We expected the attractive force of gravity to slow down the rate at which the Universe is expanding. But observations of very distant exploding stars (supernovae) show that the expansion rate is actually speeding up, a remarkable discovery that was honored with the 2011 Nobel Prize in Physics to the teams' leaders. Over the largest distances, the Universe seems to be dominated by a repulsive "dark energy" -- an idea Albert Einstein had suggested in 1917 but renounced in 1929 as his "biggest blunder." It stretches space itself faster and faster with time. But the physical origin and nature of dark energy, which makes up about 70% of the contents of the Universe, is probably the most important unsolved problem in all of physics; it may provide clues to a unified quantum theory of gravity. About the Speaker: Alex Filippenko is the Richard & Rhoda Goldman Distinguished Professor in the Physical Sciences. His accomplishments, documented in about 700 research papers, have been recognized by several major prizes, and he is one of the world's most highly cited astronomers. In 2009 he was elected to the National Academy of Sciences, and he shared part of the Gruber Cosmology Prize in 2007. He has won the top teaching awards at UC Berkeley and has been voted the "Best Professor" on campus a record 9 times. In 2006 he was selected as the Carnegie/CASE National Professor of the Year among doctoral institutions, and in 2010 he won the ASP's Emmons Award for undergraduate teaching. He has produced five astronomy video courses with "The Great Courses," coauthored an award-winning textbook, and appears in numerous TV documentaries including about 40 episodes of "The Universe" series. An avid tennis player, hiker, and skier, he enjoys world travel and is addicted to observing total solar eclipses (11 so far).

DARK UNIVERSE, the new Hayden Planetarium Space Show premiering November 2, 2013, at the American Museum of Natural History, is produced by an acclaimed team that includes astrophysicist and curator Mordecai-Mark Mac Low. Here, Dr. Mac Low gives an overview of what we know about the mysterious phenomenon of dark energy. DARK UNIVERSE celebrates the pivotal discoveries that have led us to greater knowledge of the structure and history of the universe and our place in it—and to new frontiers for exploration. The Space Show is narrated by astrophysicist Neil deGrasse Tyson. DARK UNIVERSE was created by the American Museum of Natural History, the Frederick Phineas and Sandra Priest Rose Center for Earth and Space, and the Hayden Planetarium. Made possible through the generous sponsorship of ACCENTURE. And proudly supported by CON EDISON. The Museum also gratefully acknowledges major funding from the Charles Hayden Foundation. Presented with special thanks to NASA and the National Science Foundation. DARK UNIVERSE was developed by the American Museum of Natural History, New York (www.amnh.org), in collaboration with the California Academy of Sciences, San Francisco and GOTO INC, Tokyo, Japan.

Updated: 01 Jan 2014

In 1998, two groups presented startling evidence that the expansion of the universe is accelerating, and the term "dark energy" was coined as a label for the cause of the acceleration. What is the nature of this mysterious component that we now believe makes up more than 70 percent of the energy density of the universe? What types of evidence for dark energy are there, and how solid is it? What techniques will yield better answers? What are the next steps? These are a few of the questions that have captured the attention of cosmologists as well as the general public. This talk will attempt to explain the questions and a few of the answers. von Kármán Lecture Speaker: Dr. Michael Seiffert JPL Research Scientist Release Date: 11 December 2008 Credit: NASA Jet Propulsion Laboratory (JPL)
