Drag Racing to Explore the Doppler Effect
Clip: Episode 4 | 3m 16sVideo has Closed Captions
Hubble’s theory explored with a Doppler effect drag racing challenge.
Stephen Hawking and Neil Turok introduce us to Einstein’s idea of a static universe. The volunteers arrive at a drag strip with an electric car ready to go. They must use the sound of the siren, a microphone and laptop to determine the speed and direction of the car. How fast will the car go and what can it tell them about our universe?
