While many justifications for alternate histories involve a multiverse, the "many world" theory would naturally involve many worlds, in fact a continually exploding array of universes. In quantum theory, new worlds would proliferate with every quantum event, and even if the writer uses human decisions, every decision that could be made differently would result in a different timeline. A writer's fictional multiverse may, in fact, preclude some decisions as humanly impossible, as when, in Night Watch, Terry Pratchett

 depicts a character informing Vimes that while anything that can happen, has happened, nevertheless there is no history whatsoever in which Vimes has ever murdered his wife. When the writer explicitly maintains that all possible decisions are made in all possible ways, one possible conclusion is that the characters were neither brave, nor clever, nor skilled, but simply lucky enough to happen on the universe in which they did not choose the cowardly route, take the stupid action, fumble the crucial activity, etc.; few writers focus on this idea, although it has been explored in stories such as Larry Niven's All the Myriad Ways, where the reality of all possible universes leads to an epidemic of suicide and crime because people conclude their choices have no moral import.

In any case, even if it is true that every possible outcome occurs in some world, it can still be argued that traits such as bravery and intelligence might still affect the relative frequency of worlds in which better or worse outcomes occurred (even if the total number of worlds with each type of outcome is infinite, it is still possible to assign a different measure

When you succeed, all the copies of you who made the same decision succeed too. What you do for the better increases the portion of the multiverse where good things happen." This view is perhaps somewhat too abstract to be explored directly in science fiction stories, but a few writers have tried, such as Greg Egan

Many writers — perhaps the majority — avoid the discussion entirely. In one novel of this type, H. Beam Piper's Lord Kalvan of Otherwhen

Lord Kalvan of Otherwhen is a 1965 science fiction novel by H. Beam Piper and is part of his Paratime series of stories. It recounts the adventures of a Pennsylvania State Police who is accidentally transported to a more backward Parallel universe ....
, a Pennsylvania State Police officer, who knows how to make gunpowder, is transported from our world to an alternate universe where the recipe for gunpowder is a tightly held secret and saves a country that is about to be conquered by its neighbors. The paratime patrol members are warned against going into the timelines immediately surrounding it, where the country will be overrun, but the book never depicts the slaughter of the innocent thus entailed, remaining solely in the timeline where the country is saved.

's Doc Sidhe and Sidhe Devil take place between our world, the "grim world" and an alternate "fair world" where the Sidhe retreated to. Although technology is clearly present in both worlds, and the "fair world" parallels our history, about fifty years out of step, there is functional magic in the fair world. Even with such explanation, the more explicitly the alternate world resembles a normal fantasy world, the more likely the story is to be labeled fantasy, as in Poul Anderson's "House Rule" and "Loser's Night."

In both science fiction and fantasy, whether a given parallel universe is an alternate history may not be clear. The writer might allude to a POD only to explain the existence and make no use of the concept, or may present the universe without explanation to its existence.

Ada or Ardor: A Family Chronicle is a novel by Vladimir Nabokov published in 1969.Ada began to materialize in 1959, when Vladimir Nabokov was flirting with two projects: "The Texture of Time" and "Letters from Terra." In 1965, he began to see a link between the two ideas, finally composing a unified novel from February of 1966 to...
 (1969), a story of incest that takes place within an alternate North America settled in part by Czarist Russia, and that borrows from Dick's idea of "alternate-alternate" history (the world of Nabokov's hero is wracked by rumors of a "counter-earth" that apparently is ours). Some critics believe that the references to a counter-earth suggest that the world portrayed in Ada is a delusion in the mind of the hero (another favorite theme of Dick's novels). Strikingly, the characters in Ada seem to acknowledge their own world as the copy or negative version, calling it "Anti-Terra" while its mythical twin is the real "Terra." Not only history but science has followed a divergent path on Anti-Terra: it boasts all the same technology as our world, but all based on water instead of electricity. When a character in Ada makes a long-distance call, all the toilets in the house flush at once to provide hydraulic power.

Alternate history in the contemporary fantasy genre


Many fantasies and science fantasies are set in a world that has a history somewhat similar to our own world, but with magic added. Since the existence of magic implies different laws of nature it is difficult to imagine a credible point of divergence: The effects of divergence would have existed throughout human history and indeed throughout all evolution of life (unless one posits sudden changes in the laws of nature in medieval or modern times brought about by aliens, a time-space warp, etc.). One example of a universe that is in part historically recognizable but also obeys different physical laws is Poul Anderson's Three Hearts and Three Lions

, founder of The Church of Jesus Christ of Latter-day Saints) takes place in an alternate America, beginning in the early 19th century. Prior to that time, a POD occurred: England, under the control of Oliver Cromwell, had banished "makers", or anyone else demonstrating "knacks" (an ability to perform seemingly supernatural feats) to the North American continent. Thus the early American colonists embraced as perfectly ordinary these gifts, and counted on them as a part of their daily lives. The political divisions of the continent is considerably altered, with two large English colonies bookending a smaller "American" nation, one aligned with England, and the other governed by exiled Cavaliers. Actual historical figures are seen in a much different light: Ben Franklin is revered as the continent’s finest "maker", George Washington was executed at the hands of an English army, and "Tom" Jefferson is the first president of "Apallachee", the result of a compromise between the Continentals and the British.

.

Many works of fantasy posit a world in which known practitioners of magic were able to make it function, and where the consequences of such reality would not, in fact, disturb history to such an extent as to make it plainly alternate history. Many ambiguous alternate/secret histories are set in Renaissance or pre-Renaissance times, and may explicitly include a "retreat" from the world, which would explain the current absence of such phenomena.

The boundaries of alternate history

Often readers encounter stories, which read as though they were alternate history, but which were not written as such. An example would be Robert A. Heinlein's The Man Who Sold the Moon
The Man Who Sold the Moon

The Man Who Sold the Moon is a science fiction novella by Robert A. Heinlein written in 1949 and published in 1950, part of his "Future History" of stories sharing a common background from "Life-Line" to "Da Capo "....
. Written in 1949, it posits that the first moon launch is run by a private organization rather than a government agency in the 1960s. New readers encountering the book may well presume that this is alternate history since it is clearly a counter-factual depiction of the first moon launch, now almost 40 years in the past. However, when written, the first moon launch was 20 years in the future. Thus, The Man Who Sold the Moon is out of date science fiction and not true alternate history. Similar well-known examples would be the novels 2001: A Space Odyssey

The basic difference between alternate history and a future history
Future history

A future history is a postulated history of the future that some science fiction authors construct as a common background for fiction. Sometimes the author publishes a Chronology of events in the history, while other times the reader can reconstruct the order of the stories from information provided therein....
 which becomes a kind of alternate history retrospectively is that the former is composed with the author in possession of facts on the course of actual events to which an alternate is posited, while the latter is written by a person having no knowledge of the future and who tries, to the best of his or her ability, to extrapolate from known tends at the time of writing. For example, H.G. Wells in "The Shape of Things to Come

 (1935). During the early years of World War II, Sackville-West penned the science fantasy Grand Canyon (1942) in which the Germans invade a woefully unprepared United States. One could define such tales as borderline alternate history, since they are usually set in a time that is only shortly after the time of writing and the events described could not have occurred without a branching of history before, if only slightly before, the book was written.
