The red shift of galaxies suggests that the universe is expanding in all directions. As the space-time volume between galaxies increases, they seem to move away in all directions and the wavelength of light received is "stretched" meaning a shift in frequency towards the red end of the spectrum.
This forms part of Hubble's law included in Edwin Hubble's paper in 1929
Yes, but it could mean something else. How much energy does the light lose when climbing out of a gravity hole (a large star, for a large distance).
Expanding Or that the light is exiting a gravity hole (star).
... expanding. The redshift is attributed to the Doppler effect, meaning that those galaxies are receding, or getting away, from us.
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.
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.

hi i am minakshi and the answer is that when examining the red shifts of galaxies outside our own galaxies to be moving away the observer this observation supports the big bang theory because indicates that every matter of the universe was consentrated at one place and after big bang the universe is expanding.
The Red Shift or Doppler effect

NoRed shift is the Doppler effect as it applies to the light from receding galaxies and stars.As the name suggests, "irregular" galaxies have no specific form, and so the group contains a very diverse selection of objects.
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.
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.
