Lambda-CDM model

E121003

cosmological model standard model of cosmology

The Lambda-CDM model is the standard cosmological framework describing a universe dominated by dark energy (Λ) and cold dark matter (CDM), successfully explaining the large-scale structure, expansion history, and cosmic microwave background observations.

How these facts were elicited

The pipeline generated the facts above by prompting gpt-5.1 with this entity's name + description and the instruction below.

Instruction

You are a knowledge base construction expert. Given a subject entity and a description of it, return factual statements that you know for the subject as a JSON list of dictionaries(triples), where keys must be "subject", "predicate" and "object". The number of facts may be very high, between 25 to 50 or more, for very popular subjects. For less popular subjects, the number of facts can be very low, like 5 or 10.

# Requirements
- If you don't know the subject at all, return an empty list.
- If the subject is not a named entity, return an empty list.
- Include at least one triple where predicate is "instanceOf".
- Do not get too wordy.
- Separate several objects into multiple triples with one object.

Input

Subject: Lambda-CDM model
Description of subject: The Lambda-CDM model is the standard cosmological framework describing a universe dominated by dark energy (Λ) and cold dark matter (CDM), successfully explaining the large-scale structure, expansion history, and cosmic microwave background observations.
