Was They Really..A Big.. Bang?

Question

Was they really a big bang.. I want to know.. i mean.. well.. was the world created by a big bang or not.. please tell me!!

Answer 1

Well, the whole Universe is expanding, suggesting that everything was much smaller and denser at some point.

Also, there's a constant microwave radiation across the whole of the Universe. The only explanation I know for this is that it is the "echo" of the Big Bang. There's got to be many other things that contribute to the theory of the Big Bang, just look around on the Internet.

Answer 2

answering that question is really difficult....from the data that was collected from various satellites, it suggests that Big Bang may have occurred. Then the question arises what caused the big bang - well people think that it may have been caused by two parallel universes in the 11th dimension colliding....sounds freaky yeah? well...i guess the universe itself is freaky lol. astrophysicists all around the world are trying to come to a definite conclusion about how the universe was created...so good question =D

Answer 3

The big bang is currently still only a theory, although ppl talk about it as if it is fact.

There is an excellent book about this called the Collapse of Evolution by Scott Huse.

Well worth reading if you want to make an informed decision.

Answer 4

There is certainly a lot of evidence to support the Big Bang - the redshift of distant galaxies, the existence of cosmic background radiation and so on. This all points to an expanding universe that, at a point some 13.7 billion years ago, was condensed and very energetic. In fact we can be pretty sure about what was happening up to 10^-43 seconds after the start of the universe. There's certainly a lot of misunderstanding about what the Big Bang explains though; it was not an "explosion" as we are familiar with, but a rapid expansion (the term "Big Bang" was coined by Fred Hoyle, who disagreed with the early theory, in order to ridicule it, but the term stuck). The "only a theory" protest misunderstands what is meant by a scientific theory - it's not a "guess", but a well-supported model that best explains the observed facts and evidence (if it was currently unsupported by evidence, it would be a "hypothesis"). And it doesn't go any way to explaining the origin of the singularity that became the universe, just what happened to it (the origin of the singularity and the reason for its sudden expansion are related areas of study which are far more hypothetical).

However, the Big Bang did not directly create the Earth; that was the result of a large cloud of dust and gases condensing into the solar system through electrostatic and gravitational forces.

Answer 5

The Big Bang Theory is the only viable explanation for thousands of astronomical observations.

We can, in effect, actully see the Big Bang.  Since the speed of light is finite, when you look out over long distances, you look back in time.  If you look out 13.7 billion lightyears, you see the Cosmic Microwave Background radiation (at radio wavelengths) surrounding us in all directions.  This radiation originates very early in the Big Bang, as a direct result of the Big Bang.

Answer 6

big bang is only a theory.even science is struggling to find out how the earth or the entire universe was created. a THEORY is just a something that is not proven. and big bang is a theory though science also gives more consideration to this.

it is still unknown, how the universe was created. i guess that is beyond our knowledge. i'm a truth seeker but i guess i'll be contented that universe exists in one way or the other.

Answer 7

Absolutely not. The Big Bang theory has no legitimate proof. It is mind-boggling to imagine the universe "exploding into existence"

Answer 8

the bing bang was the one-point-maximum density-space. i.e.: the univers is like a point, where the density of the matter is infinite. in a femto-second the matter left the point and make the universe. in few second the universe undergo an infative expansion, and the collapse of the neutron and the proton. that made the universe like one know it.

ps sorry for my bad english. i'm italian!

Answer 9

The Big Bang theory was suggested after seeing the Red shift of galaxies around us and Hubble's model of the universal expansion.

Including information from modern particle science and Einsteins works, it was suggested that the universe started in one point and space expands by some sort of strange energy.

Further more the theory predicted that the universe was opaque to radiation until cooling down to about 3000 Kelvin.

This theory predicted that there must by a red-shifted background radiation, which is equal to a 3000 Kelvin (or 3k(ilo) Kelvin) hot blackbody radiation. A few years after the theory was formulated, this radiation was indeed found and is today the most important evidence for the theory of the Big Bang, as well as also the most important factor for further research. Small differences in the strength and "temperature" of the radiation allow scientists to draw conclusions on the early structure of the universe, when it was still only a few million light years across.

But: It was no bang - i doubt there was much to be heard in the moment as there was no matter to transport the sound. ;)

On theories: A theory is no guess. If somebody wants to tell you that, he has not understood what a theory is. A theory is only a model, which take observations you have (redshift of galaxies) and formulates a possible explanation (Big Bang) and further more (and that is important for ANY theory) makes predictions what else can be observed for testing the theory (Background radiation).

A theory is never the end of all research, and it is never intended to be so. Galileo's theory of gravity is still useful (all objects fall on Earth at the same speed), though Newtons Theory of gravity explains observations which Galileo did not know at that time. And Einsteins general relativity explains phenomena of gravity, Newton did not know when he made his theory - still you can happily use Newtons gravity model for 99% of all things around you with only minimal errors.

A theory can be wrong and that is intentional. A model, which can't be wrong, is a called a tautology and is actually closer the observations, than to a scientific theory. because of that, it is important in science to test theories. All the time. The better you test the theory, the more confidence you can have in it.

So it is with the Big Bang - it was tested very often, with observations and experiments in particle accelerators and the original theory is already surpassed by better theories, which are more accurate (Superinflation).

A theory is not an answer, it is a new question. ;)

Answer 10

Well yeah, there was a really big bang...

Answer 11

There was, and still are Big Bangs going on. and will be till  the end of time,

Answer 12

If it didn't, I've wasted the whole of my working life!  I am an astronomer, working in the field of cosmology, and I believe that we have got it pretty much right.  Doubtless, we will modify it over time (that's what I am trying to do), maybe substantially, but in essence, the origins of the Universe in the Big Bang is now established to within several hundred decimal places.
