which is one piece of information that astronomers use to calculate the age of the universe? dark energy the age of rocks on earth the current motion of inner planets patterns of background radiation

Answer

Brief Explanations:

Astronomers use cosmic microwave - background radiation patterns. These patterns provide crucial information about the early universe and are used in calculations related to the age of the universe. Dark energy affects the expansion rate but is not the main direct factor for age calculation. The age of Earth rocks only tells about Earth's history. The motion of inner planets is related to gravitational dynamics and not directly to the age of the universe.

Answer:

D. patterns of background radiation
