A star explodes and turns inside out

I believe that since iron is much heavier than the other elements in the blast, it would be slowed the least by interstellar interference modes, and would, therefore, be the first to reach the outer fringes of the current blast configuration. It may, also, suggest that the iron core doesn't just "sit there" passively as the mass of the entire star impacts its collective surface simultaneously. The core may "actively" recoil the implosion wave that impacted its surface perfectly spherically. That incoming wave was travelling through less dense surrounding core shells. Once transferred to the solid iron core, its speed would have jumped dramitically as it continued to the geometric center of the iron core itself, thus amplifying the rebound from the focal point at the dead center of the iron core. This amplification is too much for the strong force to bear, and some of the iron converts to pure energy as the atoms disintegrate. Since this wave, now travelling entirely within the entire core, was absorbed by the core at a faster rate than which the collapsing shells could fall into the star's gravity well towards the core boundary, the core would effectively "siphon off" incoming collisional energy momentarily, creating a gap, right at and inside the core/outer shells boundary. This would allow for a momentary pause in the build up of catastrophic pressures which would appear as the "stall of infall" current models predict. But it's not really a stall; it's where the supernova gets its kick. Remember that the incoming shock wave from the collapsing shells already impacted the shrunken iron core, and that wave raced inwards towards the center of the iron core faster than the original wave because of density increase. Then THAT sperical wave imploded into the center of the iron core, releasing pure energy rebounding into the dense medium, and meeting more infalling wavefronts as it races back out of the iron core. These interactions DESTROY the iron core, pulverizing it into Jupiter-sized granules. And these actions all take place as the outer shells are STILL FALLING inwards, in apparent slow-motion, compared to the faster travel time of wavefronts in the denser medium of the iron core. But, those outer shells are collapsing with ACCELERATION, because the "front" of the incoming wave front gets sucked into the iron core FASTER than it could fall! The remaining outer shells obligingly increase their collapse rate for a time. Then, like a grenade that was placed into a vacuum bottle, the supernova transaction takes place. The outer layers collapsing with acceleration into a seeming black hole. The inner core detonating perfectly as pure energy from the absolute center of the iron core turns the core into an expanding bubble from within. When this irresistable bubble meets the immovable inbound shells, we have two systems which are accelerating yet opposing. The iron cannot be stopped on its journey outward, and the outer shells have yet to cease falling inward by sheer momentum. Wherever the two meet, elements heavier than iron are produced, and should be currently located approx. 20% of the distance from the current outer edge and the geometric center of the blast.
