      NASA describes a black hole as an object whose gravity is so strong that, within a certain
      distance, nothing can escape, not even light.

## TL;DR

Black holes are compact objects with gravity strong enough to trap light within their event horizons.

## Core Explanation

This repair removes future black-hole sources and remaps claims to NASA and DOI-backed LIGO/Virgo evidence.
