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, described by him in 1823 (and then reformulated in 1826), states that the darkness of the night sky conflicts with the supposition of an infinite and eternal static universe. In July 1804, the young Friedrich Wilhelm Bessel contacted Olbers to get his opinion of Bessel's treatise on orbit calculation of Halley's Comet .
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 .
A question related to the problem of personal identity is Benj Hellie's vertiginous question. The vertiginous question asks why, of all the subjects of experience out there, this one—the one corresponding to the human being referred to as Benj Hellie—is the one whose experiences are live?
However, modern astronomers supply reasonable explanations to answer this question. One of at least several explanations is that distant stars and galaxies are red shifted, which weakens their apparent light and makes the night sky dark. [6] However, the weakening is not sufficient to actually explain Olbers' paradox.
1720 – Edmund Halley puts forth an early form of Olbers' paradox (if the universe is infinite, every line of sight would end at a star, thus the night sky would be entirely bright). 1729 – James Bradley discovers the aberration of light , which proved the Earth's motion around the Sun, [ 72 ] and also provides a more accurate method to ...
To me, one of the strongest arguments against the Steady State theory has always been Olber's Paradox. The Big Bang answers it quite neatly. Should I mention it in the article? Jhobson1 10:52, 26 May 2007 (UTC) No, because it is not true. See Olber's article - explained by the redshift. --Michael C. Price talk 21:30, 16 August 2007 (UTC)
The mathematically formulated paradox of Olbers is reformulated here as a process of ever more shells becoming visible, one on top of the other, in doing so creating a sphere of increasing radius full of stars. However, what Olbers did not take into account is the disappearing again of shells because the stars in it had died and the light they ...
