He then discusses concepts such as epicycles, dark energy and daOther Constraints: The Cosmic Microwave Backgroundhttp://studyportal.de/video/217/Other+Constraints%3A+The+Cosmic+Microwave+BackgroundReasons for the expansion of the universe are addressed at the start of this lecture, focusing especially on the acceleration of dark energy. Supernovae were the first evidence for the existence of daSupernovaehttp://studyportal.de/video/214/SupernovaeProfessor Bailyn offers a review of what is known so far about the expansion of the universe from observing galaxies, supernovae, and other celestial phenomena. The rate of the expansion of the univerDark Energy and the Accelerating Universe and the Big Riphttp://studyportal.de/video/211/Dark+Energy+and+the+Accelerating+Universe+and+the+Big+RipClass begins with a review of the mysterious nature of dark matter, which accounts for three quarters of the universe. Different models of the universe are graphed. The nature, frequency, and durationDark Matterhttp://studyportal.de/video/208/Dark+MatterThis lecture introduces an important concept related to the past and future of the universe: the Scale factor, which is a function of time. With reference to a graph whose coordinates are the Scale faOmega and the End of the Universehttp://studyportal.de/video/206/Omega+and+the+End+of+the+UniverseClass begins with a review of the issues previously addressed about the origin and fate of the universe. The role of gravity in the expansion of the universe is discussed and given as the reason why tHubble's Law and the Big Bang (cont.2)http://studyportal.de/video/203/Hubble%27s+Law+and+the+Big+Bang+%28cont.2%29Professor Bailyn returns to the subject of the expansion of the universe to offer explanations that do not require belief in the Big Bang theory. One alternative is a theory that, in the past, the entHubble's Law and the Big Bang (cont.)http://studyportal.de/video/202/Hubble%27s+Law+and+the+Big+Bang+%28cont.%29Class begins with a review of magnitudes and the problem set involving magnitude equations. Implications of the Hubble Law and Hubble Diagram are discussed. Professor Bailyn elaborates on the Big BangHubble's Law and the Big Banghttp://studyportal.de/video/199/Hubble%27s+Law+and+the+Big+BangThe third and final part of the course begins, consisting of a series of lectures on cosmology. A brief history of how cosmology developed into a scientific subject is offered. The discovery of dark eSupermassive Black Holeshttp://studyportal.de/video/195/Supermassive+Black+HolesThe lecture begins with a question-and-answer session about black holes. Topics include the extent to which we are sure black holes exist in the center of all galaxies, how massive they are, and how wPulsarshttp://studyportal.de/video/191/PulsarsProfessor Bailyn begins with a summary of the four post-Newtonian effects of general relativity that were introduced and explained last time: precession of the perihelion, the deflection of light, theStellar Mass Black Holes (cont.)http://studyportal.de/video/189/Stellar+Mass+Black+Holes+%28cont.%29Class begins with clarification of equations from the previous lecture. Four post-Newtonian gravitational effects are introduced and discussed in detail. The first of these is the so-called PerihelionStellar Mass Black Holeshttp://studyportal.de/video/175/Stellar+Mass+Black+HolesOne last key concept in Special Relativity is introduced before discussion turns again to black celestial bodies (black holes in particular) that manifest the relativistic effects students have learneSpecial and General Relativity (cont.)http://studyportal.de/video/164/Special+and+General+Relativity+%28cont.%29The lecture begins with a comprehensive overview of the historical conditions under which Einstein developed his theories. Of particular impact were the urgent need at the turn of the 19th century to Special and General Relativityhttp://studyportal.de/video/160/Special+and+General+RelativityThe discussion of black holes continues with an introduction of the concept of event horizon. A number of problems are worked out to familiarize students with mathematics related to black hole event hPlanetary Systems Around Other Starshttp://studyportal.de/video/153/Planetary+Systems+Around+Other+StarsGuest lecturer Dr. Geoff Marcy gives a lecture entitled, "Planetary Systems Around other Stars," for Professor Lynn Rothschild's Astrobiology and Space Exploration course.
