Main points of the big bang:
- Everything started from one small point in space billions of years ago. This tiny space is thought to be smaller than a mm and had all the elements in it. Then there was a big explosion.
- This explosion caused and is still causing the Universe to constantly expand - galaxies are moving further away from each other.
Some evidence for the big bang theory:
Red shift - When wavelength increases and causes light to move towards the red end of the spectrum. The further away an object the greater the red shift.
When you look at objects that contain various elements they absorb certain wavelengths of light in the spectrum; these show as black lines. If you look at a similar object in space that is further away the 'black lines' move towards the red end of the spectrum.
This supports point 1. If you tracked the galaxies back in time they would all go to that point.
CMB (Cosmic Microwave Background Radiation) - was created as high energy gamma radiation just after the big bang. It has been traveling through space since then. As the Universe has expanded, it stretched out to longer and longer wavelengths and is now microwave radiation. It is thought to be the left over heat - a bit like an 'echo' of the big bang.
This supports point 2.

How might the redshift indicate there is evidence for the big bang theory?
The red shift doesn't just indicate that there is evidence for the Big Bang theory: the Hubble red shift is evidence supporting the Big Bang theory.
Is the number of stars in the Milky Way Galaxy evidence in support of Big Bang Cosmology?
no the no. of stars in the milky way is not the evidence in support of the big bang cosmology.
Who gave evidence of the big bang theory?
edwin hubble
How does expanding universe provide evidence for big bang theory?
It is not so much that the universe is expanding, but rather the rationalization for its expansion that provides evidence to support the Big Bang Theory. The Big Bang supports interpreted observational evidence of the Cosmic Microwave Background Radiation (CMBR) barrier that there is an evolutionary expansion of the universe which promotes a finite age for the universe.
How does the evidence of the wmap and COBE support the big bang theory?
The work provided even more additional evidence to support the Big Bang theory of the universe.It was also regarded as the starting point for cosmologyas a precision science.
How might the redshift indicate there is evidence for the big bang theory?
The red shift doesn't just indicate that there is evidence for the Big Bang theory: the Hubble red shift is evidence supporting the Big Bang theory.
Background radiation detected in space is believed to be evidence that?
the big bang occured
What evidence was used to develop the big bang theory?
The red shift and the cosmic microwave background radiation was the evidence used to develop the big bang theory.
Is the number of stars in the Milky Way Galaxy evidence in support of Big Bang Cosmology?
no the no. of stars in the milky way is not the evidence in support of the big bang cosmology.
When will big bang two will happen?
yes it will happen again after the big crunch then of course, the big munch..... At present there is no evidence that another Big Bang will occur.
If God exists why is there no evidence of him And yet there is a mountain of evidence for Evolution and the Big Bang?
He doesn't
Is the red-shift responsible for the big bang theory?
No, it's the other way round. The Big Bang is responsible for the redshift.

Most of the scientific evidence available today supports the?
the big bang theory
Which of these is evidence that supports the big bang theory?
cosmic microwave background radiation
Why was cosmic background radiation an important discovery?
It is important evidence of the Big Bang.
