Prior to this, the energy represented by these events had been stored in heavy atoms, ever since the time that gravitational potentials transforming energy in the collapse of long-destroyed stars created these atoms, and in doing so, stored the energy within.
Gravitational potentials transforming energy in the collapse of long-destroyed. This was ever. Stars created these atoms. Stars in doing so, stored the energy within. The energy represented by these events had been stored in heavy atoms since the time this. This was prior to this.
