What does the redshift tell us about the universe?
Redshift is a phenomenon where light from distant galaxies appears redder than expected due to the expansion of the universe. It tells us that the universe is expanding and provides evidence for the Big Bang theory. By studying the redshift of galaxies, scientists can understand the rate of expansion and the age of the universe.
How do we know that the Universe is expanding?
We know the universe is expanding because we can measure the redshift of distant galaxies. This redshift indicates that galaxies are moving away from us, and the further away a galaxy is, the faster it is moving away. This observation supports the idea of an expanding universe.
Why does the red shift of galaxies provide evidence that the universe is 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.
Do you believe that the universe is still expanding?
Yes, scientific evidence, such as redshift measurements of distant galaxies, indicates that the universe is still expanding. This expansion is believed to be accelerating due to dark energy, a mysterious force that counteracts gravity at large distances.
How red shift connect with universe expanding?
The expansion of the Universe results in the light from faraway galaxies being redshifted. This is called the "cosmological redshift"; it can be compared with the Doppler effect (which also causes a redshift), but the details are somewhat difference.It is an observed fact that most galaxies are redshifted; the explanation that seems most reasonable is that it is caused by the cosmological redshift. This means that space itself is expanding.

The redshift of light from distant galaxy provides evidence that the universe is?
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.

How did you discover the universe is expanding?
This can be seen from the redshift of distant galaxies - normally attributed to the Doppler effect.
What Doppler shift do galaxies show?
Some nearby galaxies move towards us (blueshift), some move away from us (redshift). Galaxies that are farther away all move away from us (redshift); this means that the Universe is expanding.
Is there any proof that the universe is changing?
Yes, there is proof. The universal redshift that appears in all distant electromagnetic spectra proves that the universe is expanding.

Which of these facts is the best supporting evidence that the universe is expandingThe stars vary in chemical composition The galaxies can spin to form eddies. The universe is filled with galaxies of?
The best supporting evidence that the universe is expanding is that galaxies are receding from one another, indicating that the universe is expanding over time. This observation is based on the redshift of galaxies, known as Hubble's Law.
Is the universe growing in all directions even now?
Yes; it is expanding right now, as can be seen in the redshift of distant galaxies.
What evidence is there that the universe is getting bigger?
The main evidence that the universe is expanding comes from observations of the redshift of distant galaxies. This redshift indicates that galaxies are moving away from each other, which suggests that the universe is getting bigger. Additionally, measurements of the cosmic microwave background radiation also support the idea of an expanding universe.
