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.
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.
Because if everything we can see is moving away from us, and the further away the faster it's going, if you extrapolate back in time you realize that at some point everything must have been very close together. That's more or less the core of the Big Bang theory. answer2: The Big bang is a bust if there is no expansion , motion! Red shift is interpreted as the motion, thus the Big Bang is possible. However, the red shift is misinterpreted. Hubble himself, did not accept the red shift as recession, rather Hubble called the red shift, "a hitherto unrecognized principle of Nature". The red shift is the indicator of the centrifugal force, associated with the "Dark Energy", the vector energy Ev=mcV. Properly interpreted, the red shift indicates no Expansion, no Big Bang.
All modern models based on science that are worth their salt would be. The only major theory I know about the origin of the universe is the Big Bang Theory, which is supported by Red Shift observations. Galaxies we can observe are all moving away (we know this due to Red Shift) from a central point, believed to be the epicenter of the Big Bang.
Doppler shift shows that galaxies are moving away from each other at rates that depend on how far apart they are. According to the Big Bang Theory, the universe began with an enormous explosion. Then, the entire universe began to expand everywhere at the same time.The doppler shift shows that galaxies are moving away from each other at rates that depend on how far apart they are.
The Big Bang theory predicts an expanding universe. The red shift, being the Doppler effect of light when something is receding from you, confirms this because when looking at galaxies the light emitted from them is red shifted. The farther away galaxies have a higher red shift, confirming that all galaxies are moving away from each other, not just the Milky Way (i.e. the universe is expanding).
the big bang theory is a cosmological model wich states that how was universe created and why it is expanding.
The big bang theory is a cosmological model. Is this really the question you are trying to ask?

I presume the question refers to the "redshift" of distant galaxies. Actually it is the other way around - i.e. the Doppler redshift helps to support and explain the Big Bang Theory. This "redshift" is called the "cosmological redshift". Strictly speaking, it's not the Doppler effect.
there was never a big bang GOD made it of course
The Big Bang is the theory that was developed to describe the origins of the universe.
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.
As far as I understand, the Big Bang theory is not a challenge to the cosmological argument at all. The cosmological argument states that there must have been a beginning to the universe, which is confirmed by modern science. The cosmological argument further is often held to indicate that that beginning must have been an intelligent agent, which is neither confirmed nor denied by cosmology.
The red shift doesn't just indicate that there is evidence for the Big Bang theory: the Hubble red shift is evidence supporting the Big Bang theory.
Redshift; the generally accepted explanation for the redshift of distant galaxies is that it is cosmological redshift, caused by the expansion of the Universe. This is somewhat related to the idea of the Doppler effect.
All matter. All the matter that exists emerged from the primordial cosmological state that we call the 'Big Bang'.
