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 t₀, the quantum of a moment. Time is the Fifth Fundamental Force emerging from Pure Nothingness N₀ = T⁰, 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/G² and Eₜ=MC/π G², and TIME+SPACE+LIGHT=5D sphere-time. Both theories converge on Time as energy/force. TER extends the paradigm with a source (N₀), Time Density ρₜ, and a unified ontology: Dark Matter = Condensed Nothon, Dark Energy = Flowing Nothon, Black Hole = Pure Nothon concentration. Testable predictions are provided.
