24 lectures, 30 minutes/lecture Taught by Sean Carroll California Institute of Technology Ph.D., Harvard University There's more to the universe than meets the eyea lot more. In recent years scientists have discovered that 95 percent of the contents of the cosmos are invisible to all of our current methods of direct detection. Yet they are definitely there: Something is holding galaxies and galaxy clusters together, and something else is causing space itself to fly apart. Scientists call these invisible components dark matter and dark energy"dark" because these phenomena don't emit light, not because we aren't learning more and more about them. Indeed, dark matter and dark energy are the most eagerly studied subjects in astronomy and particle physics today. And for good reasonwhat could be more exciting than cracking the mystery of the fundamental constituents and overall composition of the universe? A Mind-Expanding Experience You can join the search in this mind-expanding course of 24 lectures taught by a scientist with a profound knowledge of the field. A theoretical physicist at the California Institute of Technology, Dr. Sean Carroll has a knack for explaining the latest complex picture of the universe in easy-to-follow termsa skill honed through his many public lectures and radio and television appearances. You will find Dr. Carroll relaxed, eloquent, wryly funny, and brimming with ideas as he takes you on a voyage of scientific discovery. He starts with the early 20th-century work of Albert Einstein in theoretical physics and Edwin Hubble in observational astronomytwo masters who contributed key insights to the revolutionary view of an expanding universe. The powerful elaboration of these concepts has brought us, for the first time in history, to the brink of knowing what the universe is made of.
