Podcast: The 4 Percent Universe with Richard Panek
by AMNH on
In recent years, a radically new vision of the universe has emerged: only 4 percent of it consists of every planet, star, and galaxy. The rest—96 percent—is completely unknown. How did astronomers reach this cosmos-shattering conclusion, and what are they doing to find dark matter and an even more bizarre substance called dark energy?
In this podcast from the winter, join Richard Panek, author of The 4 Percent Universe: Dark Matter, Dark Energy, and the Race to Discover the Rest of Reality.The book presents an intimate portrait of the bitter rivalries and fruitful collaborations, the blind alleys and the eureka moments, that are redefining science and reinventing the universe.
Panek’s talk was recorded at the Hayden Planetarium on December 5, 2011.
