Science fiction and fantasy are the most widely covered themes in concept art. Concept art has traditionally been used in film poster design but has expanded to cover many genres used in video games. Science fiction explores possible future worlds and technologies through rational narratives, differing from fantasy through its grounding in scientific possibility even if some imaginative elements break natural laws. Common science fiction elements include settings in the future, space, other worlds, aliens, futuristic technology, altered physics, new social systems, and paranormal abilities.

2. • The two most widely covered themes in
concept art are science fiction and fantasy.

3. • Concept art has always had to cover many
subjects, being the primary medium in film
poster design since the early days
of Hollywood, however, since the recent
rise of concept art used in video game
production concept art has expanded to
cover genres from football to
the Mafia and beyond.

4. • Science fiction is a genre of fiction dealing
with imaginary but more or less plausible (or at
least non-supernatural) content such
as future settings,
futuristic science and technology, space
travel, aliens, and paranormal abilities. Exploring
the consequences of scientific innovations is one
purpose of science fiction, making it a "literature
of ideas".

5. • Science fiction is largely based on
writing rationally about alternative possible
worlds or futures.It is similar to, but differs
from fantasy in that, within the context of
the story, its imaginary elements are largely
possible within scientifically established or
scientifically postulated laws of nature(though
some elements in a story might still be pure
imaginative speculation).

6. • The settings for science fiction are often
contrary to known reality, but most science
fiction relies on a considerable degree
of suspension of disbelief, which is
facilitated in the reader's mind by potential
scientific explanations or solutions to
various fictional elements. Science fiction
elements include:

7. • A time setting in the future, in alternative
timelines, or in a historical past that
contradicts known facts of history or
the archaeological record.

8. • A spatial setting or scenes in outer
space (e.g., spaceflight), on other worlds,
or on subterranean earth.

9. • Characters that
include aliens, mutants, androids,
or humanoid robots.

10. • Technology that is futuristic (e.g., ray
guns, teleportation machines,
humanoid computers).Scientific principles
that are new or that contradict known laws
of nature, for example time

11. • travel, wormholes, or faster-than-
light travel.

12. • New and different political or social
systems (e.g. dystopia, post-scarcity, or
a post-apocalyptic situation where
organized society has collapsed).

13. • Paranormal abilities such as mind
control, telepathy, telekinesis,
and teleportation.
• Other universes or dimensions and travel
between them.
