Delve into the mysteries of the universe in this captivating 1 hour 44 minute conference talk from the World Science Festival. Explore the enigmatic 96% of the cosmos that remains invisible to our telescopes, consisting of dark matter and dark energy. Learn how these unseen forces shape the formation of galaxies and influence the far reaches of space. Join leading researchers as they discuss their groundbreaking work, from particle collisions to underground experiments, in the quest to understand nature's dark side. Discover how familiar matter accounts for only 4% of the universe's weight, and how dark matter and energy play crucial roles in the universe's past, present, and future. Gain insights into cutting-edge detection methods, including the XENON100 detector and supernova observations. Examine the implications of Einstein's predictions about dark energy and explore competing theories. Reflect on how the perfect ratio of dark energy may create an ideal environment for life in the cosmos.
