Olbers's Paradox states that if the universe were infinitely large and infinitely old, then the night sky would be bright due to the light from an infinite number of stars in every direction. However, this paradox is solved in part by the fact that the universe is not infinitely old, meaning that not all of the light from faraway stars has had enough time to reach us, and that the universe is not infinitely large, meaning that the light from distant stars eventually fades away due to the expansion of the universe. Olbers's Paradox states that if the universe were infinite in size and age, the night sky should be as bright as the surface of the Sun due to the infinite number of stars. However, the fact that the universe is finite in both size and age means that only a finite number of stars and galaxies exist and that their light has not had enough time to reach us from the edges of the observable universe, thereby solving the paradox.
