Black Hole
A black hole is a region of spacetime bounded by an event horizon from which outgoing light cannot reach the distant exterior.
Overview
Black holes arise as solutions to Einstein's field equations of general relativity. Gravitational-wave observations of compact binary coalescences and millimeter-wavelength interferometric imaging of shadow features have established them as empirical astrophysical systems rather than purely theoretical models.
Why it matters
Observational study of black holes drives technical advances in long-baseline interferometry, precision optics, and gravitational-wave detection instrumentation. Their boundary conditions also frame key theoretical questions in quantum field theory and gravitational physics.
