Question

which of the following pieces of evidence supports the big bang theory? a red shift of distant galaxies shows the universe is currently contracting b red shift of distant galaxies shows the universe is currently expanding c blue shift of distant galaxies shows the universe is currently expanding d blue shift of distant galaxies shows the universe is currently contracting

Explanation:

The Big - Bang theory posits that the universe is expanding. Red - shift occurs when an object is moving away from an observer, and the red - shift of distant galaxies indicates that they are moving away from us, which supports the idea of the universe's expansion. Blue - shift occurs when an object is moving towards an observer.

Answer:

B. Red Shift of distant galaxies shows the universe is currently expanding
