A model of the universe based on energetic spacetime (zero point energy) is expanded. The energy density of spacetime is calculated using only general relativity and acoustic equations. This energetic spacetime is shown to possess the properties required to be the new aether (Lorentz invariance, quantization of angular momentum, impedance, and quantum mechanical energy density.) The contradictory wave-particle duality properties of a photon are resolved by a model where a photon is a wave propagating in energetic spacetime but appearing to have particle properties because it possesses quantized angular momentum. Compton scattering and the photoelectric effect are examined and found to be compatible with the proposed wave-based photon model.
