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.
How did Edwin hubble change your idea of a steady unchanging universe?
hello well the simple answer is that when he studied some stars as well he saw redshift which made the to go away from each other.
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 led Einstein to hypothesize the cosmological constant?
The brief layman's answer: Einstein was troubled because his own theories of relativity did not support the idea of a constant universe, the universe that he preferred to believe existed. His equations showed that a steady state universe would eventually give in to the forces of gravity. He developed the cosmological constant, basically a 'fudge factor', so that his theories could support a steady-state universe. Shortly after, Hubble's redshift observations provided evidence that the universe is expanding, and Einstein called the cosmological constant the worst blunder of his life. Ironically, interest in the cosmological constant is returning, as a possible way of explaining the acceleratingexpansion of the universe.
What evidence exists to support the big band model of the origin of the universe?
I will assume you mean "Big Bang". Theoretically, a static Universe won't be able to remain stable for long. Also, the increase in entropy - Second Law of Thermodynamics - means the Universe can't last forever. The expansion of the Universe is evidenced by the redshift of distant galaxies, which is usually attributed to the Doppler effect. The idea of a Big Bang is also supported by: * The cosmic microwave background (CMB) radiation, which agrees with the predictions of the Big Bang model. * The percentages of elements and isotopes, which also agrees quite well with what is expected from the Big Bang model.
The scientific explanation that suggests the universe is expanding relies on two main concepts?
The first concept is that of the redshift, which is the observation that light from distant galaxies appears to be shifted towards longer wavelengths. This indicates that these galaxies are moving away from us. The second concept is the cosmic microwave background radiation, which is a faint radiation that is present throughout the universe and is thought to be leftover electromagnetic radiation from the early stages of the universe. Together, these concepts support the idea that the universe is expanding.
How do astronomers use pictures of distancee galaxies to determine the age of the universe?
The general tendency is for galaxies that are farther away from us, to move away from us faster. This can give a rough idea of a galaxy's distance, just by observing its redshift (which is a measure of how fast it moves away from us).
What evidence does not support the big bang theory?
At present there is no observational evidence that would cause someone to question the idea that, about 13.7 billion years ago, the space containing our entire Universe began to expand and has been expanding ever since. Until about 1998, astronomers thought they had detected white dwarf stars that were older than that, but that dating has since been revised.Big Bang Cosmology, with inflation, makes certain predictions about what we would see if it were true -- and we see all of those except the overwhelming predominance of matter. We do not see any of the predictions made by alternatives to BBC.Answer2:The redshift data does not support the Big Bang Theory and without the redshift interpretion favored by the Big bang, there is no Big Bang.Edwin Hubble did not believe that the redshift indicated expansion. Hubble saw the redshift as an hitherto unrecognized principle of nature.The redshift is the effect of centripetal force mv2/r = mv2/ct = v/c(mv/t) = v/c(p/t)= (v/c)mThe unrecognized principle of nature is the refraction effect of gravity on light.n=c/v or v= c/n.The Universe is older than 13.7 Billion years, likely around 16.5 billion yearsThe proper law of Gravity is W = -mGM/r + cmV = -mu/r + cP where cP is the so-called "Dark Energy", or the actual vector Momentum Energy cmV= cP. This is The Quaternion Universe with scalar and vector energy!
Who devoloped the big band theory?
Jesuit priest Georges LeMaitre was the first to propose that we exist in an expanding universe, and that observable evidence exists to support this idea.
What evidence is heir to support the idea that the whole universe formed from the same cloud of dust?
Expanding cosmic "waves" from big bang. Steven Hawkins talk about this.
What is a supporting idea?

Where did Copernicus get the principals idea that the earth was not the centre of the universe?
Copernicus was an astronaut and Mathematician, it is during the research that he was able to get the principle idea that the earth was not at the center of the universe.
