# Everything on this site · the map

This site works out what it would take to simulate a world. It doesn’t argue that we’re in one. The pages below are grouped by what they do.

## Trees

* [Trees](https://simulation-hypothesis.com/trees) · explorable histories
* [Technology tree](https://simulation-hypothesis.com/trees/technology) · 82 nodes: how virtual worlds became possible
* [Simulations tree](https://simulation-hypothesis.com/trees/simulations) · 107 nodes: what we have learned to simulate
* [Ethics tree](https://simulation-hypothesis.com/trees/ethics) · 91 nodes: where our rules came from, and where they go
* [Becoming synthetic](https://simulation-hypothesis.com/trees/synthetic) · 100 nodes: from biological to synthetic life

## Sandbox and tools

* [Sandbox](https://simulation-hypothesis.com/sandbox) · nine parameters, one total: the computing a simulated universe takes
* [Scenarios](https://simulation-hypothesis.com/builds) · 9 preset universes, each worked out
* [Featured scenario](https://simulation-hypothesis.com/today) · one scenario a day, the same for everyone
* [The countdown](https://simulation-hypothesis.com/countdown) · when could our computers run each simulation
* [What a computer can run](https://simulation-hypothesis.com/budget) · given a computer, what world can it run
* [Simulations within simulations](https://simulation-hypothesis.com/nesting) · how deep can a stack of simulations go
* [The computing in one day](https://simulation-hypothesis.com/bill) · how much computing would one day of a life take
* [Mind assessment](https://simulation-hypothesis.com/score) · check a system against the evidence
* [Interactive models](https://simulation-hypothesis.com/simulations/run) · cellular automata, flocking, epidemics, traffic, ant colonies and more, running in your browser

## Field guides

* [Entities](https://simulation-hypothesis.com/entities) · 44 minds and possible minds, in order of evidence
* [Sentience criteria for animals](https://simulation-hypothesis.com/entities/sentience) · the eight criteria from the 2021 review that led UK law to recognise octopuses and crabs as sentient, and what the review found
* [How directed time is estimated](https://simulation-hypothesis.com/entities/control) · how the Entities charts weigh religions, states, parties and corporations by how much of their members’ waking time they direct. Every practice, survey share and source is listed
* [Consciousness indicators for AI](https://simulation-hypothesis.com/entities/indicators) · the fourteen indicators from Butlin, Long and colleagues (2023), taken from six scientific theories of consciousness
* [Simulations](https://simulation-hypothesis.com/simulations) · 18 domains of the simulations people actually run
* [Simulations by floor](https://simulation-hypothesis.com/simulations/floors) · every simulation sorted by the smallest entity it tracks, from quarks up to pure rules
* [Simulations by method](https://simulation-hypothesis.com/simulations/methods) · the same taxonomy sorted by computational method, from Monte Carlo to agent-based to real-time
* [Simulations by era](https://simulation-hypothesis.com/simulations/eras) · when the first simulation of each kind ran, from orreries and war games to the present
* [Simulations by cost](https://simulation-hypothesis.com/simulations/costs) · how much computing each kind of simulation uses, from no computer at all to the largest machines on Earth

## Reference

* [Library](https://simulation-hypothesis.com/library) · 55 terms, each with a definition and what it does in the model
* [Thinkers](https://simulation-hypothesis.com/thinkers) · 14 thinkers, each with its matching sandbox dial
* [Guided routes](https://simulation-hypothesis.com/guide) · five minutes, an hour, or for research
* [Objections](https://simulation-hypothesis.com/objections) · the standard objections, and where the computing model stops
* [Tests](https://simulation-hypothesis.com/tests) · proposed experiments and physical bounds, and what each one found
* [Reading](https://simulation-hypothesis.com/reading) · annotated further reading, with difficulty tags
* [Method](https://simulation-hypothesis.com/method) · how each total is worked out, with sources
