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.
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.
