Grounds for Science – Searching for Dark Matter

October 27, 2017 @ 6:30 pm

- Free

A Lighthouse on the Dark Cosmic ShoreMost of our universe is held together by invisible material aka “dark matter.” We have no idea what dark matter is made of or how it came to exist in the first place. Come hear about how we might solve this mystery with the recent discovery of gravitational waves from merging black holes! You’ll also learn about an alternative method of searching for dark matter that (ironically) uses light from objects called pulsars which pulsate with more stability than an atomic clock. You won’t want to miss this chance to hear about some of the crazy stuff just sitting out there in space!Speaker: Katelin Shutz UC BerkeleySearching for the invisible a mile underground How One Technique Unites Them AllDark matter is a mysterious substance that makes up twenty-five percent of our universe. We can see the effect of this matter on a huge scale – it changes the rotation of galaxies and bends light from distant astronomical objects – but we are in the dark when it comes to detecting the essential particles that constitute it. The Large Underground Xenon (LUX) experiment is a 300 kg dark matter detector at the bottom of an abandoned gold mine. A mile underground in the Black Hills of South Dakota LUX utilizes liquid xenon to shed light on this elusive particle.Speaker: Elizabeth Boulton Lawrence Berkeley National Labs
