In this lecture based on a chapter in his book, The Believing Brain, Dr. Shermer outlines how controversies in science are resolved by looking at the centuries-long debate over the nature of the cosmos, its size and origin, and what those fuzzy patches in the sky are: nebula within the Milky Way galaxy or island universes? It was not clear until well into the 20th century that the Milky Way was not the entire universe, until Edwin Hubble working at Mt. Wilson Observatory determined that the universe is much larger than anyone had previously imagined it to be.
