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.
The universe is expanding, as a result both of the Big Bang (some thirteen and a half billion years ago) and also what appears to be pressure exerted by what is known as dark energy (which is to say, some kind of energy which we have a great deal of difficulty in directly observing). Because of this expansion, distant objects (beyond our local galactic cluster) are moving away from us, and the more distant they are, the faster they are moving away. This receding motion creates a red shift (that is, a shift to longer wavelengths) in their spectra, known as a Doppler shift. If they were approaching rather than receding, the shift would be toward the blue (shorter wavelengths).
The Red Shift was created in 2005-06.
Objects moving toward you will have a blue shift in their spectrum and objects moving away from you will have a red shift in their spectrum. This is known as a doppler shift.
One of the most reliable methods employed presently is using Hubbles Laws and Constant, utilizing the red shift. RED SHIFT A+LS (:
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..
In 1848, Hippolyte Fizeau first noted a red shift in stars. In 1912, Vesto Slipher first noted a large red shift in nebulae. In 1929, Edwin Hubble published his findings that the size of galaxy's red shift was proportional to its distance from our Earth.
