DOE 40th Anniversary Milestone: Expansion of Universe is Speeding Up Scientists assumed the universe's expansion was slowing down as gravity pulled debris from the Big Bang back together. But in 1999 Saul Perlmutter and others discovered the universe's expansion is speeding up, driven by an unknown cause referred to as "dark energy." They used measurements from Type 1a supernovae, which all reach maximum brightness when they explode. More>
The Hunt for Dark Matter With LUX-ZEPLIN This video from SLAC National Accelerator Laboratory explains how the upcoming LZ experiment will search for the missing 85 percent of the matter in the universe. Berkeley Lab physicists are among the researchers participating in the LZ experiment. More>
Story Highlights Oliver-Mallory’s Work at the Sanford Underground Lab Kelsey Oliver-Mallory’s first few cage rides to the 4850 Level “felt like an adventure,” she said. Now, her trip to the Black Hills State University Underground Campus where she works in the low-background counting facility has become routine. But she still loves going to work there. Oliver-Mallory is a UC Berkeley graduate student working in the Lab’s Physics Division. More>
Lab Physicist Gives August 19 Campus Talk on the Higgs Boson Heather Gray of the Physics Division will introduce the complex experiments that are used to study the Higgs Boson particle and explain how researchers go about measuring its properties.
