what is the big bang? is it realy true?

Answer 1

hi

Answer 2

More recent calculations indicate that hydrogen and helium would have been the primary products of the big bang, with heavier elements being produced later. Gamow's theory, however, provided a basis for understanding the earliest stages of the universe and its subsequent evolution. The extremely high density within the primeval atom would cause the universe to expand rapidly. As it expanded, the hydrogen and helium would cool and condense into stars and galaxies. This explains the expansion of the universe and the physical basis of Hubble's law
As the universe expanded, the residual radiation from the big bang would continue to cool, until now it should be a temperature of about 3 degrees Kelvin. Another major breakthrough occurred in 1965 completely by accident. Two physicists who were trying to refine a radio receiving device, found they couldn't eliminate an unknown source of noise that corresponded to a temperature of about 3 degrees Kelvin. No matter where they pointed the receiver in the sky, this level of radiation remained constant. What they had unknowingly uncovered was the lingering effects, or the microwave radiation of the giant explosion from which the universe was formed. The discovery of this relic radiation provided what most astronomers consider to be the earliest confirmation of the big bang theory. In 1983, astrophysicist Fred Hoyle was the first to coin the expression, "The Big Bang Theory"but it was not until that famous day in 1992 that scientists obtained the evidence they needed to conclusively prove that the Big Bang took place.

Today the Big Bang Theory is the most broadly accepted theory for the origin and evolution of our universe. It postulates that the observable universe started from an instantaneously expanding point and that since then the universe has continued to expand, gradually increasing the distance between our Galaxy and external galaxies

Answer 3

The Big Bang is the theory proposed by George Gamow and Begian priest Abbe Georges Lemaitre, also called the "theory of the universe". It states that the universe started when all matter, including dust particles were sucked up by a strong gravitational force and that force was so tremendous it exploded.

When it exploded, all kinds of materials were flying in different direction thus producing the planets, stars and other celestial bodies. It is also assosiated with the Big Crunch or the Gnab Gib (Big Bang spelled backwards) which states that the Universe will come to a time that it expanded too much so it once again became drawn to the center and collapsed.

It is not yet scientifically proven because there is no known way of proving it through experimentation.Of course, with the help of technology, science will find its way to either prove or disprove this theory.Scientists say that is the most scientific way to prove the start of the universe which was billions of years ago,but of course the religious believe that there is one Supreme Creator that created the Universe, including ourselves.


Hope it helped.

Answer 4

In physical cosmology, the Big Bang is the scientific theory of how the universe emerged from a tremendously dense and hot state about 13.7 billion years ago. The theory is based on the observations indicating the expansion of space as indicated by the Hubble redshift of distant galaxies taken together with the cosmological principle.

Extrapolated into the past, these observations show that the universe has expanded from a state in which all the matter and energy in the universe was at an immense temperature and density. Physicists do not widely agree on what happened before this, although general relativity predicts a gravitational singularity.

Answer 5

Did the 'big bang' really happen?..The evidence is yes it did!..The first evidence for this was discovered in the late 60's when the predicted 3.6 degree background microwave radiation was found!..The universe is constantly expanding somewhat similiar to dots painted on a ballon being inflated, each dot representing a galaxy, Why is it expanding at an ever increasing rate? why are galaxys clumping together?..There aint enough room here to answer all that!..Suffice it to say, that there was a 'primordial particle' which went "bang" about 15 million <> years ago is supported by what can now be observed within the physics of the universe, either visually or within predicted theory!..

Answer 6

I can't answer this correctly because I wasn't there when the world was born.
However as our pea brains need to connect all that is around us into what we call catagories then why not have the big bang.
Our known usniverse is, it exists and that is the beauty of our World. Where id Adam and Eve come from The big bang? I don't want an answer yet you can see where I amcoming from.

Answer 7

the big bang is where the universe was created in a blast sending matter in all directions. this is still considered to be true by most scientist. however, the "big crunch" where gravity wins and pulls all matter back together is not true. galaxies are thought to be moving away at faster speeds. therefore, in about couple hundred billiion years there will be a blank and dark universe.

Answer 8

the big bang theory is that is to state that few million tears ago some explosion might have been happened so that this universe is evolved i think this is the only possibility that happened
