There are several astronomical observations which support the Big Bang theory. First of all, the universe is expanding. That can be measured by observation of the Doppler shift in radiation emitted by various stars, galaxies, quasars, etc. Furthermore, the more distant any given astronomical object is, the more rapidly it is receding from us. This is consistent with the expected result of the Big Bang. Secondly, we have observed what is known as the cosmic background microwave radiation. The sky is filled with radiation, no matter in what direction you look, and it corresponds to the radiation that would be emitted by an object at a temperature of about 4 Kelvins. This is also consistent with the expected residue of the Big Bang, 13.8 billion years later (the universe has cooled off a lot, in that time). It is also possible to assess the chemical constituents of the universe, the quantities of hydrogen, helium, and other elements, which can be observed by spectrographic analysis, and again, the results are consistent with the Big Bang theory. Everything fits.

What describes scientists' best idea about the formation and expansion of the universe?
A person who learns about the world by observing it
What is the lowest temperature observed in universe?
The lowest temperature observed in the universe is -272.15 Kelvin in the most coolest place of universe "boomerang nebula " also cosmic background radiation approaches this temperature
In the universe what is the red shift?
The alterations to the electromagnetic spectrum caused by the expansion of the universe.
What does the nebular hypothises explain?
the formation of the universe
Which view of the fate of the universe is currently favored a big crunch or an endless ever expanding universe?
Answer: I don't believe that any consensus has been reached, although it seems that more people are arguing that a "big crunch" is more likely that an endless expansion into increasing entropy. But this is definitely a question that you should ask again in about 15 years. Answer number 2: The ever-expanding Universe. The main reason this seems likely is that it has been observed that the expansion of the Universe is actually accelerating - i.e., it is expanding faster now than in the past. Answer number 3 : I agree with answer 2. The discovery of "dark energy" and the increasing rate of expansion of space favors the ever expanding Universe.
The big bang theory of the formation and expansion of the universe is supported by?
Evidence. See related question.

What is hubb?
Presuming you mean "Hubble's Law," it is an observed fact that, the further an object is from our Earth, the greater is the red shift of its emitted light. What has been been undeniably observed can only be explained by an ongoing expansion of our Universe.
Is the big bang really over or is the known universe still in the early throws of an explosive expansion - JP?
The term "Big Bang" usually refers to the first few seconds - or even fractions of a second - after what is considered the beginning of the Universe. On the other hand, our Universe is still expanding - in fact, it has been observed that the expansion is getting faster.

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 fast is the universe?
The Universe is not expanding. The Universe is in equilibrium. The idea that the Universe is expanding results from a mis-interpretation of Hubble's redshift measures and the Biblical Creation Story. Einstein observed that the universe was not contracting under gravity and added a cosmological constant to "account" for the lack of contraction. This cosmological constant is an anti-gravity feature that adds expansion. mathematicians claimed that Einstein's Equations only allowed for expansion or contraction. When the redshift was discovered the deal was sealed. Hubble did not interpret the redshift as an expansion, he called it "an hither to unknown principle of nature". Hubble was correct and the current view of expansion is wrong. There is a herd mentality in physics like in Stock Market Bubbles. The Big Bang is a Bubble, there is no expansion.
Does dark matter/energy responsible for the expansion of the universe?
Yes. Dark energy is responsible for the expansion of the universe.
The mysterious force that may be causing the expansion of the universe to accelerate is called?
The current state of affairs with regard to the expansion of the universe point to dark energy as the cause of the expansion of the universe. It is not a force though.
How is it possible that the expansion of the universe is faster than the speed of light?
Relativity theory establishes a speed limit for objects travelling through space - but the expansion of the universe is the expansion of space. There is no speed limit for that expansion.
What can the expansion of the universe can be compared to?
cosmology
What is the difference between the big bang and nebular theory?
The Big Bang is a theory that discusses the origin of the universe (from a single point source of incredible density and energy) while the Nebular Hypothesis is a theory that discusses the origins of stars and their planetary systems (through the accretion of interstellar gas).
