Question

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

Explanation:

The Big - Bang theory posits that the universe is expanding. Galaxies should move away from each other over time. Option A, where distant galaxies move closer to Earth, contradicts the idea of an expanding universe. Option B is consistent with current knowledge of the universe having black holes in different galaxies. Option C is in line with the cooling of the universe as it expands. Option D about the age of a planet does not directly conflict with the Big - Bang theory.

Answer:

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