If a Martian comes to Earth and drops a two kilogram brick off the Hope Creek Generating Station cooling tower, we would expect the Earth to be two kilos more massive when it hits the ground. If the brick is a three kilogram brick upon impact, the Earth will be three kilos more massive after impact. That's what the weak nuclear force does - it makes more brick out of kinetic energy derived from the gravitational potential and we do not need a black hole to see the process as it works for any gravitating body in some minute amount. Do we really need complex bookkeeping for this?
