Black holeEvent horizon

Permalink to relation

This is an authored directed relation from the source endpoint to the target endpoint.

Authored explanation

In standard asymptotically predictable settings, the event horizon is the boundary of the black-hole region.

How to interpret this relation type

The target represents a state, property, observable, or state-dependent description associated with the source system or theory.

Causal structureEvent horizon

Permalink to relation

This is an authored directed relation from the source endpoint to the target endpoint.

Authored explanation

An event horizon is defined globally from causal reachability relative to an exterior future; it is not determined from local curvature data alone.

How to interpret this relation type

The target represents a state, property, observable, or state-dependent description associated with the source system or theory.
