It’s hard to wrap your mind around the idea of an ever-expanding universe. But that’s what this year’s winners of the Nobel Prize in Physics did back in 1998. Using the best tools and minds that science has to offer, two distinct teams of scientists, one led by Lawrence Berkeley Laboratory and University of California Berkeley Professor Saul Perlmutter, arrived at the same conclusion — that the universe is not only expanding, it’s accelerating.
In addition to Professor Perlmutter at the Supernova Cosmology Project, the other half of this prestigious prize was awarded jointly to Brian P. Schmidt at Australian National University and Adam G. Riess at Johns Hopkins University and Space Telescope Science Institute. You can find the official announcement from the Nobel Prize organization here.
In January 2010, UCTV premiered a program from Lawrence Berkeley Lab featuring Saul Perlmutter, along with his colleagues Alexie Leauthaud of the Berkeley Center for Cosmological Physics and David Schlegel of Baryon Oscillation Spectroscope Survey, in a public conversation about the suspected cause of the universe’s accelerated expansion, dark energy, an elusive force that remains science’s biggest unsolved mystery.
