Olbers' paradox Astr.|ˈɒlbəz|
[named after H. W. M. Olbers (1758–1840), German astronomer, who propounded it in Astron. Jahrb. (1826) 110.]
The paradox that if stars were distributed evenly (in sufficient numbers) throughout an infinite static universe, the sky should be as bright at night as in the daytime, owing to the fact that whilst the apparent brightness of individual stars decreases with distance the number of stars increases in the same proportion.
1952H. Bondi Cosmol. iii. 23 Olbers' paradox does not arise in a static universe in which, roughly speaking, the stars did not start to radiate until some moment which can be determined..to have been between 108 and 1010 years ago. 1969Rosser & McCulloch Relativity & High Energy Physics vi. 131 Olbers' paradox can be resolved by the fact that the distant stars..are going away from the earth at high speeds (the expanding universe). |
