How this entity was disambiguated

This entity first appeared as the object of triple T79745 — 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: Minkowski space-time
Context triple: [theory of relativity, coreConcept, Minkowski space-time]

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. Lorentz transformation
The Lorentz transformation is a set of equations in special relativity that relate space and time coordinates between two inertial reference frames moving at a constant velocity relative to each other, ensuring the constancy of the speed of light.
C. theory of relativity
The theory of relativity is a fundamental framework in physics, developed by Albert Einstein, that revolutionized our understanding of space, time, gravity, and motion.
D. Einstein field equations
The Einstein field equations are the core mathematical framework of general relativity, relating the curvature of spacetime to the distribution of matter and energy.
E. On the Electrodynamics of Moving Bodies
"On the Electrodynamics of Moving Bodies" is Albert Einstein’s 1905 paper that introduced the special theory of relativity, fundamentally redefining concepts of space, time, and motion in physics.
F. None of above. chosen
G. Unsure - the case is ambiguous/there is not enough information to decide.
