which is one piece of information that astronomers use to calculate the age of the universe?\no dark energy\no the age of rocks on earth\no the current motion of inner planets\no patterns of background radiation

Answer

Answer:

D. patterns of background radiation

Brief Explanations:

Cosmic - microwave background radiation patterns provide key data for calculating the universe's age. Dark energy affects expansion rate but not directly age - calculation. Earth rocks' age is much younger than the universe. Inner planets' motion is not related to the universe's age determination.
