If you think that scientists believe that the cosmological redshift is due to the Doppler Effect, then you are very misinformed. :nono:
No, I'm not! This has to have been the latest of your lies!
What is it with you? Can you just not help saying things even when you know what you're saying is obviously false and easily verified as such?
The very first thing you see when you google "What is redshift"...
red·shift
ˈredˈSHift/
nounAstronomy
noun: red shift; plural noun: red shifts; noun: redshift; plural noun: redshifts; noun: red-shift; plural noun: red-shifts
the displacement of spectral lines toward longer wavelengths (the red end of the spectrum) in radiation from distant galaxies and celestial objects. This is interpreted as a Doppler shift that is proportional to the velocity of recession and thus to distance.

Redshift and blueshift describe how light changes as objects in space (such as stars or galaxies) move closer or farther away from us. The concept is key to charting the universe's expansion.
Visible light is a spectrum of colors, which is clear to anyone who has looked at a rainbow. When an object moves away from us, the light is shifted to the red end of the spectrum, as its wavelengths get longer. If an object moves closer, the light moves to the blue end of the spectrum, as its wavelengths get shorter.
To think of this more clearly, the European Space Agency suggests, imagine yourself listening to a police siren as the car rushes by you on the road.
"Everyone has heard the increased pitch of an approaching police siren and the sharp decrease in pitch as the siren passes by and recedes. The effect arises because the sound waves arrive at the listener's ear closer together as the source approaches, and further apart as it recedes," ESA wrote.
Sound and light
This sound effect was first described by Christian Andreas Doppler and is called the Doppler effect.

What is a redshift? It’s often compared to the way a police officer catches you when you’re speeding. But, in the case of astronomy, these answers all come from our ability to detect miniscule changes in the color of light.
Police and astronomers both rely on a principle called the Doppler shift.
From Wikipedia...
In physics, redshift happens when light or other electromagnetic radiation from an object is increased in wavelength, or shifted to the red end of the spectrum. In general, whether or not the radiation is within the visible spectrum, "redder" means an increase in wavelength – equivalent to a lower frequency and a lower photon energy, in accordance with, respectively, the wave and quantum theories of light.
Some redshifts are an example of the Doppler effect, familiar in the change of apparent pitches of sirens and frequency of the sound waves emitted by speeding vehicles. A redshift occurs whenever a light source moves away from an observer. A special instance of this is the cosmological redshift, which is due to the expansion of the universe, and sufficiently distant light sources (generally more than a few million light years away) show redshift corresponding to the rate of increase in their distance from Earth. Finally, gravitational redshift is a relativistic effect observed in electromagnetic radiation moving out of gravitational fields. Conversely, a decrease in wavelength is called blueshift and is generally seen when a light-emitting object moves toward an observer or when electromagnetic radiation moves into a gravitational field. However, redshift is a more common term and sometimes blueshift is referred to as negative redshift.
Knowledge of redshifts and blueshifts has been applied to develop several terrestrial technologies such as Doppler radar and radar guns. Redshifts are also seen in the spectroscopic observations of astronomical objects. Its value is represented by the letter z.
That is how science progresses. Even EU theory seems to have progressed in the same way.
That is how establishment scientists have progressed for the last hundred years but that is NOT how the scientific method describes how science should progress. Observation is supposed to be the beginning of the process not the middle or end of it. Today, science begins with mathematical models and then goes looking for evidence to support (i.e. "confirm") those models. If observation contradicts the models then they tweak the model in an ad hoc fashion. That is no science! That isn't even sound reason! When any creationist makes this sort of error, you so quick to pounce that you barely have time to understand the argument before you've half way down their throat!
That's an hour long video about Arp's deductions of intrinsic redshifts based on a tiny sample of quasars, an idea that has been shown to be wrong if you use the very large scale surveys over the last two decades, and direct observations of some of the quasar's own host galaxies that confirm their cosmologically distant nature. And the video is an hour long - too long for a forum discussion. If their is evidence inn there about electric fields, please give me the time at which it is demonstrated.
Tell that to Carl Sagan...
There is, nevertheless, a nagging suspicion, among some astronomers, that all may not be right with the deduction, from the redshift of galaxies via the Doppler effect, that the universe is expanding. The astronomer Halton Arp has found enigmatic and disturbing cases where galaxies and a quasar or a pair of galaxies that are in apparent physical association have very different redshifts." - Carl Sagan
Besides, you asked me a question and I answered it. If you don't want to watch the video then take what information the title of the video gives you and look up something else. And it isn't merely about Halton Arp, the video is Halton Arp himself discussing the issue of red-shift.
Also, if anyone, Arp or whomever, found even one single example of two galaxies with significantly different red-shifts that were physically connected, it would falsify red-shift theory. It WOULD falsify it! He found a lot more than one and mainstream cosmology hasn't a clue how to explain what is clearly observed and verified to exist in the real universe.
I have a question that you almost certainly will not answer. If there is something other than relative motion causing red-shift, what portion of big-bang cosmology survives? Asked another way, what, if not "red-shift of galaxies via the Doppler effect", as Carl Sagan put it, is the foundational premise of the big-bang theory?
