Dr. Tom Shutt, Stanford Linear Accelerator Ctr & Kavli Institute
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. Shutt 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.
