Abstract: Our understanding of the universe is undergoing a revolution. Astronomical measurements have demonstrated that about 21% of universe is in the form of "dark matter," which gravitationally attracts but is otherwise invisible and most of the remainder (75%) takes the form of "dark energy," which causes space to expand at an ever-increasing rate. This implies that only a small fraction of the universe is matter that we understand! In this presentation, we will explore the evidence for dark matter and dark energy, as well as the experiments being developed to investigate their fundamental nature.
