Please correct me if I am wrong, as I have little more than a highschool knowledge of physics until I start at university this year - virtually no knowledge of the quantum side of things just yet. ^^ My thought is, as spaghetification occurs as you approach the centre (not using singularity for reasons specified below) of a black hole, all matter breaks down until it reaches the level of the Higgs-Boson particle, theorised to give all other particles mass (Correct?). At this point, the mass will simply vanish. As I understand it, the working theory is that black holes gain in mass as they take in mass. If mass is instead, destroyed, then what sustained the gravitational pull of the black hole? Unless there is a core of massless (matter-sourceless) force preventing it from coming any closer that the minimum distance at which the structural integrity of the particle can hold, the matter would be obliterated, and the mass lost. So here is my question. Is there any observable (not theoretical, unless it voids my above reasoning) evidence to show that black-holes gain mass? That is, if they gain mass, net mass would not be lost, so the force of the net gravitational pull of the black hole and the matter between a body and a black hole would remain unchanged. If the mass of absorbed matter is ultimately destroyed, the force towards the black hole at a fixed point would decrease to approach the actual, CONSTANT force caused by the mass of the black hole. Of course, we have no way of actually measuring for this, as this would required a fixed point around a black hole. The only theoretical way I could see to measure this is to have some spacecraft putting out a constant thrust away from the black hole, to measure the force required to REMAIN in the fixed point. Obviously, this can not yet be tested. Is there anything I may have overlooked, either in my theoretical reasoning, or in methods for observing for this phenomenon? Perhaps there are implications this theory would mean that are untrue? Thankyou, Kael.
