Discovering Dark Matter
Scientific ideas build on one another, and access to information is important because it can lead to great discoveries. Case in point: dark matter. This hypothetical form of matter is thought to account for approximately 85% of the matter in the universe and about a quarter of its total energy density. But how did we move on from a model of the solar system that put Earth (and ourselves) at the center? And what can dark matter tell us about the laws of physics and the physical processes happening in the universe?
Join us to learn about how we can use light and what we know of the laws of nature here on Earth to study objects billions of light years away.
About the Speaker
JoEllen McBride is a mom, a science communicator, and an astrophysicist whose main purpose is to make science inclusive and accessible to everyone who wants to participate. She earned her PhD in physics from the University of North Carolina, Chapel Hill, in 2016. Her research focused on galaxies that live close to each other and how that affected their ability to create stars. After graduation she was a AAAS Mass Media Fellow at Voice of America in Washington, D.C., and an adjunct faculty member in the physics department at West Chester University. She is currently a communications and stewardship writer for the Penn Medicine Development and Alumni Relations Office.
About the Series
Dive into fascinating stories of science with our Saturday speaker series!
Every month a speaker will offer a short talk on an intriguing scientific topic, followed by a Q&A or discussion over complimentary tea and coffee. Afterward, feel free to mingle with other guests and the speaker, or spend time visiting our free museum. This year we’ll be discussing everything from the history of chocolate, to how stress affects our DNA, to the ways artwork inspires scientific discovery.
Admission is free, and no reservations are necessary.
