nice question! actually when a wave approaches an observer the wave length of the wave decrease and as it move far from us its wavelength increase. it is quiet difficult to understand so use your imagination. as the wavelenght increase the spectrum will be shifted toward red spectrum and thus called red shift. when Edward Hubble studies spectrum of different star he noticed that because of some color spectrum were missing, other spectrum got shifted to ward red. it it moved toward red then that mean that wavelength was increasing and if wavelength increases then that means light moves away from us and thus he concluded that each and every star and galaxy was moving away from each other. so blue shift doesn't support big bang. inversely, blue shift support big crunch.
Outside of our Local Group, no galaxy gives off light that exhibits a blue-shift. You most likely meant to say "red shift."
If the Doppler shift indicated a blue-violet shift in the spectrum of distant galaxies, it would suggest that those galaxies are moving toward us rather than away, contradicting the current understanding of the expanding universe as described by the Big Bang theory. The Big Bang theory is supported by the observation of redshift in the light from distant galaxies, indicating they are receding due to the expansion of the universe. A blue shift would imply a contraction or a different cosmic scenario, prompting a reevaluation of fundamental cosmological principles. Thus, it would challenge the prevailing model of cosmic expansion.
No, it's the other way round. The Big Bang is responsible for the redshift.
The Big Bang Model!
yes
Hubble's red shift observation.
The red shift and the cosmic microwave background radiation was the evidence used to develop the big bang theory.
Red shift caused by the galaxies moving apart.
they both in outer space i really dont know.
Yes, a blue jay named "Morty" made a few appearances on the TV show "The Big Bang Theory" as a pet owned by Sheldon.
massive energy created matterTo get to the theory ... the red shift (and Hubble).If you're referring to how the big bang began, science has no answer.
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.
