Question

The night sky is dark because the universe is neither static nor infinitely old.

A) True
B) False

Answer 1

According to Olbers's paradox, the night sky is dark because the universe is neither static nor infinitely old. The commonly accepted evolution of the universe as a solution to this paradox is that the universe is expanding, causing the light from distant stars to redshift and become less visible to us.

Step-by-step explanation:

The night sky is dark because the universe is neither static nor infinitely old. This is true. According to Olbers's paradox, if the universe is infinite and has existed for an infinite amount of time, then any line of sight should eventually fall on a star's surface. However, the sky is dark at night, which indicates that the universe is neither static nor infinitely old. The commonly accepted evolution of the universe as a solution to this paradox is that the universe is expanding, causing the light from distant stars to redshift and become less visible to us.
