Editorial method
The Spacetime Metric explains physics through experiments, mathematical models, and the papers behind them. These are the rules for preparing and reviewing its lessons.
Start with the original work
Check the paper or other original record, including corrections and later measurements. A summary must be supported by that source, not inferred from its title. Credit the creators in the published order and give readers a usable original link.
State the result precisely
A calculation describes a model under stated assumptions. An experiment measures something with an apparatus and an uncertainty. Neither becomes a working technology simply by being discussed. Explain those distinctions in the lesson itself, including null results and disagreements that change its meaning.
Repetition is not independent confirmation. Follow repeated reports back to their source, and distinguish them from a separate experiment or analysis.
Make the explanation usable
Pair equations with plain-language explanations. Describe what a diagram represents, and distinguish an analogy from the physical system. Younger readers need a concrete observation or safe activity and a short question to check their understanding. Translations need scientific and language review as well as matching page structure.
Keep review and corrections traceable
Internal review records retain source locations, revision dates, and checks on factual claims. Writing and narration tools may assist production; their use does not establish a claim’s accuracy. Publication requires source checks and editorial review. Report an error through the contact page, naming the page, passage, and supporting source when available.
Respect each item’s rights
The site license does not relicense third-party papers, images, recordings, or other works. Their own rights and access terms govern whether we may reproduce, embed, or link to them. An accessible original is not, by itself, permission to copy it.
