale of the entire galaxy.
