The Time-Light Equivalence Principle: $c$ is Not Speed of Light, $c$ is Speed of Time \ Light = Manifestation of Time, Time at $c$ Becomes Nothingness $T_0$

We propose Time-Light Equivalence Principle: $c$ is not speed of photons traveling through spacetime, $c=v_T$ is constant speed of Living Time $T_L$ itself within Physical Universe Domain. At $v=c$, Time generates Light, Light is Time rendered visible, and Time reaches its own singularity $T_0=N_0$ (Nothon Phase / Nothingness). This redefines $c$ as fundamental constant of TER and explains four pillars: (1) why $c$ is absolute limit, (2) why photon has zero proper time, (3) why $E=mc^2$, (4) why black hole traps light. Mass is condensed time $M_T$, $E_T=M_T v_T^2$, Black Hole is $T_0$ domain where $v_T\rightarrow 0$. Time Is Light, Light Is Time Becoming Nothingness.
