Physicists appropriate Halloween with Dark Matter Day—watch the video!

Because physics has its dark mysteries too, we have appropriated Halloween! Watch our Dark Matter Day video on our YouTube channel!

Watch the short video Dark Matter and hear leading-edge scientists explain what we know about one of the greatest mysteries of our time. What could it be? How do we know it’s there? And what ingenious methods are scientists, working in different subdisciplines of physics and astronomy around the globe, using to detect dark matter?

Astrophysicist Jeff Filippini, astronomer Felipe Menanteau, experimental nuclear physicist Liang Yang, theoretical particle physicist Jessie Shelton, and experimental particle physicist Ben Hooberman provide an accessible overview of some of the most exciting scientific research that is ongoing today.

This educational outreach video was produced by the Department of Physics at the University of Illinois at Urbana Champaign, under the direction of U of I Public Affairs Video Services.

Because the muon can emit and reabsorb any particle, its magnetism tallies all possible particles—even new ones too massive for the LHC to make. Other charged particles could also sample this unseen zoo, says Aida El-Khadra, a theorist at the University of Illinois in Urbana. But, she adds, "The muon hits the sweet spot of being light enough to be long-lived and heavy enough to be sensitive to new physics."

There is remarkable biodiversity in all but the most extreme ecosystems on Earth. When many species are competing for the same finite resource, a theory called competitive exclusion suggests one species will outperform the others and drive them to extinction, limiting biodiversity. But this isn’t what we observe in nature. Theoretical models of population dynamics have not presented a fully satisfactory explanation for what has come to be known as the diversity paradox.

As acting president of Ginling College, Minnie Vautrin (Illinois class of 1912) sheltered more than 10,000 Chinese women from rape and deadly violence during the Nanjing Massacre. The Program in Arms Control & Domestic and International Security (ACDIS) at Illinois will host a symposium recalling the history of the Sino-Japanese war and honoring Vautrin. The Forgotten Holocaust of World War II: The Massacre of Nanjing will be held on December 16, 2017, at the Levis Faculty Center, Room 300, 919 West Illinois Street, Urbana.
