A megastructure is a very large artificial object, although the limits of precisely how large vary considerably. Some apply the term to any especially large or tall building. Some sources define a megastructure as an enormous self-supporting artificial construct. The products of megascale engineering or astroengineering are megastructures. The lower bound of megastructural engineering might be considered any structure that has any single dimension 1 megameter (1000 km) in length.

Dark matter is defined as hypothetical matter that is undetectable by its emitted radiation, but whose presence can be inferred from gravitational effects on visible matter. It has been used in a variety of fictional media, including computer and video games and books. In such cases, dark matter is usually attributed extraordinary physical or magical properties. Such descriptions are often inconsistent with the known properties of dark matter proposed in physics and cosmology. For example, in computer games, it is often used as material for making weapons and items, and is usually depicted as black or a similar color.

The cover art for the books in the series is created by Stephen Hickman.
In speculative fiction, floating cities and islands are a common trope, which range from cities and islands that float on water to ones that float in the atmosphere of a planet by purported scientific technologies or by magical means. While very large floating structures have been constructed or proposed in real life, aerial cities and islands remain in the realm of fiction.

The space-opera blockbuster, Star Wars franchise has borrowed many real-life scientific and technological concepts in its settings. In turn, Star Wars has depicted, inspired, and influenced several futuristic technologies, some of which are in existence and others under development. In the introduction of the Return of the Jedi novelization, George Lucas wrote: "Star Wars is also very much concerned with the tension between humanity and technology, an issue which, for me, dates back even to my first films. In Jedi, the theme remains the same, as the simplest of natural forces brought down the seemingly invincible weapons of the evil Empire."
Space travel, or space flight is a classic science-fiction theme that has captivated the public and is almost archetypal for science fiction.
