WebLight spectrums produced from distant galaxies are red-shifted more than nearby galaxies. This shows that the greater the distance to the galaxy, the greater the redshift. This means that the further away a galaxy is, the faster it is moving away from the Earth. These observations imply that the universe is expanding and therefore support the ...

The term can be understood literally - the wavelength of the light is stretched, so the light is seen as 'shifted' towards the red part of the spectrum. Something similar happens to sound waves when a source of sound moves ...
