Olbers’ paradox

Olbers' paradox

Olbers’ paradox is the argument that the darkness of the night sky conflicts with the assumption of an infinite and eternal static universe. The paradox is commonly attributed to the German amateur astronomer Heinrich Wilhelm Olbers, who described it in 1823. Edward Robert Harrison argues that the first to set out a satisfactory resolution of the paradox was Lord Kelvin.

About Olbers’ paradox in brief

Summary Olbers' paradoxOlbers’ paradox is the argument that the darkness of the night sky conflicts with the assumption of an infinite and eternal static universe. The paradox is commonly attributed to the German amateur astronomer Heinrich Wilhelm Olbers, who described it in 1823. Edward Robert Harrison argues that the first to set out a satisfactory resolution of the paradox was Lord Kelvin, in a little known 1901 paper. Edgar Allan Poe suggested that the finite size of the universe resolves the apparent paradox. More specifically, because the universe is finitely old and the sky would not be infinitely bright, every point in the sky in the universe would still be like the surface of a star, Harrison argues. He also argues that it is still possible for the paradox to hold in a finite universe, though the sky wouldn’t be as bright as it would be if it was infinite and static.
