Show for April 17, 2011. The Dark Universe.
Ordinary matter is so 20th century. In recent decades, scientists have found that the vast bulk of the universe (95-96 percent) consists of some as-yet-unidentified thingums known as “dark matter” and “dark energy.” Astrophysicist Rocky Kolb (pronouned “Kobb,” BTW) explains what we know and don’t know about these mystery ingredients. Then science writer Richard Panek describes the sometimes bumpy road to their discovery.
