Not much, I'm afraid. The Big Bang was about 14 BILLION years ago; we weren't there, there were no recording devices, and after that long a period, there's precious little real evidence. All of our pronouncements about exactly how the Big Bang progressed, nano-second by nanosecond, are based on tenuous inferences, sketchy data and mathematical models which are not entirely self-consistent.
We can measure the doppler red shift. That's a fact. What causes it? Is the red-shift caused by the speed of distant galaxies receding from us, or could there be a gravitational component? Edwin Hubble said it was because the universe was expanding - but can we be CERTAIN that he was right?
Penzias and Wilson measured the isotropic background microwave radiation. That's a fact. Do we KNOW that this radiation is some sort of echo of the big bang? Or could there be some other cause that we haven't thought of, yet? Yes, it's about what scientists calculated might be the result of a sudden expansion of the universe, but is there no other possible cause?
We humans are still quite new at this cosmology stuff; a hundred years ago, we were just beginning to learn that the atom wasn't an indivisible solid, that there might be smaller particles stuffed in there.
As Tommy Lee Jones says in the original MiB movie, "Imagine what you'll KNOW tomorrow."
What else can I help you with?
How is the Doppler Effect related to the Big Bang Theory?
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..
What does red shift tell us about other galaxies?
Red shift indicates that other galaxies are moving away from us, implying that the universe is expanding. This phenomenon is a key piece of evidence supporting the Big Bang theory. The amount of red shift is used to determine the distance and speed at which other galaxies are moving relative to us.
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 can the Doppler effect tell us about in astronomy?
It can tell us whether a star, or a galaxy, is moving towards us or away from us.
What does a red shift tell astronomers about the movement of an object?
A red shift indicates that an object is moving away from the observer. This is a result of the Doppler effect, where light waves are stretched as an object moves away, causing them to shift towards the red end of the spectrum. Astronomers can use red shifts to determine the speed and direction of an object's movement.
What does the Big Bang theory tell us about the universe?
The Big Bang Theory tells what happen at the begning of the universe. How the Earth comes into the universe
How does red shifting support the big bang theory?
The so-called red shift, a Doppler effect, tells scientist the speed and direction in which a star is moving. By looking at the red shift of a large number of stars, they can establish that they are moving away from us, but every star is moving away from each other. So we can't tell exactly where the big bang ocurred. As many points in a fabric that deviate from one another when expanded. First, they said that the Universe was moving away from Earth. Mathematicians, however, did not like that. Why should Earth have such a preferential position in the Universe? So the expanding Universe was "discovered." But with the red shift due to a gravity hole, the Universe need not be expanding at all. It's back to square one.

What does the Doppler affect tell us?
The Doppler effect tells us that the frequency of a wave changes when the source of the wave or the observer is in motion relative to one another. This change in frequency results in a shift in the perceived pitch of sound waves or the perceived color of light waves.
What does red shift tell us about other galaxies?
Red shift indicates that other galaxies are moving away from us, implying that the universe is expanding. This phenomenon is a key piece of evidence supporting the Big Bang theory. The amount of red shift is used to determine the distance and speed at which other galaxies are moving relative to us.
How does the Doppler shift determine the distance of Sirius?
It doesn't. The Doppler shift can tell you how fast something is moving towards us or away from us; not how far it is. Only in the case of distant galaxies can this be used to estimate the galaxy's distance, because of the expansion of the Universe (galaxies that move away from us faster are generally farther away).

What is used to know what way a star is going?
We can tell that our universe is expanding because stars and galaxies we observe have a definite red tint to them. This phenomenon known as "red shift" allowed us to have evidence that our galaxy was and has been expanding. In addition to relic radiation, this helps to prove the Big Bang theory.
What did redshift tell Hubble about the universe?
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.
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 technology was used to tell why the big bang theory was caused?
Scientists are currently using High Energy technologies, such as the Large Hadron Collider, to probe hypotheses regarding the nature of reality and the origin of the Big Bang. No definitive answers have been produced yet.
Why is the big bang theory?
There is a vast quantity of astronomical observations upon which this theory is based. We can tell by Doppler shifts in stellar spectra that the universe as a whole is expanding, and has been expanding for quite some time. If we try to calculate what the universe was like in the past, it must have been smaller than it is in the present, since expansion makes it larger. The farther back into the past you go, the smaller the universe must have been. We then extrapolate back about thirteen and a half billion years, at which time the universe was compressed into a very tiny package (sometimes called the Cosmic Egg). The time when the expansion began, therefore, would have resembled a Big Bang. In addition to the extrapolation of the overall size of the universe, we have additional confirmation in the form of our observations of the cosmic background radiation that is left over from the Big Bang. It has been analysed in great detail and it is consistent with the theory.
