How is the red shift and blue shift related to the big bang theory?

If a galaxy is red-shifted, the distance us and that galaxy is increasing. If it is blue-shifted, the distance is decreasing.
If the galaxies in our Universe were random in their velocities relative to us, about half of them would be red-shifted and about half would be blue-shifted; and the distance between us and another galaxy would have no effect on the ratio.
But that's not what we see. All galaxies outside our Local Cluster are red-shifted, and we find that the greater the distance between us and a galaxy, the greater the red shift. That the size of the red shift depends on the distance is isotopic in all directions, meaning the distance between us and all other galaxies is increasing at the same ratio based on distance from us.
The BEST explanation of this undeniable fact is that, at some time, space itself (NOT the matter, but space) began to expand, taking matter along for the "ride." IF that hypothesis is correct, we would observe, not only red-shift in all distant galaxies, but other effects. We do indeed see the latter, and exactly as predicted by the Big Bang.

What is red shift and blue shift why are these effects useful in the study of the universe?
Red shift and blue shift refer to the shifting of light towards longer or shorter wavelengths, respectively. These effects occur due to the Doppler effect, where light sources moving away from us appear red shifted, and light sources moving towards us appear blue shifted. By measuring the extent of these shifts in the light from distant celestial objects, scientists can determine their motion and velocity, providing valuable information for studying the structure, expansion, and dynamics of the universe.
The big bang theory of the formation and expansion of the universe is supported by the observed?
There are several astronomical observations which support the Big Bang theory. First of all, the universe is expanding. That can be measured by observation of the Doppler shift in radiation emitted by various stars, galaxies, quasars, etc. Furthermore, the more distant any given astronomical object is, the more rapidly it is receding from us. This is consistent with the expected result of the Big Bang. Secondly, we have observed what is known as the cosmic background microwave radiation. The sky is filled with radiation, no matter in what direction you look, and it corresponds to the radiation that would be emitted by an object at a temperature of about 4 Kelvins. This is also consistent with the expected residue of the Big Bang, 13.8 billion years later (the universe has cooled off a lot, in that time). It is also possible to assess the chemical constituents of the universe, the quantities of hydrogen, helium, and other elements, which can be observed by spectrographic analysis, and again, the results are consistent with the Big Bang theory. Everything fits.
How does red shift lead to the big bang theory?
The red shift is a Doppler effect for visible light that implies an object is moving away from you. The blue shift is a Doppler effect for visible light that implies an object is moving towards you. Stars are distrbuted within galactic clusters. If a star is red-shifted, the distance between us and that galaxy is increasing. If it is blue-shifted, the distance between us and the galaxy is decreasing. All galaxies outside our local galactic cluster produce light that is red-shifted; and the greater the distance between us and these outside galaxies, the greater the red shift. That the size of the red shift depends on the distance is considered isotropic (or the same in all directions), meaning the distance between our local galactic cluster and all other galactic clusters is increasing at the same ratio based on distance from us. These distant galactic clusters, demonstrating red shift, are supportive evidence that these outside galaxies are moving further apart consistent with the Big Bang Theory. While the red shifted starlight is considered supportive evidence of an expanding universe, there are a few examples of blue shifted starlight within our Local galactic cluster. The Andromeda Galaxy is moving towards within the Milky Way galaxy, so when it is observed from Earth, its light is blue shifted. Any even within our own Milky Way galaxy, the Barnard Star is also moving towards Earth and appears to have a slight blue shift.

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.
Is the big bang theory supported by the blue violet shift?
Outside of our Local Group, no galaxy gives off light that exhibits a blue-shift. You most likely meant to say "red shift."

yes
Was that a blue jay on the big bang theory?

How is the blue shift related to the lifecycle of a star?
Not at all. "Blue shift" refers to a shift of features in the star's spectrum toward shorter wavelengths, for stars that are moving toward us. It has nothing at all to do with the composition or properties of the star itself.
Why hypsochromic shift is known as blue shift but not violet shift?
hypsochromic (blue) shift

What does a spectroscope have to with the big bang theory?
A spectroscope is an instrument that can be used to observe the frequency (or wavelength) of characteristic spectral lines to see how far the lines were shifted (red shift or blue shift) from their usual position. All galaxies outside our local galactic cluster produce light that is red-shifted; and the greater the distance between us and these outside galaxies, the greater the red shift. That the size of the red shift depends on the distance is considered isotropic (or the same in all directions), meaning the distance between our local galactic cluster and all other galactic clusters is increasing at the same ratio based on distance from us. These distant galactic clusters, demonstrating red shift, are supportive evidence that these outside galaxies are moving further apart consistent with the Big Bang Theory. Note: The core ideas of the Big Bang is that the Universe was filled homogeneously and isotropically with an incredibly high energy density and huge temperatures and pressures and was very rapidly expanding and cooling.
