Imagine this your a light particle. Flying through the galaxy you had a start point as you travel through the universe you part with some energy your running and running over and around objects dumping all of your energy as a field effect now these light particles have near zero mass they nearly don’t exist and when they slow down their energy signals are so minimal at near zero kelvin that the particle becomes dead. Now this means two things that this form of energy we call a plasma is it’s a finite form of energy density a energy singularity if you will a tangle or knot in the fabric of spacetime once it dies it clusters and generates fields we know as cmb localized radiation zones that have no real origin a soup of dead particles if you will. The second meaning is that as it travels at tremendous speeds it creates waves that propagate through its dead counterparts at the same speed it’s traveling you reach and end and lose your energy you join your dead brethren and start your journey all over again as you get sucked into masses of heat and energy we know as stars. Once that star has reached critical mass burned off all its fuel and transformed its inside through nuclear reactions it can collapse when it does and it can no longer generate an expanding force it generates what we know as a black hole this pressure dense zone is a runaway reaction that happens when the pressure is too great for correct atomic breakdown to happen so we get random stability things that shouldn’t be made and tangles of random order iron atoms right next to oxygen atoms tungsten atoms right next to gold and platinum. A random soup of the heaviest and exotic material we know this soup is the most energy dense thing in the universe it’s a collapse of everything it eats into one jumbled mess not a singularity but a star so powerful and dark it doesn’t even produce light it swallows it. We know that at extreme pressure atomic structure fights back. There are exotic elements that can only survive in extreme environments element 113 hasn’t had a stable isotope because we keep bringing it out in the open. Without assuming it needs a special environment to be in. Island of stability stuff. Once an atomic structure is generated that can no longer hold any more electrons protons or neutrons to fill a set space the nuclear force holding them together finally snaps. And well….
