When making a
timeline for a fictional universe, there are many
Speculative Fiction Tropes that tend to pop up, especially if it is based on the real world. This list notes them in the order they (typically) appear. Its purpose is both to help with
World Building, and to help when writing a
crossover.
This list also includes nonfictional historical and scientific "facts" that are the basis of many fictional stories, such as the "
A meteor killed off the dinosaurs" theory.
Related to
Hollywood History, but more detailed.
Examples:
- Billions of Years Ago:
- Creation Of The Universe — Either the Big Bang or some Supreme Being (or both, they aren't mutually exclusive) creates the universe (or recreates it, see End of The Universe below) approx. 13.5 Billion years ago (according to the latest theories.)
- Precursors begin to appear.
- The Earth forms. (Scientific theory — Approx. 5 Billion Years ago.)
- Life begins on Earth. (Theory — Approx. 3 Billion years ago.)
- Might possibly have been influenced by the Precursors.
- Millions of Years Ago:
- One Million BC:
- The Time of Myths:
- Humanity spreads over Earth and develops several cultures.
- Beings of great power are worshiped as gods. Some may actually be aliens in disguise. Example: Stargate.
- Some humans are taken off planet and end up colonizing other worlds, then forgetting about Earth. (This explains all those Human Aliens.) Ex: Again, Stargate.
- The Dark Ages:
- The Present:
- The Near Future:
- Before FTL is invented:
- The solar system is colonized.
- But the colonies may fight for independence. Ex. Gundam
- After FTL is invented:
- Very Far Into the Future: (let's say, for the purposes of symmetry, A.D. One Million)
- The End of the Universe:
