What is the Cosmic Microwave Background Radiation? And what does it mean?

This video provides an overview of the accidental discovery and explanation of the cosmic microwave background radiation, the afterglow of the big bang. After reviewing the initial experimental work of Penzias and Wilson, a detailed account of the theoretical interpretation is presented, including a discussion of the thermodynamic legacy of the big bang, the Planck radiation law, recombination, and galaxy formation.
