Exocosm

Exoplanet and fantasy worldbuilding using scientific thinking

About Exocosm

Exocosm aims to discuss worldbuilding from a scientific point of view in the hope that will be of interest to others. This began with exoplanets and speculative evolution for science-fiction worldbuilding. Due to popular demand it now also covers elements suited for fantasy worldbuilding.

Blog Topics

A range of worldbuilding topics across several categories will be discussed. In keeping with the scientific view point of this blog the categories will be named in an academic fashion but, don’t worry, they are aimed at a wider audience than just scientists.

  • Astrobiology: The study of the origin and evolution of life throughout the universe.
  • Exoplanetology: The study of extrasolar planets and the structure of the host star system.
  • Mythology: Magic and concepts not possible with current scientific knowledge.
  • Procedural Generation: Creating data automatically rather than manually.
  • Technology: Earth technology from the past, present and future.

Exordium

Exordium is the original setting (previously known simply as Exocosm) that describes a realistic prediction of humanity’s expansion into the wider cosmos at slower than light speed. This science-fiction and speculative evolution setting will include the following:

  • Automated interstellar probes investigating alien biospheres and distant celestial bodies.
  • Complete colonisation of the solar system and nearby star systems.
  • Advanced but plausible technology.
  • The divergence of humanity into various lineages.

Paracosm

A paracosm is an imaginary world but in contrast to Exordium in the Paracosm worlds fantasy elements play a greater role. From faster than light travel to flat worlds and outright magic, these worlds show “we’re not in Kansas anymore”.

  • Noosphere: A space-fantasy setting involving wormholes and psychic powers.
  • Omnium: A steampunk setting across multiple planes where magic is technology.
  • Xanadu: A mythic setting that operates under a different set of rules than reality.
