Final answer:
Olbers' paradox questions the darkness of the night sky despite the infinity of stars. The commonly accepted solution is the expansion and redshifting of light in the evolving universe.
Step-by-step explanation:
Olbers' paradox is a concept in astrophysics that questions why the night sky appears dark despite the universe being infinite and filled with stars. The paradox suggests that if the universe is indeed infinite and every line of sight eventually falls on a star's surface, then the entire sky should be illuminated.
The commonly accepted solution to this paradox is the evolving nature of the universe. It is believed that the universe is expanding, which means that the light from many distant stars has not reached us yet, resulting in a dark sky. Additionally, the light from distant stars gets redshifted, which decreases its energy and makes it harder to detect.
