A region of spacetime from which no future-directed causal signal can reach a specified exterior infinity; in asymptotically flat settings its boundary is the event horizon.

This is an authored directed relation from the source endpoint to the target endpoint.
Sufficiently compact collapse can produce a trapped black-hole region.
A physical process transforms the source into, or produces, the target under the conditions stated in the edge detail.

This is an authored directed relation from the source endpoint to the target endpoint.
Two black holes can form an inspiraling binary system.
The source is a material constituent, structural component, or underlying quantum field whose excitation realizes the target physical system or particle. The edge label and detail must distinguish composition from field excitation; neither implies a simple classical sum of parts.

In standard asymptotically predictable settings, the event horizon is the boundary of the black-hole region.
The target represents a state, property, observable, or state-dependent description associated with the source system or theory.

Supply the causal horizon and stationary or adiabatically evolving black-hole geometry.
Feed several structures into a construction junction and impose compatibility between them.
einstein-online-black-holesnasa-black-holesThis is an authored directed relation from the source endpoint to the target endpoint.
The Kerr spacetime is the stationary, axisymmetric, asymptotically flat vacuum model used for an uncharged rotating black hole.
The target is a model, idealization, restricted ansatz, approximation scheme, phenomenological fit, or historical representation used for the source system or theory. It need not have a universal small error parameter and is not thereby a controlled limit or effective theory. The edge label and detail must identify the precise status.

The Schwarzschild black-hole spacetime is the static, spherically symmetric, asymptotically flat vacuum model of an uncharged nonrotating black hole.
The target is a model, idealization, restricted ansatz, approximation scheme, phenomenological fit, or historical representation used for the source system or theory. It need not have a universal small error parameter and is not thereby a controlled limit or effective theory. The edge label and detail must identify the precise status.
