Dark Matter, Dark Energy: The Dark Side of the Universe by Sean Carroll
Requirements: .MP3 reader, 508 MB
Overview: There’s more to the universe than meets the eye—a lot more. In recent years, scientists have discovered that 95% of the contents of the cosmos are invisible to our current methods of direct detection. Yet something is holding galaxies and galaxy clusters together, and something else is causing space to fly apart.Scientists call these invisible components dark matter and dark energy; “dark” because these phenomena do not emit light, not because we are not learning more and more about them. In fact, dark matter and dark energy are the most eagerly studied subjects in astronomy and particle physics today.If and when we discover this matter, it will further validate the “standard model” of physics which, so far, is the best description of how our universe works; if we cannot find this matter, or if it does not exist, then we will completely need to rethink the current “standard model” theory.Starting with the early 20th-century work of Albert Einstein in theoretical physics and Edwin Hubble in observational astronomy, Dr. Carroll takes you through the key concepts of this revolutionary view of an expanding universe, concepts which have brought us—for the first time in history—to the brink of knowing what the universe is made of.
