If there is a background scalar field, then the spherically-symmetric solution is the Janis-Newman-Winicour metric which has no horizons (journals.aps.org/prd/abstract/10.1103/PhysRevD.31.1280). It is not the same as a piece of dust falling into already formed Schwarzschild BH. | |

A black hole is a region of spacetime not casually connected to null infinity, i.e., a place from where not even light can escape. This is a more general and more useful definition. | |
