Heart of Darkness with Jeremiah Ostriker

Over the past 30 years, scientists have learned that dark matter and dark energy, both poorly understood, comprise most of the known cosmos, explain the growth of all cosmic structure, and hold the key to the fate of the universe. Astrophysicist Jeremiah Ostriker tells the story of how the evidence for the so-called “Lambda-Cold Dark Matter” model of cosmology has been gathered by generations of scientists.
