Known Universe S03 E08 End of the World

The world didn't end on 5/21/11 as some feared, but someday it will, and not just on Earth, but for asteroids, comets, moons, planets, stars and everything in our Known Universe. To demonstrate this complex cycle of life and death, scientist David Kaplan watches the destruction of a 16-story building shattering the structure while creating new matter and debris. We'll also see how a wildfire compares to the ignition of a supernova deep in space, and step inside a black hole simulator.
