Olbers' paradox states that if the universe is infinite in age and size, then every line of sight should eventually end on a star, making the entire sky bright with starlight. Therefore, the fact that the sky is dark at night suggests that either the universe is finite in size or finite in age, and therefore not enough time has passed for all the starlight to have reached us. This paradox led to the realization that the universe must have a finite age.
