 The strongest evidence for an expanding universe comes from the cosmological redshift. A redshift is a change in the spectrum of light as the distance between the source and the observer of the light increases. Such a redshift has been seen in the spectrum of light from distant stars. This means that the distance between those stars and the Earth is increasing, indicating an expanding universe
