Dark matter is one of the most intriguing and important mysteries in modern science. On Saturday, April 18th, Dr. Anna Nierenberg will be the guest speaker at the AAUW Nevada County Branch monthly meeting where she’ll discuss The Cosmic Mystery You Can’t See: Why Dark Matter Matters. The meeting, which is free and open to the public, will be held 9:30-11:30AM at Peace Lutheran Church, 828 W. Main Street, Grass Valley.
An assistant professor of physics at the University of California, Merced, Dr. Nierenberg will explain what dark matter is, how scientists discovered it, and how we continue to search for it today. Designed for non-scientists who are curious about the universe and how scientific discovery works, Dr. Nierenberg’s presentation will offer clear explanations, compelling images, and real-world analogies to show how dark matter governs the motion of galaxies, helps explain why galaxies form the way they do, and provides crucial clues about the universe’s origins shortly after the Big Bang.
An assistant professor of physics at the University of California, Merced, Dr. Nierenberg’s work explores some of the deepest mysteries of the universe – most notably dark matter. She has earned prestigious honors including fellowships from the University of California and NASA, as well as a highly competitive National Science Foundation CAREER Award.
Although dark matter cannot be seen, touched, or directly detected with ordinary instruments, scientists know it exists because of its powerful influence on the universe. Dark matter outweighs all visible matter – stars, planets, and galaxies combined—and acts as the invisible framework that shapes how the universe is built and how it evolves over time.
Beyond its cosmic importance, the search for dark matter has meaningful impacts here on Earth. Efforts to detect dark matter have driven major advances in technology, including highly sensitive sensors, imaging techniques, data analysis methods, and particle detectors. These innovations have found practical uses in medical imaging, radiation detection, materials science, and national security. In addition, the massive data-analysis challenges posed by dark-matter research have helped advance computing, statistics, and artificial intelligence— tools that now shape everyday life.
The program is sponsored by Bodacious Blooms Flower Farm (Karen Hull) and Ponderosa Physical Therapy (Chelsea Lynch).
For more than 85 years, the AAUW Nevada County Branch has been striving to advance equity for women and girls through advocacy, education, philanthropy, and research. AAUW membership is open to individuals with an associate, baccalaureate, or higher degree from a qualified educational institution. For individuals interested in participating in branch interest groups and other activities, but who have not had the opportunity to complete a degree, the Nevada County Branch offers “Friends of AAUW” membership.
