On short distances (ie. within a few million lightyears), the redshift we see is the direct result of the Doppler effect. The Doppler effect causes light from receding sources to be less energetic, and thus red-shifted.
On distances exceeding that, redshift can be attributed to the metric expansion of the universe. In cosmological redshift, the shifting of frequencies is basically caused by the stretching of space the light is passing through, and the stretching of the light wave with it.
Two things can cause red-shift:- The rapid motion of an object away from the observer. This is known as the Doppler-effect.- Expansion of space between the object and the observer.
The opposite of the red shift is the purple shift.
It creates a 'hard space'
The Red Shift was created in 2005-06.
One of the most reliable methods employed presently is using Hubbles Laws and Constant, utilizing the red shift. RED SHIFT A+LS (:
plates in the earth move and shift, cracking the crust.

This phenomenon is called red shift.
The red shift depends on the relative motion of the emitting source and receiving detector. Hydrogen per se has no red shift. There is hydrogen with great red shift (in stars in galaxies far away that are moving rapidly away from us).
The red shift shows the velocity with which an object is moving away from the earth. The red shift of an object is correlated to its distance from the earth and so it is also a measure of the distance.
Red shift does not support the steady state theory.
Red shift has confirmed the expansion of universe. Both red and blue shift at the edges of the sun has confirmed the spin of sun..
