By Seth Shostak Astronomer, Project Phoenix posted: 07:01 am ET 25 October 2001 Is there obvious proof that we could be alone in the Galaxy? Enrico Fermi thought so and he was a pretty smart guy. Might he have been right? It's been a hundred years since Fermi, an icon of physics, was born (and nearly a half-century since he died). He's best remembered for building a working atomic reactor in a squash court. But in 1950, Fermi made a seemingly innocuous lunchtime remark that has caught and held the attention of every SETI researcher since. (How many luncheon quips have you made with similar consequence?) The remark came while Fermi was discussing with his mealtime mates the possibility that many sophisticated societies populate the Galaxy. They thought it reasonable to assume that we have a lot of cosmic company. But somewhere between one sentence and the next, Fermi's supple brain realized that if this was true, it implied something profound. If there are really a lot of alien societies, then some of them might have spread out. Fermi realized that any civilization with a modest amount of rocket technology and an immodest amount of imperial incentive could rapidly colonize the entire Galaxy. Within ten million years, every star system could be brought under the wing of empire. Ten million years may sound long, but in fact it's quite short compared with the age of the Galaxy, which is roughly ten

If even a very small fraction of these have planets which develop technological civilizations, there must be a very large number of such civilizations. If any of these civilizations produce cultures which colonize over interstellar distances, even at a small fraction of the speed of light, the galaxy should have been completely colonized in no more than a few million years [1]. Since the galaxy is billions of years old, Earth should have been visited and colonized long ago. The absence of any evidence for such visits is the Fermi paradox.

Fermi paradox From Wikipedia, the free encyclopedia Jump to: navigation search This article is about the absence of evidence for extraterrestrial intelligence. For the type of estimation problem, see Fermi problem . For the music album, see Fermi Paradox (album) A graphical representation of the Arecibo message — Humanity's first attempt to use radio waves to actively communicate its existence to alien civilizations The Fermi paradox is the apparent contradiction between high estimates of the probability of the existence of extraterrestrial civilizations and the lack of evidence for, or contact with, such civilizations. The age of the universe and its vast number of stars suggest that if the Earth is typical, extraterrestrial life should be common. In an informal discussion in 1950, the physicist Enrico Fermi questioned why, if a multitude of advanced extraterrestrial civilizations exist in the Milky Way galaxy , evidence such as spacecraft or probes is not seen. A more detailed examination of the implications of the topic began with a paper by Michael H. Hart

Please Read How You Can Help Keep the Encyclopedia Free Sorites Paradox First published Fri Jan 17, 1997; substantive revision Mon Aug 15, 2005 This phenomenon at the heart of the paradox is now recognised as the phenomenon of vagueness (see the entry on vagueness ). Once identified, vagueness can be seen to be a feature of syntactic categories other than predicates, nonetheless one speaks primarily of the vagueness of predicates. Names, adjectives, adverbs and so on are only susceptible to paradoxical sorites reasoning in a derivative sense. Sorites arguments of the paradoxical form are to be distinguished from multi-premise syllogisms (polysyllogisms) which are sometimes also referred to as sorites arguments. Whilst both polysyllogisms and sorites paradoxes are chain-arguments, the former need not be paradoxical in nature and the latter need not be syllogistic in form. 1. The Sorites In History 2.

One, seeing herself thirty years in the future would put Jennifer into shock and she'd simply pass out. Or two, the encounter could create a time paradox. The results of which could cause a chain reaction that would unravel the very fabric of the space-time continuum and destroy the entire universe!... Granted, that's the worst-case scenario. The destruction however might be limited merely to our own galaxy. Marty Well that's a relief! A paradox , in time travel, is "a situation in which the effect of an incident contradicts or eliminates the cause of that same incident" The classic example of this is the " Grandfather Paradox ". An example of this would be in which a person travels back in time, kills his/her grandfather. This results in the erasing of his/her own existence and raises the question, if he never existed, how could he travel back in time to kill his/her grandfather? According to Doc Brown , a paradox could ultimately unravel the very fabric the space-time continuum and destroy the entire universe (or at least the Milky Way galaxy) and had to be avoided.

Please Read How You Can Help Keep the Encyclopedia Free Curry's Paradox First published Wed Jan 10, 2001; substantive revision Wed Feb 13, 2008 Russell's paradox , Curry's paradox challenges familiar naive theories, including naive truth theory (unrestricted T-schema) and naive set theory (unrestricted axiom of abstraction), respectively. If one accepts naive truth theory (or naive set theory), then Curry's paradox becomes a direct challenge to one's theory of logical implication or entailment. Unlike the liar and Russell paradoxes Curry's paradox is negation-free; it may be generated irrespective of one's theory of negation. An intuitive version of the paradox runs as follows. Tasmanian devils have strong jaws. The second sentence on The List is circular. If the third sentence on The List is true, then every sentence is true. The List comprises exactly four sentences. Although The List itself is not paradoxical, the third sentence (a conditional) is. Is it true? Well, suppose, for conditional proof, that its antecedent is true. Then the third sentence of The List is true is true. Since the third sentence of The List is `If the third sentence of The List is true, then every sentence is true', substitution (of identity) yields that

Paradox From Wikipedia, the free encyclopedia Jump to: navigation search Robert Boyle 's self-flowing flask fills itself in this picture, but perpetual motion machines cannot exist. A paradox is a sentence in logic that cannot be true but also cannot be false . Many famous problems of this kind exist. One of most famous paradoxes is called the liar's paradox . It is the simple sentence "This sentence is a lie If the sentence is true, then it is a lie, as it says. But if it is a lie, how can it be true? A lie cannot also be the truth . So the sentence being true makes it a lie. If the sentence is a lie, then it is not as it says, it is true. But that is just what the sentence says. So that makes it true. So the sentence being a lie makes it true. This paradox is not just true in English but in any language powerful enough for a sentence to make a claim about itself. This is true of mathematics as well. Paradox can never be removed from any symbol system that makes claims about itself. Another example is the statement that there is no cabal . Only a cabal can know if there is no cabal, so this is either a guess, or, it is a cabal trying to pretend it does not exist.
