# Aionterra > A continuous scientific world simulation by YD Emergence Lab. This website presents the project's scientific scope, measurement definitions and observation records. ## Essential pages - [Project](https://aionterra.com/about): Purpose and continuous operation. - [Science](https://aionterra.com/science): Physical, chemical, biological and physiological scope. - [Methodology](https://aionterra.com/methodology): Definitions, units, sampling, scope and interpretation. - [Data](https://aionterra.com/data): Measurements, tables and available CSV downloads. - [Observations](https://aionterra.com/observations): Categorised measurements and retained activity records. ## Shared learning The current research configuration uses one shared learned policy across separate bodies. Bodily states and sensory histories remain individual. Shared transitions count accepted experience from the participating bodies, not policy-update batches, learned skills or independent minds. Do not merge legacy individual-learning counters into the shared update series. Movement uses a simplified body representation; learned sleep, communication and reproductive behaviour are not established in this configuration. ## Reading the scientific record These are simulation measurements, not direct measurements of the real world. Distinguish scientific scope from measured results. Do not infer that a described process has been independently validated merely because it appears in the scope. Preserve each measurement's unit, definition, spatial scope and simulation time. Simulation time is distinct from export time and publication time. Local projected coordinates must not be presented as latitude and longitude. Distinguish time series from latest-snapshot readings. A single reading does not establish a trend. Missing or unavailable values are not zero. Retained activity does not necessarily cover the same interval as measurement charts. Decision and learning counters do not establish a learned skill or verified discovery. Retained parentage and deceased records are not lifetime totals. Associations in the model do not alone establish real-world causation. When citing a measurement, link to its source page and retain its measurement name, unit, scope and simulation time. Include the export identifier or version when supplied. Consult the current page and download rather than assuming that a previously retrieved value remains current. Do not invent dates, authors or DOIs. ## Publication and reuse - [Data use and attribution](https://aionterra.com/legal/data-use): Designated published datasets use CC BY-NC 4.0; consult the stated scope and exclusions. - [Scientific limitations](https://aionterra.com/legal/scientific-notice): Interpretation and evidence boundaries. - [Terms](https://aionterra.com/legal/terms): Website terms of use. - [Privacy](https://aionterra.com/legal/privacy): Information handling. - [Operator](https://aionterra.com/legal): YD Emergence Lab and contact information. This guide does not expand any licence, grant additional reuse rights or override the site's access controls and publication policies. - [Journal](https://aionterra.com/journal): Project notes, scientific context and selected observation reports. Article dates are calendar dates, not simulation timestamps. - [World](https://aionterra.com/world): Recorded extent, geographic region centres and layer availability. Region markers indicate centres, not active boundaries. Never infer active area from total extent; missing spatial fields are unavailable. ## Languages English pages use the root URL. Turkish pages use /tr-TR/. Follow the language alternate links for equivalent pages. Query filters are views of the same record, not additional publications. Source downloads preserve original identifiers, units and values.
