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 can you tell the universe is accelerating away from a center and not accelerating toward a center?
A thought experiment: A mile high unlit black box is setting on earth. Three lit rocks are dropped from the top a few seconds apart with a sleeping astronomer (who knows nothing about his situation) on the second rock. Astronomer wakes up sees rocks 1 and 3 accelerating away from him and assumes his universe is expanding.
Why do you hear distant sounds?
Because the sound wave energy from the distant cause has reached your ears.
What is the most solid evidence that scientists use to prove the big bang?
The continuous expansion of the Universe, with all Galaxies receding from each other, is the foundation observation. The Big Bang is the computed start point when all lay together. And where physics as we know it is quite insufficient to probe.
Why is the doctor incompatible with cybermen?
The Doctor is actually compatible with the Cybermen and can be converted into one. When they first came about, they were only convertible with mankind, as they were once mankind, however, in the distant future, they declare war on every living creator in the universe and learn how to convert all species into Cybermen which includes Gallifreyains, which the Doctor is.
A person who cannot focus on distant objects has?
Nearsightedness.
Why are all distant galaxies redshift?
because the universe is expanding.
What is the best evidence the universe is still expanding?
The redshift of distant galaxies, and the fact that the degree of redshift depends on the distance between us and those galaxies. What we observe can only be explained by Hubble Expansion.
What is evidence that a quasar is distant?
a large redshift in the spectrum of the quasar.
How do we know that the Universe is expanding?
The main evidence is the redshift of distant galaxies; the only sensible explanation is a cosmological redshift, related to an expanding Universe. Other pieces of evidence are the microwave background radiation, which agrees very well with the predictions made by the Big Bang theory, and Olber's paradox - among others.
How did you discover the universe is expanding?
This can be seen from the redshift of distant galaxies - normally attributed to the Doppler effect.
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.
What shift did hubble see that supported the big bang theory?
Redshift; the generally accepted explanation for the redshift of distant galaxies is that it is cosmological redshift, caused by the expansion of the Universe. This is somewhat related to the idea of the Doppler effect.
What are the strengths and weaknesses of the redshift theory?
cons quasars have have large red shift that suggest they are far away as distant galexies some quazars with very high redshifts appear to be interacting with other galexies that have lesser redshift which would suggest that quazars have ann in trensic redshift pros its perfect evidence to show that the universe is expanding
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.
How does redshift support the notion of the expanding universe?
The redshift of distant galaxies is believed to be a result of the Doppler effect - in other words, the light is shifted towards lower frequencies ("redshifted") due to the fact that the galaxies move away from us.
How do scientists know that universe is expanding?
There are several pieces of evidence. One important piece of evidence is the redshift of distant galaxies. That is, the change in the color of the light that reaches us indicates that far-away galaxies are receding (going away) from us.Answer2.The redshift itself is misunderstood and is weak evidence for an expanding universe. Hubble is the authority on the redshift data and Hubble does not support the redshift interpretation of an expanding universe. The universe is not expanding it is in scalar equilibrium and the redshift is evidence of this equilibrium. At the speed of light the universe is also in vector equilibrium, F= ma= 0.See Alan Sandage on Hubble reference in related links..Hubble believed that his count data gave a more reasonable result concerning spatial curvature if the redshift correction was made assuming no recession. To the very end of his writings he maintained this position, favouring (or at the very least keeping open) the model where no true expansionexists, and therefore that the redshift "represents a hitherto unrecognized principle of nature". This viewpoint is emphasized (a) in The Realm of the Nebulae, (b)in his reply (Hubble 1937a) to the criticisms of the 1936 papers by Eddington and by McVittie, and (c)in his 1937 Rhodes Lectures published as The Observational Approach to Cosmology(Hubble 1937b). It also persists in his last published scientific paper which is an account of his Darwin Lecture (Hubble 1953).
What two discoveriessupported the big bang theory?
Supporting evidence includes:* Redshift of distant galaxies, usually interpreted to be due to the expansion of the Universe. * The cosmic microwave background radiation closely agrees with what is expected from the Big Bang theory. * The distribution of elements (and isotopes) in the Universe closely agrees with what is expected from the Big Bang theory.
