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.
A group of participants attempts to understand the purpose of the machine and the magnets given to them. After they put the magnets in the machine and turn it on, they notice that the magnets start to form complex structures on their own. The magnets symbolize atoms, and the experience suggests that compounds can form on their own over time, given a constant input of energy.
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.
