How this entity was disambiguated
This entity first appeared as the object of triple T2465301 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

Target entity: Physical Cosmology Context triple: [James Peebles, notableWork, Physical Cosmology]
-
A.
Gravitation and Cosmology
Gravitation and Cosmology is a landmark graduate-level textbook by Steven Weinberg that presents a comprehensive, modern treatment of general relativity and its applications to cosmology and astrophysics.
-
B.
Big Bang cosmology
Big Bang cosmology is the prevailing scientific framework that explains the origin, early evolution, and large-scale structure of the universe as emerging from an extremely hot, dense initial state that has been expanding over time.
-
C.
FLRW cosmological models
FLRW cosmological models are a family of solutions to Einstein’s field equations that describe a homogeneous and isotropic expanding or contracting universe, forming the standard framework for modern cosmology.
-
D.
Lambda-CDM model
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.
-
E.
observable universe
The observable universe is the portion of the entire cosmos that we can in principle detect or observe from Earth, limited by the finite speed of light and the age of the universe.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.

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: Physical Cosmology Description of subject: Physical Cosmology is a branch of astrophysics that studies the large-scale structure, origin, evolution, and fate of the universe using the laws of physics.
