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
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.
expanding
Redshift in the universe occurs as objects move away from one another, expanding the universe. This indicates that the universe is still expanding, consistent with the Big Bang theory. The rate of this expansion, known as the Hubble constant, provides insight into the age and future of the universe.

universe is expanding at an accelerated rate.
The universe expanding in all directions.

Red shift supports the theory of the expanding universe proposed by Edwin Hubble. The observed red shift in the spectra of distant galaxies indicates that they are moving away from us, providing evidence for the idea that the universe is continuously growing and expanding.

One of the best indications that the universe is expanding is the redshift of light from distant galaxies, which shows that they are moving away from us. Another indication is the cosmic microwave background radiation, which is consistent with an expanding universe. Additionally, observations of the distribution of galaxies and the large-scale structure of the universe support the idea of expansion.

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.
Red shift supports the steady state theory in that the red shift indicates the Continuity Condition. Steady State means Conservation of Energy and does not require an expanding universe. It is the misunderstanding of red shift that adds the requirement of an expanding universe and the need for continuous creation.Hubble saw red shift as a "hitherto unrecognized principle of nature", not an expansion of the universe. less prudent physicists have misunderstood red shift. Red shift is an indicator of "continuity condition" and the result of centrifugal force balancing gravitational centripetal force.Steady State is the proper term for Conservation of Energy or Homeostasis, which seems to characterize the universe. "Steady State Theory" without expansion is well supported by red shift.The proper Theory of Gravity, E = -mu/r + mcV, accounts for 'dark Energy and red shift" and a finite universe.
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.
