We only really see things that change and then we deduce how things are from how they change. It then seems reasonable that the universe is made up of not only things that change, but also things that are. Single photon resonances are the things that are and make up all change and single photon resonances occur between emitter precursors and absorber outcomes. Single photon spectra make up the fundamentally discrete nature of the universe with emitter and absorber chromophores.
A single photon resonance between emitter and absorber chromophores exists as a cosmic time packet that grows and then decays, which defines its time packet. Atomic time and space emerge from the quantum oscillations of that photon burst from the speed of light and its wavelength. The growth and decay of the photon packet define its location and direction and result in the Lorentzian spectrum that this example shows. The arrow of time emerges as the direction from primordial emitters to black hole absorber destiny outcomes.
The universe itself is then a spectrum of aether whose exponential decay defines not only a cosmic time, but also defines charge, gravity, and all forces along with the quantum oscillations from which atomic time and space emerge.
