Here is a hypothesis: the singularity inside a black hole may represent a real physical energy state rather than being only a mathematical boundary in general relativity.
My idea comes from thinking about black hole mergers. If two black holes merge into a larger black hole,then conceptually their singularities merge into a larger singularity.
This made me question whether the singularity could actually be an extremely concentrated energy structure rather than simply an undefined point in spacetime equations.
In this hypothesis , photons and energy falling into the black hole continue contributing to this internal concentration of energy over time.
Therefore , black hole mergers may not only combine mass externally , but also these internal "energy singularities" into one larger unified state.
I developed this idea further in a short scientific booklet titled "The Photonic Singularity" currently available on Amazon kindle.
I am not presenting this as a replacement for accepted physics, but as a conceptual attempt to think about what singularities may physically represent beyond the current mathematical breakdown of the equations.
I would genuinely appreciate criticism, feedback, or guidance from people with more experience in relativity, black hole physics,or quantum gravity.
