Red shift is the irrefutable fact that the light from all distant galaxies (ie, those outside our Local Cluster) has a longer wavelength (ie, is shifted to the red spectrum) than it would if the galaxy were close to us. It is also irrefutable that the amount of red-shift is dependent on the distance between us and the galaxy. In conjunction with other irrefutable facts, the only explanation is that the distances between all galaxies -- indeed, all lengths -- are growing greater with time.

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.

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.


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..

How does red shift support the steady state theory?

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.


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.


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 important is red shift to your understanding of the universe?

Redshift happen when light seen from the object that is moving away is proportionally increased in wavelength (i.e shifted toward the red end of the spectrum) . Thus red shifts relates that further the galaxy ( outside or inside the local cluster ) more it is red-shifted (i.e greater the wavelength ) than the closer galaxy and it explain the expansion of our universe , further the galaxy more fast it moves away from us .


The discovery of a red shift in the spectra of galaxies provided evidence that the universe is?
