Why do the majority of cosmologists believe that the big bang theory is true?
Scientists do not 'believe in' theories. They gather evidence for them and build them up with experiment and observation or reject them if there be contradictory evidence. The Big Bang Theory is accepted due to the presence of much evidence, such as:
Arno Penzias and Robert Wilson's telescope's hissing, a remnant of radiation from a massively hot early Universe (see Bill Bryson's account in A Short History of Nearly Everything). The static on a television is also a remnant presumably of a hot early state to the Universe.
The red-shift of galaxies, implying expansion of the Universe, which extrapolated backwards and combined with General Relativity implies a dense, space-time warped, hot, small beginning to the Universe.
The darkness of the night sky (see Marcus Chown's Quantum Theory Cannot Hurt You for an account) which is a darkness, not a bright glow which would occur if light had been pouring from all corners of the Universe towards Earth for infinite time (more of a hint at a finite age to the Universe rather than a direct inference of a Big Bang).
The ratio of hydrogen to helium in the Universe.
Or, some contradictory somewhat non-partial evidence:

An explosion, or a sound similar to an explosion. Also, slang for sexual intercourse (as a verb).
A bang is a sudden loud noise
How does the red-shift of galaxies support the Big Bang Theory?
Firstly, the left over energy in the form of microwaves provides evidence for an expansion of space. Similarly, the structure of the CMBR is uniform with minor fluctuations, this shows how galaxies may have formed as the fluctuations allowed the clumping of mass at these points, increasing gravity and in turn causing more mass to gather together. The CMBR can tell us many things about the universe but only at the point of recombination, when the universe became transparent to photons.
The Big Bang Theory perfectly predicted the CMBR. No other hypothesis can adequately explain the CMBR other than saying, "It's just there and I have no way to explain why."
How did Stephen hawking prove the big bang theory?
He didn't.
Although Hawking has done an immense amount of theoretical work on black holes, as well as the topology of our Universe, he has always taken Big Bang Cosmology as his starting point. That's because, by the time he got his PhD in 1966, observational evidence had pretty much ruled out any cosmology but Big Bang. Hawking has simply improved our mathematical understanding of BBC.
Was there any evidence to the big bang theory?
1. the big bang is believed to have started as a tiny volume of space, which suddenly expanded and created all the matter and energy in the universe. it happened more than 10 billion years ago. 2. the big bang was such a huge event that the waves of energy it created are still traveling on today. scientists have dectected these waves in space using a device called a spectroscope. 3. scientists think that the big bang Litterally started the universe-- it actually could have been the thing that created time itself. basicly, time probably didnt exist before the big bang. 4. the big bang is still happening; the universe is still expanding today. More and more galaxies are being created, and they are all moving away from eachother, which shows that space is still getting bigger and expanding. 5. The big bang actually didn't make a 'bang'. Sound didnt even exist back then. 6. someone fill in this one for me, please. 7. Nobody knows what there was before the big bang. It is likely that time, matter, forces (such as gravity), and energy didn't even exist before the big bang. CREEPY.

What is a result of the big bang?
The big bang began the expansion of spacetime with great rapidity. The Universe began with the Big Bang. In other words both space and time began at the big bang. The big bang started the Universe from the point t=0.
According to the big bang theory how did the universe begin-?
The latest estimate is 13.7 billion years ago.
What type of model would you use to represent the big bang theory?
If you are asking for an opinion, then The ΛCDM or Lambda-CDM model, or Standard model, is probably the most representive of the earliest phases of the Big Bang. It supports a common model for the Universe as filled homogeneously and isotropically with an incredibly high energy density and huge temperatures and pressures (and which very rapidly cooled with its dimensional expansion). The standard model purports no physical center to the universe; rather it support a dimensional centricity for the evolutionary expansion of our SpaceTime continuum.
While the Big Bang model is well established in cosmology, it is likely to be refined in the future. While the known universe provides some glimpse about the earliest moments of the universe, the equations of classical general relativity indicate a dimensional instability (or singularity) for the origin of cosmic time. Moreover, general relativity must break down before the Universe reaches the Planck temperature, and a more accurate assessment of quantum gravity may avoid the conclusion for a singularity.
What is the big bang in religious studies?
the big bang is a theory in science & history of it
just like Freud evulotion theory
all religions like Islam,Christianity & judism believe in one God "the creator"
How do you bang your friends mom?
-You don't -You should be of legal age, she should be legally single or divorced or not in a current relationship
According to the big bang theory what did the universe originate as?
Answer 1
It has been around since God created it. Its not gazillions of years old. Dont believe that crud. It all a lie. The universe has no real creation date. Please read The Bible, it will help open your eyes to so much knowledge. I'm not begging, just a suggestion to the reader.
Answer 2
The latest astronomical data shows the universe to be around 13.7 billion years old.
How does the evidence of the wmap and COBE support the big bang theory?
The work provided even more additional evidence to support the Big Bang theory of the universe.
It was also regarded as the starting point for cosmologyas a precision science.
How did the big bang theory impact society?
If Earth was further away from the Sun we would freeze to death. If Earth was closer to the Sun we would burn to death.
What happens when you have a big vacuum leak?
When you have a big vacuunm leak your car is not going you be able to suck the gas it needs into the intake because, the air it needs to do that, is coming from somewhere other than the throttle bore. So to stay running, the choke will have to be partially closed to help suck more gas down the intake. I know this because I asked the question yesterday and found out for myself today by trial and error!
Who plays Lenard in the Big Bang theory?
In "The Big Bang Theory," the character Leonard Hofstadter is portrayed by actor Johnny Galecki. Leonard is a physicist with a warm personality, often serving as the voice of reason among his group of friends. His character is known for his on-again, off-again relationship with Penny, which is a central theme throughout the series. Galecki's performance contributed significantly to the show's popularity and success.
You think that it should be looked at in more ways and see what was created in the big bang theory?
i think that you are right on that one they should see what was created in the big bang theroy
What sort of radiation suggested evidence for the Big Bang?
The existence, isotropy, and spectrum of the cosmic microwave background radiation (cmbr) is extremely easy to explain if Big Bang Cosmology is true; it is impossible to reasonably explain even its existence with any alternate cosmological hypothesis.
What is Big Bang TOP ideal girl type?
T.O.P said that he did not have a specific ideal woman, but wants her match herself to him, realistic and directing him to good paths and also wants to learn from her. She needs to be mannerly and respectful towards the adults.
The big bang theory states that all matter was once?
Far denser -- almost infinitely more dense -- than it is today.
It is a mistake to say that the BB claims that our entire Universe was once the size of a proton. That statement only applies to what is now the VISIBLE universe -- that small sub-set of our Universe that we can now see. While this 93 billion light year diameter ball is pretty large, it is impossible to determine how much more of our Universe is out there, beyond our present ability to see -- the total amount could be infinite. Thus, instead of saying our entire Universe was much SMALLER than it is today, it is more correct to say it was much DENSER.
What are peices of evidence for the big bang therory?
You may want to check the Wikipedia article on the Big Bang, or science videos on YouTube, for more details; but briefly, the evidence is as follows:* According to calculations based on General Relativity, the Universe can't remain static for long - it must needs expand or contract eventually.
* Similarly, the Second Law of Thermodynamics doesn't allow a static Universe. Entropy increases; there are irreversible processes.
* The redshift of distant galaxies. The only reasonable explanation of this redshift is that the galaxies are moving away from us. This is related to,but not exactly the same, as the Doppler effect.
* The mix of elements and isotopes in the current stage of the Universe closely matches theoretical calculations based on the Big Bang.
* The cosmic microwave background radiation closely matches that which is expected from the Big Bang model. It is a remnant of the time when the Universe cooled below about 3000 K.
Missy on "The Big Bang Theory" is played by actress Amanda Walsh. She appears in the episode titled "The Maternal Capacitance" during Season 2, where she is introduced as Sheldon Cooper's twin sister.
Which best describes the make-up of the object that exploded during the big bang?
A ball of extremely dense, hot, and massive material
What is the initial state of the universe according to the big bang theory?
Very small, very dense, very hot. Basically, all the matter that is currently in the Universe was initially concentrated in a space smaller than an atom.
