The_Photon_as_the_Quantum_of_a_Moment___Comparative_with_5th_Dimension_Time_Energy_Hypothesis___TER_v3_8

We propose that $c$ is not a speed through space but the rate of Time itself. Light is Time made visible. The photon is defined as $t_0$, the quantum of a moment. Time is the Fifth Fundamental Force emerging from Pure Nothingness $N_0 = T^0$, with its quantum particle Nothon. This paper presents TER v3.8 and conducts a comparative analysis with an independent 5th Dimension Time-Energy hypothesis proposing $T=C/G^2$ and $E_t=M\_C/\pi G^2$, and TIME+SPACE+LIGHT=5D sphere-time. Both theories converge on Time as energy/force. TER extends the paradigm with a source ($N_0$), Time Density $\rho_t$, and a unified ontology: Dark Matter = Condensed Nothon, Dark Energy = Flowing Nothon, Black Hole = Pure Nothon concentration. Testable predictions are provided.
