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.

What creates the phenomeon known as red shift?
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.

red shift
When was The Red Shift created?
The Red Shift was created in 2005-06.
What is the opposite of the red shift?
The opposite of the red shift is the purple shift.
What is ctrl-shift-spacebar?
It creates a 'hard space'
Can a red shift and a blue shift exist on the same object at the same time?
No, red shift and blue shift are opposite phenomena caused by the Doppler effect. Red shift occurs when an object is moving away from the observer, while blue shift occurs when an object is moving towards the observer. It is not possible for an object to exhibit both red shift and blue shift simultaneously.
What is the shift in the light of a galaxy toward the red wavelength called?
This phenomenon is called red shift.
What is the red shift of hydrogen?
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).
What does red shift show?
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.
How does red-shift support the steady state theory?
Red shift does not support the steady state theory.
What does shift enter do in Internet Explorer?
Creates a new line in textarea..
How does blue and red shift help us understand the changes of the universe?
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..
