It is the theory that the current universe started with a "big bang". To understand how the theory arose, it has been observed that the universe is expanding. If you imagine time going backwards, then the further back you go, the smaller the universe gets, at some point the universe is so small it is a singularity.
The big bang theory predicted that there would be a background noise from the explosion still detectible in deep space; the noise was detected - in fact, it's a problem in radio astronomy that there is always noise present.

∙ 15y agoThe universe exists. This existence must have had a first cause, and therefore could not be infinite; the universe must have a beginning. Some cause, self-sufficient and not brought about by any other cause, must exist. interaction of somehow uncaused particles that were somehow in uncaused motion through somehow uncaused forces created an event which began the universe as we know it. This is called the Big Bang theory, and many, many questions still remain pertaining to the questions of the origin of the universe.

∙ 6y agoThis is based (among other things) on the observable evidence that the Universe is expanding.
The basic idea is that everything in the observable Universe (which has a radius of about 46 billion light-years) started closely together, some 13.8 billion years ago, in a space smaller than an atom, and in an extremely dense and hot state. From there it expanded, and continues to expand today; after some time, stars and galaxies started forming. I suggest you read a more detailed explanation, as well as a timeline of different events, for example, in the Wikipedia article on "Big Bang".

Which best describes the beginning of big bang theory?
massive energy created matterTo get to the theory ... the red shift (and Hubble).If you're referring to how the big bang began, science has no answer.

How is the big bang theory is an example od scienctific theory?
Hello i am minakshi answer is that the big bang theory is an example of old scientific theory as big bang theory explains that there was an explosion but the isotropy and the homogenity of the universe is not explained by big bang theory to explain his we connect inflatation theory with big bang theory to explain it so the big bang theory is also an example of old scientific theory.
In the big bang theory what describes a universe that will stop expanding and begin to contract?
A closed Universe.

What is the natural big bang theory?
I know of no such reference for a "natural" Big Bang Theory. Must be just another way of referring to the Big Bang Theory with a differing focus (i.e. kind of like the Hot Big Bang Theory).
