How this entity was disambiguated
This entity first appeared as the object of triple T9600411 — 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.

Schwarzschild method in galactic dynamics
The Schwarzschild method in galactic dynamics is a numerical orbit-superposition technique used to construct self-consistent models of galaxies and infer their mass distributions, including dark matter and central black holes.
-
D.
Brans–Dicke theory
Brans–Dicke theory is an alternative theory of gravitation to Einstein’s general relativity that introduces a scalar field to allow for a varying gravitational “constant.”

E.
Milky Way dark matter halo
The Milky Way dark matter halo is the vast, roughly spherical, invisible mass of dark matter surrounding our galaxy that dominates its gravitational potential and governs the motions of its stars, gas, and satellite galaxies.
- 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: Modified Newtonian Dynamics Description of subject: Modified Newtonian Dynamics is an alternative theory of gravity proposed to explain galaxy rotation curves and other astrophysical phenomena without invoking dark matter.
