Question

[OU.04]In your own words, explain how background noise detected in space provides evidence for the Big Bang Theory.

Answer 1

Firstly, the left over energy in the form of microwaves provides evidence for an expansion of space. Similarly, the structure of the CMBR is uniform with minor fluctuations, this shows how galaxies may have formed as the fluctuations allowed the clumping of mass at these points, increasing gravity and in turn causing more mass to gather together. The CMBR can tell us many things about the universe but only at the point of recombination, when the universe became transparent to photons.

The Big Bang Theory perfectly predicted the CMBR. No other hypothesis can adequately explain the CMBR other than saying.

The key to this question is in the first FOUR words

Go and read about it CMBR is 'Cosmic Microwave Background Radiation' is the 'noise' referred to in the question.

Once you have read and researched it then the key test of you understanding is whether you can explain it IN YOUR OWN WORDS
