Red Shifting happens when an object is moving away from us. The red shifting we observe when looking at distant galaxies over time tells us that they are moving away from us; the Universe is expanding.
Blue shifting would happen in the opposite scenario. You can see blue shifting if you looked at the outer perimeter of any Galaxy as since they are constantly spinning, one side will always be heading towards you...to explain this further:
Draw a dot on the outer-edge of the frisbee. Now have the frisbee spinning in front of you counter-clockwise. For each rotation, the dot is moving towards you. That will be a blue shift. Now since the Universe is expanding, the frisbee itself is also movign away from you -- that is a red shift.

and the farther away from us it already is, the faster it's moving away from us.
If you think about that for a while, it seems to say that the entire universe is
expanding, and we happen to be at the center of it.

Answer:
Hubble said the red shift is an "hitherto unrecognized principle of the universe."
The redshift tells us that the Universe is in Continuity Condition, Stationary orbit, Non-Expanding.
The red shift tells us there is balance between the scalar (centripetal vs centrifugal) forces , thus no change in the orbit.
The red shift is Beta (v/c), the Fine Structure Constant for Matter, like Alpha (v/c), the Fine Structure Constant is for Charge. The redshift is the inverse refraction coefficient, v/c = 1/n.
Force F=mv2/r = mv2/ct = mvv/ct= m(v/t)(v/c) = ma(v/c). v/c is the red shift and the Fine Structure Constant for matter!
The red shift for earth is 30k/c = .0001 or angle 89degrees 59 minutes and 39 seconds. The red shift does not indicate expansion of the Universe. The redshift indicates that the orbit is stationary, Continuity Condition,
vp/r = cDEL.P= cp/r cos(P) thus v/c = cos(P). The angle is such that the centrifugal force balances the centripetal force vp/r.
The centrifugal force is the Divergence of the Momentum energy cP, the so-called Dark Energy. The vector energy(Dark Energy) is the energy associated with the the Momentum mV, thus cmV= cP. Physicists are ignoring the Momentum of mass m and its assoicated vector energy.
The Total Gravitational Energy is W =-mGM/r + cP.
Oh, yes, the red shift indicates that light is escaping from a gravity hole (star).

∙ 9y agoThe red-shift of a star can tell us two things:
- For nearby stars, the red-shift tells us how fast the star is moving away from us. In this case, the red-shift is caused by the Doppler effect, rather than metric expansion.
- For very remote stars and galaxies, the red-shift component caused by metric expansion outweighs the red-shift caused by the object's motion relative to the metric. In this case, the red-shift can be used to gauge both the pseudo-speed of the object (the speed with which the space in between here and there is expanding) and the distance to the object.
Answer2:
The red-shift of a star can tell us how strong the star is attracted to its gravitational center. The larger the red-shift, the closer the star is to its gravitational center.
The red-shift also indicates the star is balanced; centripetal equal centrifugal force.

Explain why some stars in the milky way galaxy have a blue shift Doppler effect and other stars in the milky way have a red shift Doppler?
A blue-shift means an object is moving towards us, a red-shift means it is moving away from us. Blue-shift and red-shift are changes in frequency of the light we receive, due to the relative movement. This is called the Doppler effect.
Does the colour of a galaxy reflect its distance away from the earth?
No, however, we can determine whether a galaxy is moving towards or away from us, by looking at the shift in its spectrographic analysis. There are "red shifts" and "blue shifts" in spectrographic results. "Blue shifts" indicate that a galaxy is moving towards us, because the wavelength of the light emitted by the galaxy is compressed, causing it to shift to the blue end of the colour spectrum. "Red shifts" indicate that a galaxy is moving away from us, because the wavelength of the light emitted by the galaxy is being stretched towards the red end of the colour spectrum.
What are there flag colors of France?
Blue, white, and red. Blue, white, and red.

What color was the French flag in the 1800s?
Blue,white,and red Blue,white,and red
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.
How does blue and red shift help us understand the changes of the universe?
Red shift has confirmed the expansion of universe. Both red and blue shift at the edges of the sun has confirmed the spin of sun..
Observation of the shift of a stars spectrum toward the red or blue enables us to determine the stars?
The star's velocity (away from us, or towards us).
Can a red shift and a blue shift exist on the same object at the same time?
No.
How is the red shift different than the blue shift?
Radiation from a source moving away from the observer is red-shifted. Radiation from a source moving towards the observer is blue-shifted.
Why are red shift and blue shift effects useful in the study of the universe?
Red shift means that other objects in the universe are moving away and blue shift means they are moving toward you. This helps to tell where these objects came from, and this knowledge helps predict where they are going to.
What colors do you mix for burnt orange?
True red and true yellow will give you orange, varying the amount of red will determine the colour of orange... start with a redder orange and add a bit of blue, this will bring the orange toward the brown tones, varying the amount of blue will adjust your colour until you have the one you want.
How does a red shift from a blue shift?
A red shift shows us that a object is moving away, while a blue shift shows us an object is moving toward us. Light that has been 'red shifted' has a longer wavelength when it reaches our eyes/telescopes/etc. than it had when it left the object. Light that has been 'blue shifted' now has a shorter wavelength. The reason stretching the wavelength is known as 'red shifting' is that, in the visible spectrum, red light has the longest wavelength. Blue light has a much shorter wavelength than red so when the wavelength is compressed, we call it blue shifting.
How do red shifts were used by cosmologists to determine that the universe is expanding?
A Galaxy's red-shift can be used to determine how fast it is travelling away from you. The opposite is "blue-shift" which is what happens when the Galaxy is travelling towards you.The first astronomers, such as Edwin Hubble, to analyse the light coming from distant galaxies discovered that almost all of them were red-shifted, indicating that they were almost all heading away from us. This was the first indication that the universe was expanding.
What did hubble discover as a result of studying red shift of distant galaxies?
that the universe was in 1904 expanding. this was due to the lack of blue shift, therefor it can be deduced that the red shift in orrcuring within the galaxy.

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."
