What's driving the expansion of the universe, and will it ever stop? Take a trip to the dark side in a video full of surprising facts and twists about our view of what lies beyond. Junior cosmologists learn about the invisible energy of space, called dark matter, and its role in expanding space. The narrator also discusses methods for measuring the expansion and the eventuality that our skies may grow dark as the observable universe moves farther away.
