Considering their orbits and those of the other asteroids then known, Olbers concluded that they are fragments of a disrupted planet that had formerly revolved around the sun.
He is best remembered for Olbers' paradox: "Why is the sky dark at night?" Assuming that space is infinite and filled with stars, he suggested, the entire sky should be as bright as the surface of the sun.

Olbers wrote, "If there really are suns throughout the whole of infinite space, and if they are placed at equal distances from one another, or grouped into systems like that of the milky way, their number must be infinite and the whole vault of the heaven will appear as bright as the Sun.
If Olbers' assumptions are correct, at the volume of space containing billions of galaxies, the night sky should be as bright as the surface of the sun.
The accepted modern solution to Olbers' Paradox is that the big bang creates a light horizon and the expansion of space time lowers the light intensity and shifts it into the invisible red spectrum.

The method he developed to figure out the orbit of a comet that he discovered in 1786 became standard in the nineteenth century.
Olbers was also a supporter of pluralism and of the increasingly contentious idea that the Moon was inhabited by intelligent beings (see Moon, life on).
In the same paper in which he presented his famous paradox, he wrote that it is "most highly probable" that "all of infinite space is filled with suns and their retinues of planets and comets."

Heinrich Olbers (1758-1840), een Duitse astronoom, meende een antwoord op deze vraag gevonden te hebben.
Hij veronderstelde dat het, als de dichtbijgelegen delen van het heelal een kenmerkend voorbeeld waren, steeds maar weer herhaald in verafgelegen delen, onmogelijk was dat het heelal oneindig groot zou zijn.
Toch is de nachthemel bepaald donker en dus (volgens Olbers) zou er geen oneindig aantal sterren zijn en zou het heelal begrensd moeten zijn.

 The 3K Microwave Background and the Olbers Paradox
Heinrich Olbers studied the problem of a very large number of stars in the universe.
This paradox can be solved by the fact that a large amount of interstellar matter (dust and gases) have been shown to be at 3 K. Therefore, an observer having his eyes sensitive to the Planck radiation at 3 K would see that the night sky is bright, as expected by Heinrich Olbers.
Naturally Olbers' apparent paradox exists at visible wavelengths because then, that radiation is screened by dark matter.
