Explore the origins of the universe in this 56-minute lecture by renowned experimental cosmologist Lyman Page. Delve into the cosmic microwave background (CMB) and its significance in revealing the universe's age, size, and geometry. Learn how tiny variations in the CMB serve as a blueprint for cosmic structure formation. Discover the Standard Model of Cosmology, understand the concept of cosmic expansion, and grasp how telescopes function as time machines due to the finite speed of light. Examine the measurements crucial to the Standard Cosmological Model, investigate the formation of hot and cold patches in the early universe, and unravel the mysteries of cosmic paleontology. Gain insights into the angular power spectrum and the parameters that shape our understanding of the cosmos.
