Galactic Redshift
After the emergeence of Big Bang theory a lot of study have been concluded to give a validity of Big Bang theory. Galactic redshift is an important evidence of validity of Big Bang theory.
Dopplar effect is somewhat similar with redshift. Doppler states that if a sound originating from a source will be sound of less wavelength to the spectator if the sound source move toward the spectators. Oppositely, If the soundsource move away from the spectator the wavelength will feel longer of the sound wave by the spectator.
As same as, in terms of light same thing will happen.
In generally something light if move away from the observer, the observer will see the light with increased wavelength than the emitting wavelength. The colour will feel by observer will tends to at the red end. This phenomenon is termed as redshift. This is similar to the Doppler effect. If the sound source move away from the spectators, the spectator will fell the sound with increased wavelength than the originating wavelength.
As same as if the light source get forward toward the observer the observer will feel the light as decreased wavelength than the originating wavelength. Hence the colour feel by observer will tend to blue end. This phenomenon is termed as blue shift.
Redshift conception is a great evidence of Big Bang theory. Big Bang theory suggests that universe is continuously expanding from a singular point. Everything is getting distance from each other. If that is true then the redshift will be true. As same as if redshift happens exactly, the acceptance of big bang theory increases.
There happens three types of redshift in our universe. One is redshift with the expansion of universe. Second is the redshift in galaxies due to getting distance of one galaxy to other galaxy. Another is the gravitational redshif.
Though in stars and galaxies the occurance of redshift can easily explain on the basis that from our earth we see stars and galaxies as red. From our earth someone will see the stars a far distance away as red. It will be as same any obserserver if exist on that star or galaxy, will see our galaxy as red. Because according to Big Bang theory each of these are getting distance from each other.
What means Galactic redshift?
The word redshift in generally we can guess something colour changing or shifting to the red. Galactic redshift means the colour of light emitted by galaxy tends to red end. But more accurately to say that the colour of galaxy is tends to red by an observer. The galactic redshift is more important for physicists and astronomers. Because it is an evidence of big bang theorem and Hubbles theorey.
Doppler effect and redshift relationship
Dopplar effect is somewhat similar with redshift. Doppler states that if a sound originating from a source will be sound of less wavelength to the spectator if the sound source move toward the spectators. Oppositely, If the soundsource move away from the spectator the wavelength will feel longer of the sound wave by the spectator.

Redshift supports Big Bang
Redshift conception is a great evidence of Big Bang theory. Big Bang theory suggests that universe is continuously expanding from a singular point. Everything is getting distance from each other. If that is true then the redshift will be true. As same as if redshift happens exactly, the acceptance of big bang theory increases.
Types of redshift in universe
