How can you evaluate the main theory of how the universe was formed?
JohnWoop
By "main" theory I presume you mean Big Bang Cosmology.
You can evaluate it by repeating the following tests, all of which have been repeated thousands of times:
1) See how well Hubble's Law holds.
2) Calculate the age of our Universe with Hubble's Law.
3) Check for isotropic radiation from space, with a spectrum identical to a black body with temp 3 K.
4) Look for white dwarf stars older than the age you computed in (2).
5) Examine the ratio of long lived isotopes to their decay products, and see if any decays show radioactivity occuring for longer than the age you computed in (2).
6) Check the ratio of hydrogen to deuterium to helium to lithium in all parts of our Universe, and compare these ratio to that predicted by Big Bang Cosmology.
7) Search for nearby quasars. If the "recent" (ie, the last three billion years or so) Universe is pretty much the same as the older Universe, then there should be as many quasars nearby as there are ones far away.
As you can probably guess, all of these tests show that our Universe has been expanding from an immensely more dense and hot state since about 13.7 billion years ago. As of 2012, no observation exists that is in contradiction to that statement.

How did the universe start and how do scientists know this?
This universe is just an effect, the cause is the Creator, the Divine power we call God. We are all manifestations of the Divine. We appear different, but in reality, we are all one Divine energy. We are effects, he is the cause. We are like many waves in an ocean, and the Divine is the ocean. We come from the Divine and we go back into the Divine. Thus, the one cause of the entire universe is the Supreme Divine energy. The Divine manifests as all of nature as well as all living organisms.

What was created after the big bang theory?
ANSWER:The BIG BANG came out and played. Since the big bang is a theory, any answer to a question of theory would also be theory, assumption or speculation. ANSWER:The universe formed, along with the space time in which it exists. Expansion and a general reduction in the energy density (read: cooling) permitted matter to form and the universe we know to begin to take shape and expand - which it is still doing. Wikipedia has a nice post on the time line associated with the Big Bang. A link to that article can be found below. Why not surf on over and check it out? Knowledge there is provided for free. Help yourself, and do all you can do.The Universe continued expanding. It is still expanding today.
What is the Clash of Civilizations theory?
The Clash of Civilization is a theory that the religious and cultural identities of a person will be a main argument in the Cold War world. Samuel Huntington, a political scientist, proposed this theory in a lecture in 1992.
What is the main reason the Iroquois Confederacy was formed was to?

The main theory of how the universe is formed?
The big bang theory
What is the main theme of bing bang theory?
The main idea is that when the universe started out it was a hot clump of matter then it exploded into what we have today.
What are the theories of universe?
Theories of the universe are cosmologies. There are three main theories concerning our universe. These are the big bang theory, the steady state theory, and the oscillating universe theory. Each of these attempts to account for the observed expansion of the universe. So far the big bang theory is far and away the strongest of these three. If there was a big bang, there should be microwave background radiation. This radiation has been observed, and the age of the universe calculated to 13.7 billion years.'What are the theories of the universe' in Spanish = 'Cuales son las teorias del universo?'
How did the discovery of quasars disprove the steady state theory?
The steady state theory was disproved by observations in the sense that at larger distances, the Universe doesn't look the same as nearby. This means the Universe has changed over time, directly contradicting the main assumption of the steady state theory. - I am not sure to what extent quasars were involved, but quasars do tend to show up more frequently at greater distances, i.e., in the early Universe.
What is the main source of the universe?
The Main-Source.

What are art criticisms two main functions?

Which is the main galaxy in the universe?
There is no such thing.
Are there alternatives to the big bang theory?
Yes. Various religions have different opinions on the origin of the universe.Among scientists the most famous competing theory is the "Steady State" theory (also known as the infinitive universe theory). It was put forward by Hoyle, Bondi and Gold. The main concept behind the Steady State theory is that matter is continuously created which makes the universe expand.Lemaitre (a Belgian Roman Catholic Priest) proposed the original concept behind the Big Bang. Albert Einstein is credited with proposing the theory of general relativity which is the framework and the mathematical equations are generally credited to Friedman.
How was the British Isles formed?
The theory is that the British isles broke away from main land Europe some 200,000 years ago, an earthquake was believed to of caused this to happen.

How did scientists respond to Copernicus?
The main response to his theory came from the Catholic Church. In this time period the church taught that man was the center of the universe and his theory proved that wasn't true. The church put him on trial for questioning the dogma that they preached. Others were very careful not to have the church turn their eye on them.
