The use of red shift measurements depends on luminosity and the interpretation of the observer. While the spectrum of light must be narrowed down to a single source, one searches for features in the spectrum such as absorption lines, emission lines, or other variations in light intensity. If found, these features can be compared with known features in the spectrum of various chemical compounds found in experiments where that compound is located on earth. Therefore redshifts cannot be calculated by looking at unidentified features whose rest-frame frequency is not known.

Are there any weaknesses or gaps in the Big Bang Theory that are being considered?
The big bang is based solely on the cosmological red shift, whereby the light from distant stars has lost energy, is assumed to be a Doppler red shift. However there is no direct evidence that that kind of a shift is actually what happens. There are also several "tired light" hypotheses.
What is the opposite of the red shift?
The opposite of the red shift is the purple shift.
When was The Red Shift created?
The Red Shift was created in 2005-06.
What determines galaxy motion and distance?
One of the most reliable methods employed presently is using Hubbles Laws and Constant, utilizing the red shift. RED SHIFT A+LS (:
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.
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..
Who discovered the red shift?
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.

How are Doppler blue and red shift different?
A blue shift is observed in the spectrum from an object approaching the observer whereas a red shift is observed for a receding object.
