Multiple lines of astronomical evidence show the existence of dark matter and dark energy — mysterious stuff whose gravity holds galaxies together and drives the accelerated expansion of the universe, respectively. Physicists have long assumed that this "dark sector" would at least partially consist of new, relatively massive particles, but have not been able to turn up clear evidence for them. A dark sector made of very light particles, however, could have escaped detection, yet is compatible with all astronomical and cosmological evidence. Precision measurements in physics are suitable to searching for such ultralight dark-sector candidates.
Dr. Holger Müller, Professor of Physics at UC Berkeley, will present a FREE popular-level slide show on his work to understand The Dark Side. Bring a flashlight; and, just in case, wear warm clothes in layers. If bad weather threatens, call 415-455-5370 after 4pm. This event is co-produced by Wonderfest, the Mount Tam Astronomy Program, Mt. Tamalpais State Park, Friends of Mt. Tam, and the San Francisco Amateur Astronomers. Sky tour and telescope viewing will follow
When & Where
Wonderfest, the San Francisco Bay Area Beacon of Science, is a non-profit educational corporation with 501(c)(3) tax exempt status. Wonderfest was founded by executive director Tucker Hiatt (email@example.com). Eric Yao (firstname.lastname@example.org) is technical director and board chairman. Wonderfest headquarters are located just north of San Francisco—in Marin County—at 47 Alta Way, Corte Madera, CA 94925.
Wonderfest’s Mission is to inspire and nurture a deep sense of wonder about the world: stimulating curiosity, promoting careful reasoning, challenging unexamined beliefs, and encouraging life-long learning. Wonderfest achieves these ends through public science gatherings in the San Francisco Bay Area and through online science discourse & video that reach around the world.
Science for whom?
The scientific endeavor has universal appeal. Every inquisitive person, regardless of culture or gender or income, is improved by the intellectual challenge and reward that science offers. Wonderfest presentations reach people of diverse ages, too; they appeal to the student in all of us, no matter how old. After all, if you’re through wondering, … you’re through! Wonderfest events are suitable for students in high school, in college, in the school of hard knocks, and in retirement communities.
…to celebrate the scientific spirit! The rational investigation of our world is the grandest human adventure, with the most significant long-term implications imaginable. Nevertheless, our science is fragile. It’s a small flame nourished in each of us by skepticism, by humility, and, above all, by wonder.
