This redshift is a strong indication that the Universe is expanding. The only reasonable explanation of this redshift is the Doppler effect, and this means that the galaxies are moving away from us. The greater their distance from us, the faster they move away.

Based on the observed red shifts in the spectral lines of distant galaxies?
Astronomers conclude that the universe is expanding, because wavelengths are increasing.
What evidence do we have to prove that galaxies rotate?
Doppler red shifts and blue shifts of light from the stars in the galaxies.
Are Large red shifts within galaxies or between them?
Between them.
How does red shift differ between galaxies close to us and ones which are further away?
Generally, the galaxies that are further away will have the larger red shifts.
What was one form of evidence used to support the Big Bang theory?
The observation that red shifts of distant galaxies gets greater the further away the galaxies are.
What ''shifts'' when you have a Doppler shift in starlight?
What shifts is the frequencies of the light. This can be observed by certain lines in the spectrum, which have very specific positions (frequencies).
Why scientist don't expect to find galaxies that have large blue shifts?
This should be because of the fact that the Universe is expanding. You see a blueshift when objects move closer to you. Other than super distant galaxies, most galaxies will not measure to be a blueshift due to the fact that the Universe is expanding and accelerating.
How did Edwin Hubble determine that the Great Galaxy in Andromeda is located beyond our galaxy?
That became clear once the telescopes were powerful enough to distinguish individual stars in the galaxies. Before that, they were seen only as "nebulae" (cloud-like objects), and it wasn't clear whether M31 (for example) was part of our own galaxy. M31 is also known as the Andromeda Galaxy.
Do all galaxies outside local group have red shifts?
Yes. Also, the size of the red-shift for all distant galaxies is directly proportional to their distance from us. This means that the space between us and all distant galaxies is expanding. Thus, Einstein's (initial) view that our Universe has been eternally stable in the location of matter must be false. No surprise that he referred to his early view as his "greatest blunder."
When examining the red shift of galaxies outside your own every galazy to be moving away the observer this observation supports the big bang theory because it indicates that?
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.
Major contributions to theory of evolutions?
Genetic recombination and drastic evolutionary shifts have been observed in bacteria in many laboratory experiments. There really isn't much "theory" to it anymore.
Why will the 2002 Kia Spectra not go into park but only reverse?
you probably have a bad transmission, or try to drain it and then fill it with some stuff called prolong. once you fill it put your e brake on and leave it in drive for a half hour at idle, after that see if it shifts for you.
