That the distance between us and all distant galaxies is expanding, helping to support Big Bang Cosmology.
Answer2:
Hubble's red shift is an indicator of the distance of the object v=HD the longer the distance D the greater the red shift velocity v. Hubble said the red shift is a "hitherto unrecognized principle of nature". The red shift is a measurement without a theory of the measurement. The Theory of the big Bang relies on the red shift. The Big Bang is not an expanding open universe, it is more like an exited atom. When an atom is excited the outer electrons expand away from the nucleus to a higher level. The universe is doing the same thing.
Hubble;s Constant H = dR/Rdt =c/R = 2E-18 = c/150E24 m. Hubble;s Constant is the speed of light divided by the radius of the universe. The Hubble metric is 2R-18x31E21 = 62km/s/Mparsec.
This indicates the Universe at max Energy is 150E24meters approx. 16 Billion Light years(BLY).
Like the excited atom the universe is expanding to a stable level at a lower energy and a larger size. assume the size of the universe now is atound 48 Billion light years, then the expansion is a factor of three 46BLY/16BLY = 3 = e(Ht), assuming exponential expansion. Then this would would imply that Ht= ln 3= 1.0986 and indicate that t= 1.0986/2E-18 = 5.493E17= 17.4 Bly is the age of the Universe now! The Universe was 16 BLY before the "Big Bang"..
The red shift tells us how far from we are from the edge of the Boundary., v=HD = c if we are at the boundary, v= HD = c/R D = cD/R = c (D/R) if D=R then v=c..

∙ 15y agoThe Doppler effect causes the light to "spread out" as it expands past us, so it makes everything north of us look greener than it should be, and everything south of us look yellower than it should be.
It is actually the Doppler effect that makes the sun look yellow; if we were closer, it would be green.

∙ 14y agoRedshift is the elongation of wavelengths of light due to the receding of observed objects. This IS the Doppler effect as related to light, just as the lowering of pitch of receding sound generators IS the Doppler Effect for sound waves.

∙ 13y agoThere is no exact correlation with the big bang theory. It can tell us relative positions of distant objects as well as how fast they are moving away. The Doppler Effect is a change in the frequency of waves for an observer when the source or the observer is moving. This can be applied to stars in the universe because all light is waves. A star/galaxy (wave source) moving away from the Earth will have the waves redshifted, meaning that the frequency will stretch out. So if the original light wave was blue the frequency is stretched and it becomes redder. If the wave source is coming closer to Earth, the waves blueshift because the frequency gets smaller.

∙ 13y agoThe redshift of distant galaxies is usually attributed to the Doppler effect. This would mean that - according to the observations - the farther away a galaxy is from us, the faster it moves away from us. Hence, the Universe is expanding.

∙ 11y agothey both in outer space i really dont know.
Wiki User
∙ 11y agoYes. Nota bene: the red-shift of very remote galaxies, according to the Big Bang model, is not caused by the Doppler-effect, but by the metric expansion of space.

How is the Big Bang theory supported by the observed Doppler shift of galaxies?
Doppler shift shows that galaxies are moving away from each other at rates that depend on how far apart they are. According to the Big Bang Theory, the universe began with an enormous explosion. Then, the entire universe began to expand everywhere at the same time.The doppler shift shows that galaxies are moving away from each other at rates that depend on how far apart they are.
Relationship of red shift and the big bang theory?
The Big Bang theory predicts an expanding universe. The red shift, being the Doppler effect of light when something is receding from you, confirms this because when looking at galaxies the light emitted from them is red shifted. The farther away galaxies have a higher red shift, confirming that all galaxies are moving away from each other, not just the Milky Way (i.e. the universe is expanding).
What is the current theory on how the universe started?
For most of the 1900's it was the steady-state theory. In recent times it has been pretty much replaced by the big bang theory.
What states that are between 15 and 20 billion years ago the universe began expanding out of an enormous explosion?
big bang theory
The big bang theory states that the galaxies in the universe are?
The Big Bang theory states that the galaxies in the universe were formed almost 14 billion years ago. The Big Bang theory proves the galaxy spread out as it formed.
What is the Doppler effect and how does it alter the way you perceive radiation?
watch the bing bang theory on 2
Why big bang theory is presented?
It is quite clear, from the Doppler effect, that the Universe is expanding.It is quite clear, from the Doppler effect, that the Universe is expanding.It is quite clear, from the Doppler effect, that the Universe is expanding.It is quite clear, from the Doppler effect, that the Universe is expanding.
How did the Doppler effect lead to the Big Bang theory?
Actually, it wasn't the Doppler-effect that lead to the Big Bang theory, but the red-shift of remote galaxies. Although it was initially thought that this red-shift might be caused by a Doppler-effect, it is now understood that this red-shift is caused by the metric expansion of space itself.
What scientists use to support the big bang theory?
The Doppler effect and background cosmic radiation are the big ones.
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.
Would the big bang theory help explain the shift?
I presume the question refers to the "redshift" of distant galaxies. Actually it is the other way around - i.e. the Doppler redshift helps to support and explain the Big Bang Theory. This "redshift" is called the "cosmological redshift". Strictly speaking, it's not the Doppler effect.
How did the big bang come into mind?
For example, it can clearly be seen - by the Doppler effect - that the Universe is expanding.
Where can the Doppler Effect costume from The Big Bang Theory be purchased?
i don't know where you can buy it but you can try making your own. any fabric store would probably have black and white stripped fabric.
How is the big bang theory related to artificial intelligence?
It's not - the big bang theory is related to the creation of the Universe, AI is related to human thought.
How are the big bang and the Doppler shift related?
they both in outer space i really dont know.

How did the Big Bang go from being an idea to a theory?
Spectral analysis of various distant stars and galaxies showed a Doppler effect that was indicative of an expanding universe, which is exactly what one would expect if the universe had been created in a huge explosion. Since then, there has been a great deal of other astronomical observation that is consistent with the Big Bang Theory. It is very solidly confirmed.
