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

Why the red shift in light from distant galaxies indicate that the universe is expanding?
Red shift is observed in the spectrum of light from an object when it is moving away from the observer. Most astronomical objects display a red shift in their light. Also, the red shift is greater for objects which are further away. For this to happen - in all directions, the universe must be expanding.
How is the universe changing by red shift?
the universe is changing by red shift because when red shift occurs it means that galaxies and stars are moving away from us. this means that the whole universe must be expanding.
The discovery of a red shift in the spectra of galaxies provided evidence that the universe is?
expanding
What is important about Hubble discovery that there is a red shift in the spectra of galaxies?
that the universe is expanding(: YouR WelomE
Why does the red shift of galaxies provide evidence that the universe is expanding?
It means that the light from galaxies is losing energy. The only reasonable explanation for this is the cosmoligical redshift - that is, that the Universe is expanding.

What are the best indications that the universe is expanding?
A misunderstanding of red shift is the indicator is expanding. The correct understanding of red shift indicates the universe is in continuity, not expanding and is finite. RED SHIFT OF DISTANT GALAXIES.
What does red shift of the universe show is us?
universe is expanding at an accelerated rate.
What model of universe supported by red shift?
The universe expanding in all directions.

The redshift of light from distant galaxy provides evidence that the universe is?
The red shifts show the galaxies are under centripetal force and the red shift indicates the centrifugal force. This indicates that the universe is in continuity, the centripetal and centrifugal forces are in balance.
Observation of the red shift of galaxies suggest that the universe is what?
Expanding Or that the light is exiting a gravity hole (star).
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.
