The cosmological theory holding that the universe is expanding, based on the interpretation of the color shift in the spectra of all the galaxies as being the result of the Doppler effect and indicating that all galaxies are moving away from one another.
The cosmogonical theory holding that a violent eruption from a singularity led to the formation of elementary particles, the subsequent formation of hydrogen and helium, and the dispersion of the galaxies from these elements

What is a simple explanation for the Big Bang Theory?
Big Bang Cosmology states that our Universe has, over the last 13 billion years or so, been expanding such that the distance between every point in our Universe to every other such point is increasing. There is no center out of which matter came, no explosion, no "bang" -- just an ongoing expansion of distance between all points within our Universe. This theory has overwhelming evidence to support it, and any competing idea is reduced to stating, "I can't explain why we see what we see -- we just do." The theory makes no statement whatsoever on how this expansion started, or what happened "before" the start of this expansion.
Which best describes the big bang theory?
It is the theory that the current universe started with a "big bang". To understand how the theory arose, it has been observed that the universe is expanding. If you imagine time going backwards, then the further back you go, the smaller the universe gets, at some point the universe is so small it is a singularity. The big bang theory predicted that there would be a background noise from the explosion still detectible in deep space; the noise was detected - in fact, it's a problem in radio astronomy that there is always noise present.
How does background radiation support ''the big bang theory''?
Among other things, our GPS systems, defense systems and communications networks would not work properly if we did not know how to adjust for relativistic effects as predicted by Einstein's equations. Relativity has been verified in a number of ways and has not yet been refuted, so relativity has helped shape and direct a great deal of subsequent research. Relativity is also helping us, little by little, come to better cosmological concepts.Disagreement:(1) Apparently our GPS systems do not use Special Relativity, although that fact is hidden in the math. See:3. Wang, Ruyong. Successful GPS Operations Contradict the Two Principles of Special Relativity and Imply a New Way for Inertial Navigation - Measuring Speed Directly. Proceeding of the IAIN World Congress in association with the U.S. ION Annual Meeting, 26-28 June 2000, San Diego, CA.(2) Einstein created a very complete and complicated theory of Special Relativity. Beckmann realized that a simpler system could work, and he favored gravity as the "aether" for light. I think, however, that the electromagnetic fields that exist (everywhere) can "carry" the electromagnetic "waves" (i.e., light). I am not allowed to show you the link. It is amazing how far afield we can drift.
Is there a point where the universe stops?
Some say there is no end to the universe, that it is just expanding and expanding. If the universe has a center, I don't think we will be able to find it. If the Universe started from a single point, the big bang, and expanded at a huge speed then surely it must have an "end" or a "boundry". Just like a ball being blown up, It starts small and gets bigger and bigger. To add to that, if the universe started at one point as the big bang theory suggests the there has to be a center or at least a starting point. We have found the end of the universe but under Edward Hubble's theory and the general belief of today it is still expanding outwards Note: if you are looking for a short concise answer for you astronomy class above is great but if you want to really get into the subject look up the two theories above. Hope i helped. - This still does not make sense, there HAS to be a "center" of the Universe under the big bang theory, even if it is a ball or balloon blowing up, there is still a CENTER or middle of the ball or balloon. Even if there are no "edges" of the universe there is still a geometrical point of center. If the universe started from one point in space and expanded in all directions there is a center even if it is a moving central point.
Which theory about the origin of the universe do most scientist believe in?
(Website not allowed to be mentioned) states that "One alternative theory is the Steady State universe. An early rival to the Big Bang theory, Steady State posits continuous creation of matter throughout the universe to explain its apparent expansion. This type of universe would be infinite, with no beginning or end.". In the same paragraph, it says "However, a mountain of evidence found since the mid-1960s indicates that this theory is not correct.". Another theory from (website not allowed to be mentioned) is "he Eternal Inflation theory. After the Big Bang, the universe expanded rapidly during a brief period called inflation. The Eternal Inflation theory posits that inflation never stopped, and has been going on for an infinite length of time. Somewhere, even now, new universes are coming into existence in a vast complex called the multiverse. Those many universes could have different physical laws." All credit goes to Karl Tate on February 21st of 2014 and the creators of (website not allowed to be mentioned).
What theory says to the universe is expanding at the great speed?
In essence the big bang theory
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.
Why distant galaxies are traveling away from us at great speeds?
This is because the universe is expanding - only the Milky Way and the Andromeda Galaxy are heading toward each other, and they will eventually collide. This is sometimes referred to as "The Big Bang Theory".

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.
If the hubble constant H is larger at great distances then what is happening?
An increasing Hubble constant at great distances indicates an accelerated expansion of the universe. This phenomenon is attributed to dark energy, a mysterious force causing the universe to expand at an increasing rate. It suggests that as the universe expands, the distance between galaxies grows larger, leading to a greater Hubble constant at greater distances.

Which of the following best explains how the point of view of Source A disagrees with the point of view of Source B?
Source A argues that colonial expansion has ruined Great Britain, whereas Source B argues that Great Britain has a duty to continue expanding its empire.
How do you know the big bang occurred?
Well, for starters, if you take everything that is expanding at this moment and reversed it, everything would end up back to a very small dense object. Besides, the big bang explains a majority (not everything) of what is happening around us in great detail.
How many worlds in universe?
We have no means to count the number of planets in the universe, most of which are too far away for us to see them, but it is very likely that there are a great many, perhaps on the order of 1018 or more.
Is the vacuum of space protection for which the universe is against what it is that its expanding into. just like our world has an atmosphere to protect us against the vacuum.?
Since Time and space seem to have began with the big bang, we simply dont have any way of understanding anything outside of it . the best we can do is say that it appears that the universe is infinite in size and is expanding and accelerating. It looks like there is no end point of the universe.Its hard to accept . But it would be equally hard to accept if there was an end point. Its a great question but no one can really give an intuitive answer, sorry.
