American Intervention in Soviet-Afghan War Essay

During the Cold War, the United States set out to go after the Soviet Union by agreeing with Afghanistan and taking extraordinary measures to stop Soviet impact and socialist belief system. In 1979, the Soviet Union attacked Afghanistan trying to extend its impact in the Middle East with the nonattendance of American impact. Now exposed War the United States and Soviet Union were pretty much at the peak of their difficulty, so the U. S. accordingly chose to get included by strengthening Afghan’s essential insubordinate gathering, the mujahidin. The United States endangered country security by offering huge help to mujahidin progressives, and in doing so the U. S. helped them obstruct Soviet guideline over Afghanistan. There are a lot of reasons confirming America’s absence of prescience and reasonability, one being that the condition of the Soviet Union was not incredible as it might have been. One should mull over that the Soviet Union was at that point in an extreme decay when the United States started to mediate in Soviet-Afghan undertakings. Benjamin Frankel, a regarded author who composed an article for History in Dispute, depicted how there was a drawn out discussion in the Soviet Union on the subject of how to continue with socialist strategies (14). Furthermore, America previously communicated its firm stance strategy toward the USSR in an increasingly inconvenient manner. In 1983, President Ronald Reagan set up the Strategic Defense Initiative to ensure the U. S. from potential ballistic rocket assaults by the Soviet Union. Altogether, as the ABC-Clio database recommends in section ten of â€Å"Cold War, 1945-1991†, the USSR spent roughly $80 billion on the Soviet-Afghan War. The fall of the USSR was hurried by its grandiose spending on the superfluous reason. Like the financial issues in the Soviet Union, the United States’ activities concerning Soviet-Afghan undertakings delivered extraordinary weights upon the U. S. economy. The United States squandered a generous measure of cash so as to help mujahidin revolts so they could check their Soviet oppressors, yet got no pay consequently. As an obscure creator from Mount Holyoke College gauges in â€Å"Origins of the Taliban†, the United States lost about $3 billion just on financing these undercover operations. The mujahidin and Afghanistan in general gave little consequently. The mujahidin, for one, just utilized America for what it gave and disposed of the nation once exchanges were finished. Likewise, Afghanistan contained lacking regular assets contrasted with its Middle-Eastern partners. Notwithstanding this action’s negative effect on the U. S. economy, it was additionally unjustified by the United States’ disappointment in convincing Afghans to change over to its political perspectives. The United States didn't spread majority rules system or even hinder the Soviet Union’s socialist impact on Afghanistan. Rather than acting how it did, the United States ought to have permitted Afghanistan to develope itself and make sense of its own issues to a degree. One indication of movement in the nation happened in the mid-2000s when Afghanistan held its first presidential political decision. For instance, Canada has profited by having the international strategy of neutrality. Moving back to the mujahidin, Benjamin Frankel portrays it, expressing, â€Å"Once they assisted with pushing the Soviets out of Afghanistan, they directed their concentration toward the abhorred ‘infidel’ West and its ‘satanic’ pioneer, the United States† (16). Benjamin Frankel proceeded to talk about how the Afghans were aloof toward the message of majority rule government, while they previously hated the belief system of socialism (16). These reasons clarify why the two gatherings never became partners and part ways once the Soviets pulled back in 1989. At some point amidst the United States endeavoring to spread popular government in Afghanistan, the Jimmy Carter system passed a ban on wheat and corn against Russia as another endeavor to trouble the Soviet Union. The Russian Grain Embargo, sanctioned in 1980, had a negative money related effect on American ranchers. This demonstration was attracted up to respond the past continuous strains between the United States and Soviet Union which increased when the United States started to help the mujahidin in 1979. Regarding the matter of U. S. what's more, USSR exchange, delegate George McGovern expressed at a 1980 Senate hearing in passage ten on the Annals of American History database that horticultural produce took up 75% of their exchange. With this absence of exchange, the USSR and U. S. each profoundly endured. Because of the Russian Grain Embargo, costs on a bushel of wheat dropped 50? furthermore, costs for a bushel of corn dropped 30?. As McGovern later declares to the senate in his discourse in passage nineteen, anticipated numbers â€Å"do not think about the gigantic increment in cost of creation for crop year 1980 for ranchers, coupled by discouraged markets. † This demonstration, by implication related with rising strains likewise causing the U. S. to strengthen the mujahidin, made live hard for ranchers. The Russian Grain Embargo left an incredible blemish on agrarian culture in both the United States and the Soviet Union, yet moreso in the U. S. This announcement shows the incongruity behind the ban. The damage done to the USSR was considerable, however. One may state that the Russian Grain Embargo went with the firm stance strategy Reagan set forth toward the USSR, however this contention is refuted by the money related weights on America and the Soviet Union. Therefore in his discourse, George McGovern states in section twenty, â€Å"The U. S. omestic hit to the farming network can sensibly be closed to be more noteworthy than the one we are conveying, at any rate over the long haul and in any event in financial terms. † In addition, Russia was falling off a record low year for crop creation, further supporting this act’s injustification. Regardless of the way that the Russian Embargo Act was predominantly a weight to cultivate society, it likewise demonstrated or will have demonstrated to be a weight to other significant pieces of society. The Russian Grain Embargo likewise crushed both the United States and the Soviet Union in manners other than agronomically including regular residents. In passage eighteen McGovern insinuates his incredible measurable information, taking note of that American citizens made up for the obligation of the Russian Grain Embargo by paying an aggregate of $3. 8-5 million. The validity of the United States as a solid exchange accomplice soar because of the ban. The organization of previous President Jimmy Carter presumably didn't anticipate this result or even consider it. Another result of the demonstration was extended group butcher in Russia. Russians subsequently devoured awful or at times unsanitary meat due to the absence of U. S. meat shipments. Rather than burning through our time making superfluous approaches or embargoes or unfoundedly making a ground-breaking Afghan strong power, the Unites States ought to have taken advantage of other significant lucky breaks. For instance, during the period where the United States sent weapons to the mujahidin, Afghanistan’s neighboring nation Pakistan built up an atomic weapon program. This is unexpected on the grounds that constraining atomic weaponry in wherever was clearly expected to be a central worry of America, yet we didn't take care of business. Pakistan could have imparted atomic mysteries to its partner neighbors, hence imperiling American security. Benjamin Frankel expounded on the likelihood that Pakistan could in the end utilize their atomic weapons. All things considered, America would absolutely lament not investing in the issue. Prior to acting, we need to initially contemplate all ramifications †the advantages and disadvantages. Either the different pioneers of the United States from 1979 to 1989 didn't do this or they misevaluated. At the point when a nation is on a nevitable way to its destruction, going through a lot of cash to attempt to rush it is superfluous. Blocking exchange to that nation is inessential and imbecilic if all gatherings included are adversely influenced like on account of the Russian Grain Embargo. At long last, the Unites States and Soviet Union were troubled by their foolhardy methodologies; therefore, we ought to gain from their mix-ups and endeavor to fix any outstanding outcomes. La mentably, we may one day need to persevere through the repercussions of not making a move if a Middle Eastern nation sets off an atomic bomb.

These oxides of carbon are colorless, odorless, carbon dioxide gas is detectable because it forms mist like cloud with clean water. Carbon is non-metal while silicon is a metalloid and lead is a metal, therefore metalloid oxides will form amphoteric oxides. Oxides of lead include lead II oxide, lead IV oxide, and lead VI oxide; PBO which is lead II oxide is a powerful oxidizing agent which is yellow in color and sometimes rhombic. Silicon oxides include silicon dioxide, remember silicon monoxide does not exist, physical properties include high melting point and boiling point but carbon dioxide and lead oxide have low melting point because they form a small discreet units and have weak attraction to each other because they are not purely ion, carbon dioxide forms a discreet molecule joined together by weak forces but silicon dioxide has three dimension net work and stable because it has no weak forces. Carbon dioxide and oxides of lead exist in gaseous form but oxide of silicon exists in solid form. Under physical properties, the structures of oxides of silicon form a three dimensi on network normally found in solid form unlike its counter part of carbon dioxide, this is because carbon dioxide forms a linear structure and this is the reason as to why carbon dioxide has low melting and boiling point. Silicon dioxide forms a trigonal planar structure with a lone pair, but has various crystal structures. Silicon monoxide does not exist, while oxide of lead forms a pyramidal structure. Chemical properties: Silicon oxide reacts with strong bases showing the acidic character of this oxide. Other oxides of carbon and lead will give acid; lead oxide is a powerful oxidizing agent. Lead oxide reacts with both acids and bases giving lead oxide amphoteric characterHybridization: Silicon dioxide since it exists as a solid with a three dimension figure that has a trigonal planar structure, its hybridization is SP3.note that there is no pi-pi bond in silicon dioxide, that is hybridization. Carbon dioxide has a linear structure and its hybridization is SP, oxides of lead ex ists in different structures but mostly pyramidal with several lone pairs depending with the oxide, its hybridization can be SP3 or dSP2.

How Does Priestley Present Gerald As An Upper Class Man...

How does Priestley present Gerald as an upper-class man? An Inspector Calls is a play written in 1945 by J.B Priestly. It was set in 1912 where there were strong distinctions between the upper and lower classes. Therefore, to convey the socialist message, Priestly portrays characters from the upper class in an exposed manner. He definitely doesn’t hide any of their flaws. Gerald Croft is one of the main characters in the play that Priestly has done a great job at showing the thoughts of the upper class. Gerald Croft is an aristocrat; the son of ‘Lady Croft’. Aristocracy was social class considered the highest of that society. Therefore, he is above the Birlings socially. At the beginning of Act 1, Mr Birling told Gerald that his mum, ‘while she doesn’t object to my girl, feels you might have done better socially’. Mr Birling knows that his parents were not particularly impressed by the engagement ,which may be why they declined the invitation to the dinner, and he tries to impress him by saying how he might get a knighthood. Mr Birling sees Gerald as an asset for not only his company (as Gerald works at his father s company, Crofts Limited, which is both bigger and older than Mr Birling’s company) but an opportunity for him to climb higher in the social system. This attitude contrasts to Gerald’s attitude a bit because he was prepared to marry Sheila, despite her lower social position.

The Effect of Extreme Dependency on Computers| Extreme Dependency on Technology Technology, good or bad? Some say it’s great, but that is said by drug users about illegal substances as well. They are essentially one in the same; once you have used them and they become part of your life, you are never the same again. Once you have researched via computer, or found your way to an unfamiliar area with a gps, doing it the old way is never as easy or as foolproof as it once was. We will write a custom essay sample on Qwerty or any similar topic only for you Order Now These days, when you loose your phone or even have little reception, you worry; your pulse races, your palms sweat, and you perspire. This is not good. Something that used to make our lives easier now makes our lives harder. Most of us don’t even know how to use a map or to mail a letter anymore. The library, what’s that? If you go to a library, it’s probably to use the internet, not to read a book. The computer is a wonderful invention if you like moving fast. We can do everything a computer can, except it takes us much longer. Wall Street is a big blue and green blur of humming computers and screens, it almost seems to have a life of its own, it’s like an urban jungle. If that system crashes, our economy falls to the ground in flames as well. Books are written in months instead of years. School becomes a mad thrash to get everything typed, created, or turned in on time. What happened to good old paper and calculators? Calculators are a hot issue in my opinion. While they are wonderful little contraptions, our dependency on calculators is worrying. When I walk through that door into the calc room, my grade rests in the hands of a small shiny piece of blue plastic dotted with smooth yellow buttons and stuffed with four triple-A batteries. Compare me to a crack addict, honestly; without my Texas instruments calculator I’m as good as dead. Gps’s are amazing little gadgets. About the size of a slice of bread, they help you find your way like a personal tour guide perched on your dashboard. Maps might as well be carved in stone; they’re old news. Does a map tell you where the nearest taco bell is? Does it recalculate when you miss a turn? Unfortunately, no — Gps’s are a godsend for the directionally challenged. The subtle, warm feeling of accomplishment you get when you find your way around with a crumpled up paper map is likely gone for good, it’s a shame. Survival of the fittest, I guess. But when you run out of batteries, or your gps breaks; good luck finding your way. They are as addicting as anything else humankind has created. As I was browsing for a topic for my illustrative essay, something funny happened. I clicked my merry little way to Google. And within minutes, I had a topic, quite ironically, about dependency on computers. My initial thought on what to write about did not come about by careful thought and planning, it came about through Google and my horrid dependency on computers. Dependency on computers is unavoidable, unless you are Amish or a member of a tribe deep within the jungle. Computers have allowed us the monumental achievement of space travel, the wonder of deep sea submersibles, and the deadliness of heat seeking missiles. No doubt, great achievements not possible without computers. But for everyday activities like finding your way, doing mental math, or writing a paper, computers are a shortcut, they make life easier. We need to learn to do things with and without a computer. For example, I know many people who cannot do mental math to save their lives. At this point, technology is really part of us. Instead of having that knowledge of simple math to rely on, we build upon the base that calculators provide instead. More advanced math is not possible without that technology, though honestly we should be able to do it either way. Through this it’s much easier to screw things up; once you have become used to listening to music anywhere, anytime, through your ipod, it’s a downer to not have music. If your ipod breaks, it’s almost like quitting smoking. You MUST buy a new one, you can’t just stop listening. Cell phones are an utmost convenience. Nary a child or senior citizen lacks one, and they do everything from email to texting to taking pictures. How long until they come equipped with electric toothbrushes? If you’ve ever been in an accident or had car trouble, that cell phone is your lifeline, and there is no alternative. You cannot mail someone; and pay phones are nearly nonexistent. Without your phone, you get the jitters, you feel unsafe, and out of it. It happens to me on those days where I forget and leave it at home – I know 95% of the population is the same way. So obviously technology had done much good. Our quality of living has gone up substantially. But at the same time being perched up her in this greatly advanced society, on top of stacks of microchips and USB ports, it’s a lot easier to lose our footing and tumble back to earth. At some point, the infrastructure will crumble; everything needs an overhaul sooner or later. We would live in much more stable times if it were not for computers. On the same note, we would live in a much slower, less equipped world. Is his a good trade off? It depends on your outlook and opinion. There is no doubt technology can crash and burn, and there is no doubt that technology has simplified out lives. Hopefully we can stabilize it before something drastic happens and we are left moving at 1889 speed. Thus technology has made it a whole lot easier to do most things – and much easier to mess them up – a double-edged sword| Computer addiction  is a mental illness which causes the ex cessive use of  computers  to the extent that it interferes with daily life.

Physical cosmology Universe  · Big Bang Age of the universe Timeline of the Big Bang Ultimate fate of the universe [show]Early universe [show]Expanding universe [show]Structure Formation [show]Components [show]Timeline [show]Experiments [show]Scientists v †¢ d †¢ e The multiverse (or meta-universe, metaverse) is the hypothetical set of multiple possible universes (including the historical universe we consistently experience) that together comprise everything that exists: the entirety of space, time, matter, and energy as well as the physical laws and constants that describe them. The term was coined in 1895 by the American philosopher and psychologist William James. [1] The various universes within the multiverse are sometimes called parallel universes. The structure of the multiverse, the nature of each universe within it and the relationship between the various constituent universes, depend on the specific multiverse hypothesis considered. Multiverses have been hypothesized in cosmology, physics, astronomy, religion, philosophy, transpersonal psychology and fiction, particularly in science fiction and fantasy. In these contexts, parallel universes are also called alternative universes, quantum universes, interpenetrating dimensions, parallel dimensions, parallel worlds, alternative realities, and alternative timelines, among others.

The levels according to Tegmarks classification are arranged such that subsequent levels can be understood to encompass and expand upon previous levels, and they are briefly described below. [2][3] [edit]Level I: Beyond our cosmological horizon A generic prediction of chaotic inflation is an infinite ergodic universe, which, being infinite, must contain Hubble volumes realizing all initial conditions. Accordingly, an infinite universe will contain an infinite number of Hubble volumes, all having the same physical laws and physical constants. In regard to configurations such as the distribution of matter, almost all will differ from our Hubble volume. However, because there are infinitely many, far beyond the cosmological horizon, there will eventually be Hubble volumes with similar, and even identical, configurations. Tegmark estimates that an identical volume to ours should be about 1010115 meters away from us (a number larger than a googolplex). [4][5] [edit]Level II: Universes with different physical constants Bubble universes, every disk is a bubble universe (Universe 1 to Universe 6 are different bubbles, they have physical constants that are different from our universe), our universe is just one of the bubbles. In the chaotic inflation theory, a variant of the cosmic inflation theory, the multiverse as a whole is stretching and will continue doing so forever, but some regions of space stop stretching and form distinct bubbles, like gas pockets in a loaf of rising bread. Such bubbles are embryonic level I multiverse s. Linde and Vanchurin calculated the number of these universes to be on the scale of 1010107. [6] Different bubbles may experience different spontaneous symmetry breaking resulting in different properties such as different physical constants. [4] This level also includes John Archibald Wheelers oscillatory universe theory and Lee Smolins fecund universes theory. [edit]Level III: Many-worlds interpretation of quantum mechanics Hugh Everetts many-worlds interpretation (MWI) is one of several mainstream interpretations of quantum mechanics. In brief, one aspect of quantum echanics is that certain observations cannot be predicted absolutely. Instead, there is a range of possible observations each with a different probability. According to the MWI, each of these possible observations corresponds to a different universe. Suppose a die is thrown that contains 6 sides and that the result corresponds to a quantum mechanics observable. All 6 possible ways the die can fall correspond to 6 different universes. (More correctly, in MWI there is only a single universe but after the split into many worlds these cannot in general interact. [7] Tegmark argues that a level III multiverse does not contain more possibilities in the Hubble volume than a level I-II multiverse. In effect, all the different worlds created by splits in a level III multiverse with the same physical constants can be found in some Hubble volume in a level I multiverse. Tegmark writes that The only difference between Level I and Level III is where your doppelgangers reside. In Level I they live elsewhere in good old three-dimensional space. In Level III they live on another quantum branch in infinite-dimensional Hilbert space. Similarly, all level II bubble universes with different physical constants can in effect be found as worlds created by splits at the moment of spontaneous symmetry breaking in a level III multiverse. [4] Related to the many-worl ds idea are Richard Feynmans multiple histories interpretation and H. Dieter Zehs many-minds interpretation. [edit]Level IV: Ultimate Ensemble The Ultimate Ensemble hypothesis of Tegmark himself. This level considers equally real all universes that can be defined by mathematical structures. This also includes those having physical laws different from our observable universe. Tegmark writes that abstract mathematics is so general that any Theory Of Everything (TOE) that is definable in purely formal terms (independent of vague human terminology) is also a mathematical structure. For instance, a TOE involving a set of different types of entities (denoted by words, say) and relations between them (denoted by additional words) is nothing but what mathematicians call a set-theoretical model, and one can generally find a formal system that it is a model of. He argues this implies that any conceivable parallel universe theory can be described at Level IV and subsumes all other ensembles, therefore brings losure to the hierarchy of multiverses, and there cannot be say a Level V. [8] Jurgen Schmidhuber, however, says the set of mathematical structures is not even well-defined, and admits only universe representations describable by constructive mathematics, that is, computer programs. He explicitly includes universe representations describable by non-halting pro grams whose output bits converge after finite time, although the convergence time itself may not be predictable by a halting program, due to Kurt Godels limitations. 9][10][11] He also explicitly discusses the more restricted ensemble of quickly computable universes. Cyclic theories Main articles: Cyclic model and Oscillatory universe In several theories there is a series of infinite, self-sustaining cycles (for example: an eternity of Big Bang-Big crunches). [edit]M-theory See also: Brane cosmology and String theory landscape A multiverse of a somewhat different kind has been envisaged within the multi-dimensional extension of string theory known as M-theory, also known as Membrane Theory. 13] In M-theory our universe and others are created by collisions between p-branes in a space with 11 and 26 dimensions (the number of dimensions depends on the chirality of the observer);[14][15] each universe takes the form of a D-brane. [14][15] Objects in each universe are essentially confined to the D-brane of their universe, but may be able to interact with other universes via gravity, a force which is not restricted to D-branes. [16] This is unlike the universes in the quantum multiverse, but both concepts can operate at the same time. [edit]Anthropic p rinciple Main article: Anthropic principle The concept of other universes has been proposed to explain why our universe seems to be fine-tuned for conscious life as we experience it. If there were a large number (possibly infinite) of different physical laws (or fundamental constants) in as many universes, some of these would have laws that were suitable for stars, planets and life to exist. The weak anthropic principle could then be applied to conclude that we would only consciously exist in those universes which were finely-tuned for our conscious existence. Thus, while the probability might be extremely small that there is life in most of the universes, this scarcity of life-supporting universes does not imply intelligent design as the only explanation of our existence. [edit]WMAP cold spot Laura Mersini-Houghton claims that the WMAP cold spot may provide testable empirical evidence for a parallel universe within the multiverse. [edit]Criticisms [edit]Non-scientific claims Critics claim that many of these theories lack empirical testability, and without hard physical evidence are unfalsifiable; outside the methodology of scientific investigation to confirm or disprove. Reasons why such claims lack empirical evidence or testability according to most Multiverse theories is that other universes are in a different spacetime framework, so in principle they cannot be observed. [edit]Indirect Evidence The logical foundation of modern science is hypothetico-deductive logic which permits a theory to propose unobvservable entities if these help explain observable outcomes, either by theory based predictions (of future observations) or retroductionism (of already known observations). [17] [edit]Occams Razor See also: Kolmogorov complexity Critics argue that to postulate a practically infinite number of unobservable universes just to explain our own seems contrary to Occams razor. [18][19] Tegmark answers: A skeptic worries about all the information necessary to specify all those unseen worlds. But an entire ensemble is often much simpler than one of its members. This principle can be stated more formally using the notion of algorithmic information content. The algorithmic information content in a number is, roughly speaking, the length of the shortest computer program that will produce that number as output. For example, consider the set of all integers. Which is simpler, the whole set or just one number? Naively, you might think that a single number is simpler, but the entire set can be generated by quite a trivial computer program, whereas a single number can be hugely long. Therefore, the whole set is actually simpler. Similarly, the set of all solutions to Einsteins field equations is simpler than a specific solution. The former is described by a few equations, whereas the latter requires the specification of vast amounts of initial data on some hypersurface. The lesson is that complexity increases when we restrict our attention to one particular element in an ensemble, thereby losing the symmetry and simplicity that were inherent in the totality of all the elements taken together. In this sense, the higher-level multiverses are simpler. Going from our universe to the Level I multiverse eliminates the need to specify initial conditions, upgrading to Level II eliminates the need to specify physical constants, and the Level IV multiverse eliminates the need to specify anything at all. He continues A common feature of all four multiverse levels is that the simplest and arguably most elegant theory involves parallel universes by default. To deny the existence of those universes, one needs to complicate the theory by adding experimentally unsupported processes and ad hoc postulates: finite space, wave function collapse and ontological asymmetry. Our judgment therefore comes down to which we find more wasteful and inelegant: many worlds or man y words. Perhaps we will gradually get used to the weird ways of our cosmos and find its strangeness to be part of its charm. Multiverse hypotheses in philosophy and logic edit]Modal realism Possible worlds are a way of explaining probability, hypothetical statements and the like, and some philosophers such as David Lewis believe that all possible worlds exist, and are just as real as the actual world (a position known as modal realism). [20] [edit]Trans-world identity A metaphysical issue that crops up in multiverse schema that posit infinite identical copies of any given universe is that of the notion that there can be identical objects in different possible worlds. According to the counterpart theory of David Lewis, the objects should be regarded as similar rather than identical. 21][22] [edit]Fictional realism The view that because fictions exist, fictional characters exist as well. There are fictional entities, in the same sense as that in which, setting aside philosophical disputes, there are people, Mondays, numbers and planets. [23][24] [edit]Multiverse hypotheses in religion and spirituality Main a rticle: Multiverse (religion) [edit]Hinduism Main article: Hindu cosmology The concept of multiple universes is mentioned many times in Hindu Puranic literature, such as in the Bhagavata Purana: Because You are unlimited, neither the lords of heaven nor even You Yourself can ever reach the end of Your glories. The countless universes, each enveloped in its shell, are compelled by the wheel of time to wander within You, like particles of dust blowing about in the sky. The srutis, following their method of eliminating everything separate from the Supreme, become successful by revealing You as their final conclusion (Bhagavata Purana 10. 87. 41) [edit]Islam Main article: Islamic cosmology There are exactly seven verses in the Quran that specify that there are seven heavens. One verse says that each heaven or sky has its own order, possibly meaning laws of nature. Another verse says after mentioning the seven heavens and similar earths. So [Allah] decreed them as seven heavens (one above the other) in two days and revealed to each heaven its orders. And We [Allah] adorned the lowest heaven with lights, and protection. Such is the decree of the Exalted; the Knowledgeable. [Quran 41. 12] Fakhr al-Din al-Razi (1149–1209), in dealing with his conception of physics and the physical world in his Matalib, explores the notion of the existence of a multiverse in the context of his commentary on the Quranic verse, All praise belongs to God, Lord of the Worlds. He raises the question of whether the term worlds in this verse refers to multiple worlds within this single universe or cosmos, or to many other universes or a multiverse beyond this known universe. Al-Razi disagreed with the Aristotelian and Avicennian view of the impossibility of multiple universes. This disagreement arose from his affirmation of atomism, as advocated by the Ashari scho ol of Islamic theology, which entails the existence of vacant space in which the atoms move, combine and separate. 25] He argued that God has the power to fill the vacuum with an infinite number of universes. [26] [edit]Planes of existence Main article: Plane (esotericism) Certain religions and esoteric cosmologies propound the idea of a whole series of subtle emanated planes or worlds. [edit]Afterlife Many religions include an afterlife existence in realms, such as heavens and hells, which may be very different from the observable universe. [edit]Eschatology See also: End time Eschatological scenarios may include a new different world after the end time of the current one. For example, Hindu cosmology includes the idea of an infinite cycle of births and deaths and an infinite number of universes with each cycle lasting 8. 4 billion years. [27] Similar eschatological scenarios appear in other religions, in the form of belief in there being a new and different world after the end time of the current one.

Please reorganize this content to explain the subjects impact on popular culture rather than simply listing appearances, and remove trivial references. May 2010) See also: Parallel universe (fiction) and Fictional universe [edit]Literature The term Multiverse was notably used in 1962 by science fiction author Michael Moorcock, though not for the first time in literature, having previously been used by both William James in 1895 and John Cowper Powys in his 1955 novel The Brazen Head (p. 279). The author and editor Paul le Page Barnett, best known by the pseu donym John Grant, later used the term polycosmos for a similar concept binding together a number of his works. He formed the word from Greek morphemes where multiverse uses Latin. [28] Philip K. Dicks The Man in the High Castle Takes place in a parallel universe where the allies lost WWII. The novel follows several characters, one of whom travels to what is implied as an alternate universe for a short time. (our own) In the World of Tiers novels (1965) by Philip Jose Farmer, the background of the stories are set in a multiverse where godlike beings are able to create a number of pocket universes at their whim. Our own universe is part of this series, but interestingly its boundary appears to end at the edge of the solar system. In a 1971 short story All the Myriad Ways, author Larry Niven explores the psychological implications of Multiverse theory. The story somewhat erroneously postulates that since a split in the Multiverse is created at each decision point, the number of suicides would rise dramatically as people consider how the possibility of ending their lives would impact the many versions of the universe. The idea is that simply considering the act causes all possible outcomes to occur in somewhat equal proportion. While the story is highly entertaining, this notion is pure fiction, and is not supported by any significant theory of muitiple universes. The way in which Robert A. Heinlein used interlocking characters and settings in his novels have led to his worlds being described as a multiverse. [29] In C. S. Lewiss series The Chronicles of Narnia, multiple universes exist within a monotheistic, rather than a naturalistic framework. At the will of Aslan (who corresponds to the Christian God), the main characters enter different universes through various means, including a forest containing pools of water. A leap into any pool will take one into a universe with natural laws and even a structure differing from our own. (In Narnia, for instance, the world is not spherical, but flat, and the brave mouse Reepicheep travels to the end of it in order to enter Aslans Country. In Philip Pullmans trilogy His Dark Materials the lead characters enter parallel universes by using a knife to cut into the fabric of reality. The novel Timeline by Michael Crichton uses the multiverse theory as a mechanism for travel back to medieval times to research the Hundred Years War. A 2000 Dean Koontz Novel, From the Corner of His Eye, is based entirely around the belief in multiple realities. At least four characters in the book have special abilities based around the use of multiple realities. Stephen Kings Dark Tower series presupposes the idea of a multiverse, an infinity of infinities, all meeting at a central nexus point in space and time, the Dark Tower itself. The Hitchhikers Guide to the Galaxy features the Whole Sort of General Mish-Mash, in which every possible universe is located at some point along the probability axis. The 2004 Andrew Crumey novel Mobius Dick uses Everetts Many Worlds theory as support for a plot involving both multiple histories (Britain as Fascist or Communist state) and multiple literatures (alternative versions of works by Thomas Mann). Crumey has done academic research on Walter Benjamin and the multiverse of Louis Auguste Blanqui. In the fictional series of Robert Jordans World of the Wheel of time, the main character Rand Al Thor at one time uses his One power to channel power through a Portal stone which causes him and his troupe to experience lives in various probability universes, which however always end with his death (he is a pivotal character in the series on account of the dark one). Both DC Comics and Marvel Comics have made extensive use of the multiverse concept, with DC adopting the notion (later adapted by Marvel) of numbering the many different versions of Earth presented, which culminated in the Crisis on Infinite Earths story arc of the 1980s, and its later sequels Infinite Crisis, 52 and Final Crisis. An example of Marvel using the multiverse concept is the Marvel Zombies series and the Ultimate line of comics which take place in an alternate universe. In the manga Katekyo Hitman Reborn! , the main antagonist of the future arc, Byakuran, is capable of moving between parallel universes, and he also manages to bring himself from one universe to another. [edit]Film In the 2001 Jet Li film, The One, Jet Lis character travels to several different universes to carry out his deadly deeds. Although not explicitly described as such in the film, the alternate reality experienced by the George Bailey and Clarence characters in the 1946 film Its a Wonderful Life may be interpreted as a parallel universe. The 2009 film Star Trek features the characters of Spock and Nero traveling backwards in time by means of a black hole, drastically altering the timeline. Though this is not a true alternate universe, it presents an altered history within our original universe. [edit]Television In the 2010 season of Lost a new flash sideways storyline seemed to show a parallel universe where the passengers of Oceanic Flight 815 land safely in Los Angeles and the island they originally crashed on is now underwater. The idea that it was a parallel universe arose from events in the previous season involving several main characters on the island that had traveled back in time to the year 1977. In the episodes leading up to the end of the 2009 season it was implied that detonating a hydrogen bomb within a pocket of electromagnetic energy could reset time and make it so Oceanic Flight 815 never crashed, which leads to the characters who are stuck in 1977 detonating the bomb in the final moments of the season finale. When the 2010 season opened with what appeared to be two different timelines, one where the plane never crashed and one where the characters that detonated the bomb are back to their original time yet still stuck on the island, it seemed to imply to the viewers that the bomb had created a parallel universe instead of just resetting the one they were in like they had thought it would. However, in the 2010 series finale, it is revealed that the bomb did not reset time or create a parallel universe. Instead the flash sideways world is actually a super flash forward set after all the events on the island that shows a spiritual gateway to the afterlife, created by the characters to find one another after they die and to allow themselves to let go of their physical lives before moving on, rather than an actual parallel universe in the physical sense. During the Android Arc in Dragon Ball Z, the shows main character, Son Goku dies from an incurable heart virus roughly two and a half years after killing Frieza and his father King Cold. Six months later, a pair of androids appear and kill all of the Z fighters (except for Son Gohan and infant Trunks). As a result of this divergent timeline, several key characters are not born. These characters are: Goten, Pan, Bra, Marron and Uub. Trunks, now nearly an adult, travels 20 years into the past where/when the main timeline viewers are familiar with exists. In the network movie Turtles Forever, the 2003 turtles meet their 1980s conterparts, claiming that they came from an alternate universe. It is later revealed that there is a multiverse of the Teenage Mutant Ninja Turtles. The television show Sliders was based entirely on the possibility of parallel universes. In each episode the stars experienced an alternate universe through the use of a device that would create a portal through which to travel to those alternate realities. In the season 8 premiere of Family Guy, Stewie and Brian use an enhanced device to travel to different universes. They temporarily stay in a world that has not been influenced by Christianity, therefore the world being technologically head 1000 years, and a world where dogs are the dominant species before returning to their world. The Fox show Fringe explores an alternate universe as part of its series-wide plot. The show also touches on crossing over to the other side, the advancement of science and technology bringing two worlds together, as well as the possibility of two worlds colliding and bringing one of them to an end. Several storylines in the Star Trek and Doctor Who franchises have involved multiverses. Examples include: Mirror, Mirror (and sequels) in Star Trek: The Original Series; Parallels in Star Trek: The Next Generation; and Inferno, Rise of the Cybermen and Turn Left in Doctor Who. Stargate SG-1, Stargate Atlantis, and Stargate Universe also have episodes where people travel to different parallel universes and alternate timelines. Episodes include There but for the Grace of God, 2010, 2001, Moebius parts 1 and 2, Before I Sleep, Mackay and Mrs. Miller, The Last Man, Vegas and Time.
