(March 18, 2013) Leonard Susskind discusses the inhomogeneities in the cosmic microwave background, and derives the current theory whereby these inhomogeneities are created by quantum fluctuations in the inflaton field of the early universe. These fluctuations lead to variations in energy density that ultimately result in the formation of galaxies.

This is a lecture series from The Theoretical Minimum, a collection of lectures on classical and modern physics given by Stanford University professor Leonard Susskind, renowned theoretical physics and expert on string theory and modern cosmology. This course will concentrate on cosmology, the science of the origin and development of the universe. Along the way, students will take a close look at the Big Bang, the geometry of space-time, inflationary cosmology, cosmic microwave background, dark matter, dark energy, the anthropic principle, and the string theory landscape.
