Why scientist don't expect to find galaxies that have large blue shifts because of the big bang theory?
The observations show that the Universe is expanding. The farther a galaxy is away from us, the faster it moves away from us. Galaxies also have individual velocities, compared to their "local space", but those tend to be slow (in the order a few hundred kilometers per second), and at greater distances, the general expansion of the Universe dominates.

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.
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.
If all galaxies begin to show blue shifts what would this indicate about the fact of the universe?
If all galaxies began to show blue shifts, it would indicate that the universe is contracting rather than expanding. This could suggest a reversal in the overall dynamics of the universe, potentially leading to a scenario known as the "Big Crunch," where galaxies move closer together and ultimately collide. Such a shift would challenge current cosmological models that support the expansion of the universe, which is primarily evidenced by red shifts observed in distant galaxies. This fundamental change would have profound implications for our understanding of cosmic evolution and the fate of the universe.
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."
How did scientists belived that distant galaxies were rapidly moving away from the earth?
Scientists believed that distant galaxies were rapidly moving away from Earth primarily due to the observation of redshift in their light spectra. This phenomenon, known as the Doppler effect, indicated that as galaxies move away, their light shifts toward longer wavelengths (red). Edwin Hubble's observations in the 1920s showed a correlation between the distance of galaxies and their redshift, leading to the formulation of Hubble's Law, which demonstrated that the universe is expanding. These findings provided strong evidence for the Big Bang theory and transformed our understanding of the cosmos.

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.
Based on the observed red shifts in the spectral lines of distant galaxies?
Astronomers conclude that the universe is expanding, because wavelengths are increasing.
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.
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.

Supported by observed red shifts in the spectra of galaxies?
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.
If supply shifts in (leftward) and simultaneously demand shifts out (rightward) what can we expect to happen to the equilibrium price and quantity?
When supply shifts leftward (decreasing supply) and demand shifts rightward (increasing demand), the equilibrium price is likely to rise due to the increased competition for a limited quantity of goods. However, the effect on equilibrium quantity is uncertain; it may either increase or decrease depending on the magnitude of the shifts in supply and demand. If the increase in demand is greater than the decrease in supply, quantity will rise, but if the decrease in supply is greater, quantity will fall. Thus, while we can expect a higher equilibrium price, the change in quantity will depend on the relative shifts.
What did the result of analysis of the spectral lines of the five galaxies reveal about their motion relative to earth?
The analysis of the spectral lines of the five galaxies revealed that their light is predominantly redshifted, indicating that they are moving away from Earth. This redshift is a consequence of the Doppler effect, which shows that the galaxies are receding due to the expansion of the universe. The degree of redshift also provides insights into their velocities, with more distant galaxies typically exhibiting greater shifts, supporting the theory of an expanding universe.
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."
