The effort to directly detect dark matter is well motivated by cosmology, astrophysics, and astronomical observation; in fact, the most recent cosmological study of the cosmic microwave background suggests that more than 25% of all the energy content in the universe is dark matter. The Large Underground Xenon experiment (LUX) is the world's most sensitive dark matter detector, located in the Sanford Underground Research Facility in Lead, SD. LUX is designed to observe weakly interacting massive particles (WIMPs)---a leading dark matter particle candidate---scattering off xenon nuclei in its 350-kg target volume of liquid xenon. Less than four months ago, the LUX experiment announced the results of its 85-day underground WIMP search. This talk will cover the world-leading results from this search, while also providing an overview of how the detector works, why it must operate nearly one mile below ground in an abandoned gold mine, and what lies ahead in the search for dark matter.
