the solution to olbers paradox suggests that it gets dark at night because
the universe is not infinite in age
the universe is accelerating
the universe is closed
the universe is flat
the universe is isotropic

Explanation:

Olbers' paradox asks why the night sky is dark if the universe is infinite and filled with stars. The key solution is that the universe has a finite age (~13.8 billion years), so light from stars beyond the observable universe (whose light hasn’t had time to reach Earth) can’t illuminate the night sky. Other options (acceleration, closed/flat geometry, isotropy) don’t directly explain the darkness at night.

Answer:

A. the universe is not infinite in age
