Galactic empires are a science fiction setting trope, in which most or all of the habitable planets in the setting's galaxy are ruled by a single centralized political entity. Galactic empires most frequently appear in works in the sub-genres of science fantasy and space opera, although they may appear in other sub-genres as well. Works featuring galactic empires may have them as the story's focus, chronicling the empire's growth and/or decline. Alternatively, they may merely serve as a backdrop against which the events of the story play out.
A parallel universe, also known as an alternate universe, parallel world, parallel dimension, alternate reality, or alternative dimension, is a hypothetical universe co-existing with one's own, typically distinct in some way. The sum of all potential parallel universes that constitute reality is often called the "multiverse". Another common term for a parallel universe is "another dimension", stemming from the idea that if the 4th dimension is time, the 5th dimension—a direction at a right angle to the fourth—is a direction into any of the alternate spacetime realities.

Multiple organizations of the Dune universe dominate the political, religious, and social arena of the setting of Frank Herbert's Dune series of science fiction novels, and derivative works. Set tens of thousands of years in the future, the saga chronicles a civilization which has banned computers but has also developed advanced technology and mental and physical abilities through physical training, eugenics and the use of the drug melange. Specialized groups of individuals have aligned themselves in organizations focusing on specific abilities, technology and goals. Herbert's concepts of human evolution and technology have been analyzed and deconstructed in at least one book, The Science of Dune (2008). His originating 1965 novel Dune is popularly considered one of the greatest science fiction novels of all time, and is frequently cited as the best-selling science fiction novel in history. Dune and its five sequels by Herbert explore the complex and multilayered interactions of politics, religion, ecology and technology, among other themes.
