Explore the fascinating world of cosmology in this 1-hour 27-minute conference talk from the World Science Festival. Delve into the study of cosmic background radiation and its role in understanding the universe's origins and evolution. Learn about groundbreaking discoveries, including the confirmation of early space expansion, the universe's geometric shape, and the identification of galaxy seeds. Discover how leading scientists, including Nobel Laureate John Mather, are using this ancient light to uncover when the first stars formed and what occurred in the moments after the Big Bang. Follow the journey from early experiments to cutting-edge projects like COBE and EBEX, and explore concepts such as measuring minute temperature differences, gravity waves, and the limits of our ability to observe the early universe. Gain insights into the scientific process, future research directions, and fundamental questions about the nature of matter and the size of the cosmos.
