In this episode, Nick shrinks Dave to the size of a bacterium and sends him into the savage battlefield of the human immune system, a breathtaking biological enterprise that's second in complexity only to the human brain. Then, Dave takes us to the very edge of the universe, where something unknown lurks beyond observable space, emitting such an immense gravitational pull that this mysterious celestial body is believed to be the largest, densest object in the universe.
