Guided routes · the same site, by how much time you have

How much processing power a simulated world takes, and when our computers could run it.

1. The Sandbox · The baseline world, Earth atom by atom since 1900, and the computing it takes: 10⁶⁸ operations a second.
2. What a computer can run · The same sum run backwards: what every computer on Earth, or a star, could run instead.
3. The countdown · When our computers could run each scenario if processing power keeps growing, and which ones never get there.
4. Tests · Has anyone looked for the seams, and what did they find?

The argument, the model behind the numbers, and the case against it.

1. Bostrom’s trilemma · The argument in three propositions, and why at least one must be true.
2. Thinkers · The same question from Plato’s cave to Chalmers, each one tied to a dial.
3. Your Reality · Ten questions that build a world and measure it as you answer.
4. Method · One formula, every constant with its source, and how far you can trust each one.
5. Simulations within simulations · Why every stack of simulations has to end.
6. Objections · Nine objections, and where a computing model stops.
7. Reading · Where to go next, with a difficulty tag on each.

Everything you need to check, reuse or extend the model.

1. Method · The formula, the physical anchors, the ladders and the dated changelog.
2. The Sandbox · Every total with its 80% range, and the inputs ranked by influence. You can compare worlds and copy a citation.
3. Engine API · The engine as JSON. /api/price takes the parameters from any Sandbox link. /api/budget runs it backwards.
4. Datasets · The site’s datasets as open JSON, with a catalogue. Entities publishes its own under /entities.
5. Tests · Experiments and bounds, with checked citations.
6. Entities · Minds and collectives, sourced and tagged.
7. Licence · CC BY 4.0: what you can reuse, and the credit line.
