Is That Star Really There?
Alice wonders if a star in the sky is really there. Alice and Bob explain that the light we are seeing now is how the star looked many years ago. This leads them on to the idea that if we look out far enough into the Universe, then we may be able to see back towards the beginning of the Universe.
This clip could provide a lead in to topics such as the speed of light, the expansion of the Universe and the Big Bang.
