Complete Mass Decay and the Volumetric Genesis of Dark Energy

an extended interpretation of Einstein’s equivalencerelation necessitates considering the ultimate fate of mass when its energycontent is fully dissipated, reaching a terminal state characterized by thefundamental properties of the vacuum. In this ultimate limit, complete massdecay is not limited to conversion into photon radiation but extends to theinteraction with, and eventual incorporation into, the metric structure ofspacetime itself.
