Olbers's paradox says that because the night sky is dark, at least one of these three assumptions must be false. Olbers's paradox , also known as the dark night paradox or Olbers and Cheseaux's paradox , is an argument in astrophysics and physical cosmology that says the darkness of the night sky conflicts with the assumption of an infinite and ...
Olbers monument in Bremen by Carl Johann Steinhäuser (1850) Heinrich Wilhelm Matthias Olbers (/ ˈ ɔː l b ər z /; German:; 11 October 1758 – 2 March 1840) was a German astronomer. He found a convenient method of calculating the orbit of comets, and in 1802 and 1807, discovered the second and the fourth asteroids Pallas and Vesta.
Olbers' paradox: Why is the night sky dark if there is an infinity of stars, covering every part of the celestial sphere? GZK paradox : Extreme-energy cosmic rays (like the Oh-My-God particle and several others after it) have been observed that seem to violate the Greisen–Zatsepin–Kuzmin limit , which is a consequence of special relativity .
The expansion of space summarized by the Big Bang interpretation of Hubble's law is relevant to the old conundrum known as Olbers' paradox: If the universe were infinite in size, static, and filled with a uniform distribution of stars, then every line of sight in the sky would end on a star, and the sky would be as bright as the surface of a ...
In modern physical cosmology, the cosmological principle is the notion that the spatial distribution of matter in the universe is uniformly isotropic and homogeneous when viewed on a large enough scale, since the forces are expected to act equally throughout the universe on a large scale, and should, therefore, produce no observable inequalities in the large-scale structuring over the course ...

Steady State theory → – In scientific terms, a scientific theory is an established explanation of an aspect of the natural world; this particular explanation was rejected, so it is not a scientific theory but a scientific model. Throughout this article, its name is inconsistently showed as "theory" and "model".
