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' paradox (the "dark-night-sky paradox") was described by Thomas Digges in the 16th century, by Johannes Kepler in the 17th century (1610), by Edmond Halley and by Jean-Philippe de Chéseaux in the 18th century, by Heinrich Wilhelm Matthias Olbers in the 19th century (1823), and definitively by Lord Kelvin in the 20th century (1901); some ...
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 .
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 .
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 ...
I think it should menition this as it is an obvious question. Could just copy over the relevant section of the Olber's paradox article: Olbers' paradox#Steady_state There is an answer but it is not so immediately obvious that you can expect the reader to see it immediately and not even ask the question.
Why the night sky and space are black – Olbers' paradox The fact that outer space is black is sometimes called Olbers' paradox . In theory, because the universe is full of stars, and is believed to be infinitely large, it would be expected that the light of an infinite number of stars would be enough to brilliantly light the whole universe ...
The infinitely dense gravitational singularity found as time approaches an initial point in the Big Bang universe is an example of a physical paradox.. A common paradox occurs with mathematical idealizations such as point sources which describe physical phenomena well at distant or global scales but break down at the point itself.
