There is an observable increase in the ( wavelength, nearby, distant, slower, faster, towards, away from, greater, smaller, red-shift, blue-shift, frequency ) of light from most ( distant, nearby, slower, faster, towards, away from, greater, smaller, red-shift, blue-shift, wavelength, frequency ) galaxies. The further away the galaxies are, the ( greater, wavelength, nearby, distant, slower, faster, towards, away from, smaller, red-shift, blue-shift, frequency ) the observed increase in ( wavelength, nearby, distant, slower, faster, towards, away from, greater, smaller, red-shift, blue-shift, frequency ), and so the ( faster, slower, nearby, distant, towards, away from, greater, smaller, red-shift, blue-shift, wavelength, frequency ) they are moving away from us. This effect is called ( red-shift, blue-shift, nearby, distant, slower, faster, towards, away from, greater, smaller, wavelength, frequency ) because the wavelengths are stretched towards the red end of the spectrum.
