What is the difference between cosmic background radiation and red shift?

Answer 1

Cosmic background radiation is the rediation permeating our universe and originatad at the moment of the Big Bang. Red Shift refers to a phenomenon where radiation detected by an observer can have a different frequency compared to the original emitted by a moving object.

At the moment of the Big Bang, apart for many other things, radiation was emitted at very high frequency. After billion of billion of years this radiation has filled the space and also reduced its frequency (if I remember correctly it should be now in the microwave range).

Immagine a lake of perfectly calm and still water; you throw a stone (...a kind of Big Bang) and then you'll have waves propagating on the entire surface of the lake causing a permanent oscillatory background.

Answer 2

The faint glow of microwaves left over from the Big Bang is known as cosmic background radiation. Redshift, on the other hand, is the phenomenon where light from far-off galaxies appears redder because of the universe's expansion, indicating that those galaxies are moving away from us.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
