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.
Actually, it wasn't the Doppler-effect that lead to the Big Bang theory, but the red-shift of remote galaxies. Although it was initially thought that this red-shift might be caused by a Doppler-effect, it is now understood that this red-shift is caused by the metric expansion of space itself.
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.
You might say that. But it's probably closer to the truth to say that it worked in exactly the opposite way . . . The Big Bang theory is an attempt to explain the shift toward red in the spectra of all distant galaxies, along with many additional observational facts in Astronomy, Physics, and Cosmology.
The Doppler effect and background cosmic radiation are the big ones.
For example, it can clearly be seen - by the Doppler effect - that the Universe is expanding.
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.
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.
The Big Bang Model!
No, it's the other way round. The Big Bang is responsible for the redshift.
In "The Big Bang Theory," Sheldon explains the Doppler effect by using the example of a train whistle changing pitch as it approaches and then passes by. This change in pitch is due to the compression and expansion of sound waves as the train moves relative to the observer.
