Olbers' paradox

Pronunciation: /ˌōlbərz ˈperədäks/


The apparent paradox that if stars are distributed evenly throughout an infinite universe of infinite age, the night sky should display a uniform glow, since every line of sight would terminate at a star. But with an expanding universe of finite age, visible light from very distant stars has not reached the Earth.


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