Title: The Dark Side of the Universe: The quest to uncover the fundamental nature of dark matter
Abstract: Approximately 85% of the matter in the Universe is thought to be a mysterious substance called dark matter that neither emits nor absorbs light and only interacts with normal matter via gravity. Ninety years have elapsed since the first evidence for dark matter emerged from astronomical observations, but its fundamental nature remains one of the greatest cosmic mysteries. In this talk we will explore the abundant evidence for dark matter in galaxies and clusters of galaxies. Then, we will consider some of the possibilities for what dark matter might be. Finally, we'll talk about some of the exciting physics experiments that are trying to directly detect dark matter particles on Earth and some of the new astronomical observations that will shed light on its fundamental nature.
Because of the cloudy weather forecast, we will not have open telescopes at the Observatory tonight.
