Canceled: Darkness Surrounds Us: The Other 95% of the Universe

This event has been canceled due to the COVID-19 situation. All the material we can see is just a small fraction of the universe. The rest, a full 95%, is invisible and mysterious. These are the enigmatic dark matter and dark energy. While dark matter keeps things like galaxies together, dark energy acts in an opposite way—it pushes groups of galaxies apart and expands the universe itself. Dr. Alina Kiessling, a native of Melbourne, Australia and Dr. Jason Rhodes, a native of Des Moines, Iowa are both astrophysicists with the NASA-Jet Propulsion Laboratory. They will discuss dark energy and dark matter and how these can help us understand if the universe will expand at an accelerating rate forever.
