what is the meaning of (the big bang)?

Answer 1

In physical cosmology, the Big Bang is the scientific theory that 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 (in accord with the Robertson-Walker model of general relativity) 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 (for reporting on some of the more notable speculation on this issue, see cosmogony).

The term Big Bang is used both in a narrow sense to refer to a point in time when the observed expansion of the universe (Hubble's law) began — calculated to be 13.7 billion (1.37 × 1010) years ago (±2%) — and in a more general sense to refer to the prevailing cosmological paradigm explaining the origin and expansion of the universe, as well as the composition of primordial matter through nucleosynthesis as predicted by the Alpher-Bethe-Gamow theory.

From this model, George Gamow in 1948 was able to predict, at least qualitatively, the existence of cosmic microwave background radiation (CMB). The CMB was discovered in 1964 and further corroborated the Big Bang theory, giving it an additional advantage over its chief rival, the steady state theory.

Answer 2

As far as I know, the Big Bang is still a hypothesis, although a very convincing one judging from all the evidence. It hasn't quite attained the status of being called a fact, however.

Once it is considered factual, then there can be theories about it. The other people answering this question are making the common mistake of confusing a theory with an hypothesis. Scientifically, a theory is an explanation of a set of well-established facts. In the vernacular language, theory means an educated guess - the equivalent of when a scientist uses the word hypothesis.

This word confusion continues to fuel the debate over evolution, when people think they are making a point by saying evolution is "only a theory." Nope, evolution is a fact; the theory is its continually evolving explanation.

Answer 3

The Big Bang Theory is the dominant scientific theory about the origin of the universe. According to the big bang, the universe was created sometime between 10 billion and 20 billion years ago from a cosmic explosion that hurled matter and in all directions.

Answer 4

The "meaning" or implication of the big bang is huge. It means that the universe is not static, but in motion. It also means that there was a beginning! This is a BIG DEAL. It also seems to imply that the universe does not go on forever, but is finite!

These notions have done more to reshape our notions of reality and existence in cosmology and other fields than anything else. Don't be misled by other posters who say there is no meaning, they just don't get it.

Answer 5

if God exists i do no longer think of the super Bang theory exists...except God became on top of problems with the super Bang and created the great universe and time. Which i think of is a suitable theory.

Answer 6

most scientists agree that our universe was created
some 13 or 14 billion years ago by a tremendous
explosion called the "bing bang"
it is only a theory - but there is alot of very strong
evidence that it is fact

Answer 7

There is no "meaning" to it..
Science theorizes that the universe began with the explosive
expansion of a single singularity something like a super concentrated black hole...

Answer 8

All the dirt in the universe was shaped like a ball and it just blew up by itself.

Answer 9

Big bang is a crock of Doo-dooo.

Answer 10

how the world came 2 be today it was suppost to be a small piece of matter that exploded and created the world sorry but i dont believe in that i believe in GOD
