select the correct answer. which occurrence would contradict the big bang theory? a. over time, distant galaxies move progressively closer to earth. b. a scientist discovers a black hole outside the milky way galaxy. c. the average temperature of the universe decreases. d. a scientist discovers a planet that is about 10 million years old.

Answer

Brief Explanations:

The Big - Bang theory posits that the universe is expanding. Galaxies should be moving away from each other and from Earth over time. Option A, where distant galaxies move progressively closer to Earth, contradicts the idea of the universe's expansion. Option B about black - hole discovery is not in conflict with the Big - Bang theory. Option C, the decrease in the average temperature of the universe, is consistent with the cooling that occurs as the universe expands. Option D, the discovery of a 10 - million - year - old planet, does not conflict with the Big - Bang theory as the universe is much older and planets can form at different times.

Answer:

A. Over time, distant galaxies move progressively closer to Earth.
