I don't think anyone really knows, and so one cannot say that gravitational waves formed by the black hole will not escape the event horizon. Just my thoughts, anyway. |
Hi Neutralino, maybe, but my science study shows GR to only be responsible for 50% of the grvitational force, of light bent, as it passes a star. The other 50% is somewhat as you state, but I do not fully accept GR completely, as Newton's classical physics of gravity can account for the bending of light, just as easily. I also do not accept the seemed validity of spacetime curvature, in the ways generally understood. To me, space and time, time being no more than distance measure of matter in motion, are two distinct elements of physical space/matter and motion. I'm trying to theorize new ways to see the total universe, and do not hold to Einstein's systems' completed, seeming completenesses. I see them as stepping stones to deeper understandings of the physics involved, therefor; I am following the most recent developments of "Double Special Relativity", which the paper on "A Simple TOE", you have referenced also, is the direction my theorizing is going. To me, if there are different frequencies of basic light/em waves, then they must vary in velocity, and not adhere to Einstein's group velocity of unified c, for all wavelengths. Though science has not been able, so far, to distinguish this slight difference of true c velocities, my money is on the fact, the newest experiments will discover these facts. If the experiments prove to be true, then we have a whole new ball game...
As to the mass inside black-holes, I don't see any other possible way for a black-hole to have mass, and an event horizon, without the mass and gravity being most-totally trapped inside it, giving it its present theorized dynamics. If you have a different dynamics of black-holes, please post it. I'll be glad to check it out, as we are all only theorizing, in this most esoteric of areas, but my theorizing tells me, gravity can't extend beyond the event horizon, or there'd be no extreme internal mass capacity, and also, most have speculated, the laws of physics must work in inverse order inside black-holes. I'm not saying the solar systems, in galaxies, or other matter is not attracted to black-holes, but such matter is attracted, to black-holes, by its own gravity fields, acting on the presence of black-holes___and only the external gravitational attraction of matter outside black-holes, is the true gravity attraction... This may seem somewhat confusing, since none of us can yet describe the true gravity waves mechanics, but the dynamics of black-holes and galaxies, IMO, can work in no other way, to preserve the mass and gravity dynamics of both black-holes and galaxies. If black-holes had the extreme external gravity, internal mass would produce, galaxies would quickly collapse... So, my physicist friends agree that black-holes, if existing at the center of galaxies, would require no external gravity, and high mass internal gravity, and I agree with them...
I think this is also in line with Hawking's early ideas of micro black-holes, and his later ideas of macro black-holes... As a further example, people have put it to me this way, we see neutron stars revolving around each other, at extreme velocities, but we witness no black-holes revolving around each other, which could only be seen by the space in front of background light sources, so if two black-holes approached each other, they'd just simply quietly merge, not rotate and collide, as do neutron stars... This is the way I theoretically understand it, anyway...
So, please post your ideas of the same dynamics and geometries...
