Alexei Filippenko presents "Dark Energy and the Runaway Universe" at the 49th annual Nobel Conference: The Universe at Its Limits. Which took place at Gustavus Adolphus College in 2013.
Alexei V. Filippenko, Ph.D. is the Richard and Rhoda Goldman Distinguished Professor in the Physical Sciences, Department of Astronomy, University of California, Berkeley.
One of the world’s most highly cited astronomers, Alexei Filippenko was a member of the Supernova Cosmology Project and the High-z Supernova Search Team that used observations of extragalactic supernovae to prove the accelerating expansion of the universe and thus imply the existence of “dark energy.” The discovery was voted the top science breakthrough of 1998 by Science magazine and earned the teams’ leaders the 2011 Nobel Prize in physics. Filippenko also works on quantifying the physical properties of quasars and active galaxies and searches for black holes in both X-ray binary stars and nearby galactic nuclei.

The Nobel Conference: Science and Ethics, in Dialogue
Since 1965, the Nobel Conference has been bringing leading researchers and thinkers to Gustavus Adolphus College in Saint Peter, Minnesota, to explore revolutionary, transformative and pressing scientific issues and the ethical questions that arise alongside them.
As the only event in the United States authorized by the Nobel Foundation in Stockholm, Sweden to use this name, it is our privilege to host a space in which we can talk about big scientific questions, and the big ethical issues to which they inevitably give rise. The world needs more people who think critically about the crucial issues of our time, and who ask questions in ways that open up the conversation.
