'''Black holes''' were regions in space created when the remains of a dense [[star]] of normal [[matter]] collapsed far enough to drill a hole through the fabric of [[space]], ([[PROSE]]: {{cs|Sanctuary (novel)}}) creating a [[singularity]]. Their incredible density resulted in a strong [[gravity|gravitational]] pull.
