Olbers's Paradox: Let there be n stars per unit volume througho... | Filo

(From Olbers's paradox.) Assume a static universe in which the stars are uniformly distributed. Divide all space into shells of constant thickness: the stars in any one shell by themselves subtend a solid angle of ω0. Allowing for the blocking out of distant stars by nearer stars, show that the total net solid angle subtended by all stars, shells extending to infinity, is exactly 4 π. (Therefore the night sky should be ablaze with light.) | Numerade
