Cosmological redshift is the shift in stellar spectrum due the space within our Universe expanding since the time of the Big Bang. It is isotropic, which could only happen if the Universe were expanding -- if it was spinning apart, the red shift would be different in different directions.
The age of our Universe, as measured by (1) the inverse of the Hubble Constant, (2) the ratio of long-lived isotopes, and (3) the age of the oldest known stars; is all consistent with each other. In addition, "old" galaxies are seen close to us but not far from us -- consistent with a Universe that has a definite beginning.
This interpretation is incorrect in that the universe is not expanding. Hubble data is used as the basis for this interpretation, even though Hubble did not concur or support expansion as the cause of the redshift.
The so-called cosmological redshift is a measure of the centrifugal attraction on the body.
The redshift is basically the ratio of v/c where v is the gravitational velocity of the body and c is the speed of light and v/c=cos(beta) where beta is the angle of the velocity of the body compared to the gravitational radial direction.
This is an unknown principle of nature in that Newton and Einstein did not consider the vector energy in their theories. Energy is a quaternion quantity.
Newton and Einstein only considered the scalar energy Es= -GmM/r and did not consider the vector energy mcV, for a total quaternion energy E= -GmM/r + mcV.
This vector energy is the source of the centrifugal force and makes irrelevant Einstein's "Cosmological Constant" and today's so-called "Dark Energy".
Physics still has not recognized this and clings to the expanding Universe. The Universe is not expanding and the Cosmological redshift is the measure of equilibrium between the centripetal (center seeking) gravitational force and the centrifugal (center fleeing) vector force.

∙ 10y agoThe red shift is used to measure how fast the galaxies are moving away from us. The greater the red shift, the faster the galaxies are moving away from us.

How is distance measured at cosmological scales?
Distance at galactic scales is usually measured in terms of lightyears. Distance at cosmological scales may also be put in terms of Hubble red-shift factors.
How does cosmological red shift support the big bang theory?
Jesuit priest George LeMaitre first proposed the idea that the space of our Universe is expanding, and has been doing so since (his words) "the day with no yesterday." If his idea is correct, then we would see all galaxies outside our Local Group as red shifted, and the size of that red shift would be proportional to the distance between us and those distant galaxies. This undeniable fact about our Universe -- called the Cosmological (or Hubble) Red Shift -- is exactly what we do see.
What is the difference between the cosmological and Doppler red shift?
Red shift is the change in the spectra of galaxies towards being more red than we would expect them to be. Doppler Shift results from galaxies being in motion away from us. Thus, the large Andromeda Galaxy has a blue shift, because it and our Milky Way Galaxy are being pulled towards each other due to gravity. Cosmological Shift results from the space between us and other galaxies growing larger over time, even though neither they nor our Milky Way Galaxy are in motion relative to one another.
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 does it look like when you reach the end of the universe?
There probably is no end to the Universe. A finite end is based on the cosmological red shift being a Doppler effect on photon frequency. However there is no independent verification of this. I suspect that the red shift is actually from an interaction with masses passed in space. To see a discussion of this access http://www.geocities.com/isoptera.geo/redaw.html
What is Doppler red shift?
Its part of science! Edit : In astronomy, the Doppler effect is the change in wavelength of light caused by movement of a light source such as a star or a whole galaxy. The term "red shift" refers to the increase in the light's wavelength from the blue to the red end of the spectrum. This happens when a light source is moving away from us. I don't want to over complicate things, but there is a similar thing called the "cosmological red shift ", but that's caused by the expansion of space itself.
How many galaxies are approaching milky way galaxy and how many are moving away related to the cosmological red shift?
Most galaxies are moving away from us. Only a few galaxies, which are nearby, are moving towards us.
What is the opposite of the red shift?
The opposite of the red shift is the purple shift.
How red shift connect with universe expanding?
The expansion of the Universe results in the light from faraway galaxies being redshifted. This is called the "cosmological redshift"; it can be compared with the Doppler effect (which also causes a redshift), but the details are somewhat difference.It is an observed fact that most galaxies are redshifted; the explanation that seems most reasonable is that it is caused by the cosmological redshift. This means that space itself is expanding.
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.
