Just spent a few hours drinking tea and thinking about this nova. n other threads I've mentioned a graviton and a photon sitting on a planet, talking about stuff. Let's park them in orbit round this super massive sun. The photon will point to where the sun had been, the graviton will point to where it is. The graviton will do a spot of calculus and give the photon a pet lip by casually throwing the photon's universe into the bin. The speed of light is a little bit of the speed of gravity. The graviton is right to dump it. Then the photon says that he/she sees a big glowing ball, the graviton shakes his head in utter disbelief. He sees only the Swartchild radius of the star. Pretty small, about 2000 km diameter.
Now, if we say that any bit of mass gives over half its energy to creating its own space; energy that we can't see; so we double the mass of the particle. Now that's the e.m mass, the particle spins at the speed of light and has an angular momentum of h but we can have a gravitational mass, where the particle spins at the speed of gravity, with an angular momentum of one. This thing is not in our space it's in a phase changed space. In its space it behaves like whatever particle it is in e.m space. However, any interactions it has with e.m space are going to be negative refractive index interactions. It would be like looking in a reversed mirror and seeing that the guy facing you wears his wedding band on the left hand, just like you do. Note that this isn't reverse time, or negative mass. I grant you it's pretty weird though.
Righto, the asteroid belt. It's differentiated, so it looks very much like it was a planet that exploded. I did say to Larry that the only way that I could see the core of a gas giant being totally destroyed is if the force of gravity just switched off. Then the planet would explode like a fizzy pop bottle. Well, we now have a nova where the core has exploded. Gamma rays collide and produce electron/positron pairs, that's effectively switching off gravity.
Consider a soft gamma ray as a particle which has a rest mass of about 6E-64 kg Then it's gravitational mass will be the electron mass. A huge amount of energy packed into a tiny Swartchild radius. Two gamma rays hardly ever collide core to core.
In a planet, even a massive one, the Swartchild radius is tiny. Suppose it could alter slightly, then electrons in gravitational space would find themselves in e.m space and have to dump their energy. We're talking centimetres here. The planet vapourises, wow! The wow is because a super massive tiny core could still be out there.
One thing to note, this star nova has to be very low on heavier elements, metal stops gamma ray production presumably. Though I contend, gravitons don't see anything in e.m space, if they have to give up any of their energy into e.m space it's in little packets of h, to it, but pretty big stuff to us in em. space.
