How this entity was disambiguated
This entity first appeared as the object of triple T692583 — 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: eternal inflation Context triple: [Alan Guth, notableIdea, eternal inflation]
-
A.
de Sitter spacetime
de Sitter spacetime is a maximally symmetric, curved solution of general relativity that models an expanding universe dominated by a positive cosmological constant (dark energy).

B.
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.
-
C.
The Restless Universe
The Restless Universe is a popular science book by physicist Max Born that explains modern physics and quantum theory to a general audience in clear, accessible language.

D.
Black Holes and Baby Universes and Other Essays
Black Holes and Baby Universes and Other Essays is a 1993 collection of popular-science essays and reflections by physicist Stephen Hawking, exploring cosmology, black holes, and his personal life and ideas.
-
E.
The Grand Design
The Grand Design is a popular-science book co-authored by Stephen Hawking and Leonard Mlodinow that explores modern cosmology, quantum theory, and the origins of the universe while arguing that physics can explain creation without invoking a deity.

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: eternal inflation Description of subject: Eternal inflation is a cosmological theory proposing that the rapid expansion of space continues indefinitely in some regions, constantly spawning new "bubble" universes with potentially different physical properties.
