What does red shift blue shift have to do with the big bang?

Answer 1

When a star o r Galaxy moves away from us the the light waves get expanded..So the spectrum have a shift to red end.

The waves are compressed when the object approaches us, causing a shift in the spectrum towards the blue end. The galaxies exhibit a red shift, which is evidence of the big bang theory and the expansion of the universe. The source of the photo is unknown. Taken from a Google search.

Redshift and blueshift are phenomena that are seen in the light that distant galaxies emit; redshift happens when galaxies are moving away from us, while blueshift happens when they are moving towards us. The Big Bang theory states that the universe is expanding, which causes galaxies to move apart. Consequently, the redshift of these galaxies' light supports the Big Bang theory by providing evidence of the universe's expansion.

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.
