<p>Astronomers today understand that the universe is full of a mysterious substance they call “dark matter” (because it doesn’t give off any light or other radiation we can detect.)  Dr. Tom Shutt (of the Stanford Linear Accelerator Center) discusses the motivation behind the multi-decade, world-wide effort to test the idea that dark matter is in the form of particles as small as a neutrino but as heavy as an atom.  He describes the experiment he is involved with, that uses 7 tons of liquefied Xenon to measure how these particles interact with normal matter.</p>

The Hunt for Dark Matter in the Universe with Dr. Tom Shutt

Listen to exciting, non-technical talks on some of the most interesting developments in astronomy and space science.  Founded in 1999, the Silicon Valley Astronomy Lectures are presented on six Wednesday evenings during each school year at Foothill College, in the heart of California's Silicon Valley. Speakers include a wide range of noted scientists, explaining astronomical developments in everyday language. The series is organized and moderated by Foothill's astronomy instructor emeritus Andrew Fraknoi and jointly sponsored by the Foothill College Physical Science, Math, and Engineering Division, the SETI Institute,  the Astronomical Society of the Pacific, and the University of California Observatories (including the Lick Observatory.)
