Explore the mysteries of dark matter in this 36-minute keynote presentation from the APS April Meeting 2014 Fred Kavli Keynote Plenary Session. Delve into the compelling evidence for dark matter's existence, spanning from moments after the Big Bang to present-day observations across cosmic scales. Examine the current state of dark matter research, including the latest experimental efforts and theoretical models. Learn about various detection methods, such as collider experiments, searches for dark matter annihilation products, astrophysical observations, and direct detection techniques. Discover how these approaches are probing different aspects of dark matter, from its interactions with known particles to its self-interactions. Gain insights into promising dark matter candidates like Axions and Weakly Interacting Massive Particles (WIMPs), and understand the challenges in identifying the nature of this elusive substance. Follow the exciting progress being made in the quest to unravel one of the most significant mysteries in modern physics and cosmology. Read more
