Olbers' paradox

Pronunciation: /ˈɒlbəz/

noun

Astronomy
The apparent paradox that if stars are distributed evenly throughout an infinite universe, the sky should be as bright by night as by day, since more distant stars would be fainter but more numerous. This is not the case because the universe is of finite age, and the light from the more distant stars is dimmed because they are receding from the observer as the universe expands.

Origin

1950s: named after Heinrich W. M. Olbers (1758–1840), the German astronomer who propounded it in 1826.
