This clip explores the origins of the universe and describes the leading theory, the Big Bang, with supporting visuals.

Stephen Hawking tasks a team of volunteers with replicating the Big Bang on in a hockey rink. The volunteers decide to stand next to each other and inflate balloons to simulate an "explosion." They enlist the help of a professional hockey team since they have trouble staying on the ice and need more people to create a better representation of the Big Bang.

This clip explores the origins of the universe and the focus of cosmologists. It describes the leading theory, the Big Bang theory, and discusses how physicists study the universe using particle colliders.

This clip explores the leading theory about the origins of the universe, the Big Bang theory. It shares evidence for this theory, notes that the universe is exponentially growing larger, and describes the Big Bang theory in detail.

Participants in an experiment attempt to understand how runners in an indoor track relates to the universe. They assign each runner a race bib, which contains a galaxy name and its distance from Earth. The runners race at the speeds appropriate to their assigned galaxy: the farther away they are from Earth, the faster they move.
