Where Does the Cosmic Microwave Background Come From?

We know that the universe is filled with a background radiation that is a relic of the Big Bang. How was it discovered? Who came up with the idea? How do we observe it? How do we know it's really there? Where did it come from? This is the sixth of the videos in my new series of Cosmology. I'm going through Dr. Barbara Ryden's textbook "Introduction to Cosmology". If you follow along, you'll get a full upper-division undergraduate course in Cosmology. I used this textbook at William Paterson University. This course will cover the current state of the science of Cosmology. To follow along, it'll be a good idea for you to ge to know your calculus. Here are the topics of this video: Introductory Cosmology Chapter 02: Fundamental Observations Section 05: Cosmic Microwave Background Some things covered: The Nature of Photons. Blackbody Radiation. An overlooked origin story to the CMB, starring: Ralph Alpher, Robert Hermann, George Gamove, Arno Penzias, Robert Wilson, and Robert Dicke. COBE, WMAP, and Planck CMB Missions.
