red shift

or red·shift (rĕd′shĭft′)
An increase in the wavelength of radiation emitted by a receding celestial object as a consequence of the Doppler effect.

[From the fact that the longer wavelengths of light are at the red end of the visible spectrum.]

(Astronomy) a shift in the lines of the spectrum of an astronomical object towards a longer wavelength (the red end of an optical spectrum), relative to the wavelength of these lines in the terrestrial spectrum, usually as a result of the Doppler effect caused by the recession of the object. Compare: blueshift

With radio frequency data showing redshift quantization much more clearly than his own optical frequency data did, readily determined that 21-cm radio work was the way to go in pursuing his theories.
Due to the redshift inherent in the Hubble constant, the farther distant stellar bodies are from Earth the faster they appear to be moving away from us, until at the limits of our observations, these bodies are receding at a velocity close to that of light itself.

The determination of age of these black holes is based on how far they are, which in turn is estimated using redshift - the lengthening of the wavelength of light, caused by Doppler effect, in an expanding universe.
Astronomers have found a humdinger of a galaxy dubbed CN-zll, which dwells in a uni verse just 400 million years old (in astrospeak, at a redshift, z, of 11.1, which refers to how much the universe's expansion has shifted the galaxy's spectra).
