The Movement of Galaxies in Space
Clip: Episode 4 | 4m 33sVideo has Closed Captions
A track race demo explains how the galaxies furthest from Earth move fastest.
The volunteers must organize a special race mimicking the movement of galaxies in space. They must arrange the "galaxies" in order to start the race, but they don’t all start form the same point. They are surprised to see that some of the galaxies walk and some run very fast. This demonstrates that the galaxies furthest away from Earth are also the ones traveling the fastest.
