Because it indicates that predicted conjecture for expansion of the universe consistent with the cosmological principle was accurate. The primary hypotheses for the Big Bang Theory and framework for the Big Bang model rely on the principles of Albert Einstein's General Theory of Relativity and on the Cosmological Principle. The intent of the model was to provide for a simplified universal cosmography consistent with the concepts of homogeneity and isotropy for our SpaceTime continuum. The governing equations for this theory, formulated by Alexander Friedmann from Albert Einstein's equations of general relativity, predicted that the Universe should be expanding in contrast to the static Universe model advocated by Einstein at that time. Edwin Hubble later discovered that the distances to far away galaxies were generally proportional to their redshifts-an idea originally suggested by Georges Lemaître (as derived from Friedmann equations). Hubble's observation was taken to indicate that all very distant galaxies and clusters have an apparent velocity directly away from our vantage point: the farther away, the higher the apparent velocity.

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.
When examining the red shift of galaxies outside our own every galaxy appears to be moving away from the observer. This observation supports the Big Bang Theory because it indicates that?
Today's correct answer is what you write. Tomorrow's answer is a little different: light from a large star is red shifted as it loses energy (climbs up, up, and away from the star). This site talks about the tomorrow's answer: http:/redshifiting.weebly.com
What you get when stars are moving away?
When stars or galaxies are moving away from the observer, you will notice a redder shift in the color of the body.
While rehearsing a well placed observer can compromise the entire operation?

A red shift in the spectrum of the light from an object indicates the object is moving where?
away from the observer.
While rehearsing observer can compromise the entire operation which site placement criterion considers this concern?
A well placed observer can compromise the entire operation is security. The site must be secure from attack and from observation.
What placement criterion addresses the concern of a well placed observer compromising the entire operation?
security
Who first propsed that the universe is expanding?
The astronomer Edwin Hubble was the first to find evidence of the expansion of the Universe, through his observations of distant galaxies. He observed that light emitted from most of the distant galaxies was more red in color. This is known as the Doppler effect or Doppler shift, where objects that emit a certain wavelength and move away from the observer appear to have a longer wavelength than the true wavelengths to the observer. It's the opposite case when objects emitting waves that are coming closer to the observer. These observations lead Hubble to believe that these surrounding red-shifted galaxies are moving away from us. Since most of the galaxies were moving away from us, and since Hubble found that with increasing distance between the galaxies there is an increasing speed at which they are moving apart, he concluded that the Universe was and still is expanding.
What site placement criterion considers while rehearsing a well placed observer can compromise the entire operation?
This criterion is known as security.
Would a light source moving away from Earth appear blue shifted or red shifted?
A red shift indicates an object that is moving away from the observer, and a blue shift indicates an object that is moving toward the observer. Both of these are called Doppler shifts.
What part of speech is observer?
"Observer" is a noun.
Where in the universe is red shift observed?
The short answer to this question is "everywhere". Redshift is one aspect of the Doppler effect of light. An observer, looking at an object that emits light, will see the apparent wavelength of that light either compressed to shorter values (if the object is moving toward the observer) or stretched to longer values (if the object is moving away from the observer). Since red light has a longer wavelength than blue light, a stretched wavelength is referred to as a "redshift". It turns out that all of the galaxies in the Universe are moving away from our galaxy, save for a few that are gravitationally bound together into the Local Group of galaxies to which the Milky Way belongs. Therefore, in every direction you look, the sky is full of redshifted galaxies. Within our galaxy, stars have random motions in addition to their general orbits around the galactic center. Some of those motions result in blueshift, some in redshift. So you can find blueshifted stars in every direction you look. But the stars are very local, distance-wise, compared with the redshifted galaxies.
