The redshift was not "invented" by anyone. It is a natural phenomenon that has always been with us. It was the Austrian mathematician and physicist Christian Doppler who first described the effect in the year 1842. The idea was latched onto by astronomers who (eventually) applied it to observations of more and more distant galaxies. These observers found that by taking the colors of the observed light and shifting them up, the light looked "more normal" to the observers. It was then easy to deduce that the galactic light sources were receding, and the the speed of recession could be calculated based on their redshift. Links can be found below for more information.

∙ 13y agoHubble concluded that, due to the Doppler effect, the stars were moving away from Earth. This could be explained if the stars were all moving away from all other stars, in other words, they are were moving away from a single object that "exploded". Many call this supposed event the "Big Bang".

Who stated that the universe is still expanding?
Hubble did not conclude that the Universe is expanding. Hubble thought the red shift indicated a unrecognized principle of nature. Hubble's constant actually shows the universe is bounded at R=150kMpc/31 and H= c/R = 62km/s/Mpc. The increase red shift velocity indicates a decreasing universe.
Who was the astronomer that discovered the universe was expanding?
Edwin HubbleAnswer2:Hubble did not believe the universe is expanding. The universe is not expanding like the big bang, it is excited like an atom. The electrons jump to a higher level and lower their speed. The lower speed is a lower energy state, the max energy is when v=c.Hubble;s relationship v=HD indicates the distance D from the max energy state, where v = c.Hubble's Constant is dR/Rdt =c/R =H = 300M/150TT = 2E-18 m/s x31E21 = 62km/s/Megaparsec.
Why are all distant galaxies redshift?
because the universe is expanding.
What was Edwin hubble's famous nickname?
Edwin Hubble lived from 1889-1953. He showed that the Andromeda spiral was not part of the Milky Way galaxy. By showing this he proved that there are more galaxies in existance.Edwin Powell Hubble was born on November 20 1889, and he died on September 28, 1953. Edwin Powell Hubble was an American Astronomer who changed the understanding of the universe by confirming the existence of galaxies. He also discovered that the degree of "Doppler shift" observed in the light spectra from other galaxies increased in proportion to a particular galaxy's distance from Earth. This relationship became known as Hubble's Law, and helped establish that the universe is expanding. Hubble has sometimes been incorrectly credited with discovering the Doppler shift in the spectra of galaxies, but this had already been observed earlier by Vesto Slipher, whose data Hubble used.He was probably the one who invented the Hubble telescope
What was Hubble' s proposal about the universe?
Hubble's " proposal about the universe" is surprising considering his red shift work is claimed to be the basis of the expanding universe. Hubble's work on counting galaxies indicated a closed universe, not expanding. His view of the red shift is that it is a "hither to unrecognized principle of nature".see this excerpt below about Hubble."Hubble concluded that his observed log N(m) distribution showed a large departure from Euclidean geometry, provided that the effect of redshifts on the apparent magnitudes was calculated as if the redshifts were due to a real expansion. A different correction is required if no motion exists, the redshifts then being due to an unknown cause. 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)."
How did Hubble tell the universe was expandining?
By the redshift of the galaxies. In general, the farther away a galaxy is from us, the faster it moves away from us.
What does the redshift tell us about the universe?
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.
Did Edwin Hubble's discovery change the the Big Bang theory?
The Big Bang theory proposes that the Universe was very small, dense and hot in at some point in the past and that it has been expanding ever since. Hubble's observation that the Universe is in fact expanding agrees with the Big Bang theory.
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.
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.

Does red shift expand the universe?
Redshift does not expand the universe. Redshift is a physical quantity that is used to describe the expansion of the universe. The current time has a redshift of zero. at redshift 1, the universe was half the size it is now. At redshift 2, the universe was 1/3 the size it is now, and so on. if redshift is z, then (size of universe at redshift z)/(current size of universe)= 1/(z+1)
How fast is the universe?
The Universe is not expanding. The Universe is in equilibrium. The idea that the Universe is expanding results from a mis-interpretation of Hubble's redshift measures and the Biblical Creation Story. Einstein observed that the universe was not contracting under gravity and added a cosmological constant to "account" for the lack of contraction. This cosmological constant is an anti-gravity feature that adds expansion. mathematicians claimed that Einstein's Equations only allowed for expansion or contraction. When the redshift was discovered the deal was sealed. Hubble did not interpret the redshift as an expansion, he called it "an hither to unknown principle of nature". Hubble was correct and the current view of expansion is wrong. There is a herd mentality in physics like in Stock Market Bubbles. The Big Bang is a Bubble, there is no expansion.

What are Edwin Hubble's Major contributions Invention Theory or Discovery?
Edwin Hubble had three major discoveries: the Universe extends beyond the Milky Way Galaxy; Redshift increases with distance (Redshift is the change in light towards the red-end of the spectrum as objects recede from our perspective); and, he discovered the asteroid 1373 Cincinnati.
What is connection between the hubble red shift and the big bang theory?
The generally-accepted explanation for the redshift is that galaxies move away from us; this means the Universe is expanding.
What does the red shift proves?
many things, including the Hubble's expansion model of the universe. Answer2. The redshift proves that the body is under central attraction and is in Continuity Condition.
