1. Redshift of Galaxies
The redshift of distant galaxies means that the Universe is probably expanding. If we then go back far enough in time, everything must have been squashed together into a tiny dot. The rapid eruption from this tiny dot was the Big Bang.
2. Microwave Background
Very early in its history, the whole Universe was very hot. As it expanded, this heat left behind a "glow" that fills the entire Universe. The Big Bang theory not only predicts that this glow should exist, but that it should be visible as microwaves - part of the Electromagnetic Spectrum.
This is the Cosmic Microwave Background which has been accurately measured by orbiting detectors, and is very good evidence that the Big Bang theory is correct.
3. Mixture of Elements
As the Universe expanded and cooled down, some of the elements that we see today were created. The Big Bang theory predicts how much of each element should have been made in the early universe, and what we see in very distant galaxies and old stars is just right.
You cannot look in new stars, like the Sun, for this evidence, because they contain elements that were created in previous generations of stars. As such, the composition of new stars will be very different from the composition of stars that existed 7 billion years ago, shortly after the Big Bang.
4. Looking back in time
The main alternative to the Big Bang theory of the Universe is called the Steady State theory. In this theory, the Universe does not change very much with time.
Remember that because light takes a long time to travel across the Universe, when we look at very distant galaxies, we are also looking back in time.
From this we can see that galaxies a long time ago were quite different from those today, showing that the Universe has changed. This fits better with the Big Bang theory than the Steady State 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.
The duration of The Big Bang Theory is -1320.0 seconds.
The Big Bang is the theory that was developed to describe the origins of the universe.
No
It is similar to the Big Bang theory. The ekpyrotic theory is, a theory that their is a parallel universe (More than one) In our universe.

One can learn about the Big Bang theory that explains how the universe was created from a number of sources. For instance, the Big Bang theory is discussed in numerous science blogs, How Stuff Works, and Curious Astronomy.

the big bang theory
The Big Bang Theory is set in Pasadena California.
The duration of The Big Bang Theory is -1320.0 seconds.
Big Bang Theory is available for rental only.
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).
The Big Bang is the theory that was developed to describe the origins of the universe.
No. The Big Bang theory came a lot later.
Constellations are components of galaxies and have little to do with the Big Bang Theory.
Penny - The Big Bang Theory - was created in 2007.
