A proof of the gravitational dynamics developed here-in is LIGO’S Sept. 14, 2015 detection of a “gravity wave”, and a proof of the nature of the evolving continuum is IBEX failing to find a shock wave at the edge of the heliopause and the “dead zone” discovered by Pioneer 1. This is a Time Dilation-based cosmology. The evolution of time is the primary, irresistible, force in the universe, as all events in space must evolve forward with time. This is the Fundamental Direction and Rate of Evolution, herein represented by Einstein’s Fundamental Metric, which is the basis of the tensors describing a null gravitational field. Fluctuations in the CMB are fluctuations in the rate of time. When a standing wave forms a dilation pit, we also see an irresistible Gravitational Direction and Rate of Evolution. Dilation creates a density at the faster end due to contraction to maintain c and an increase in energy and pressure due to an increase in frequency. Gravitational evolution translates the fundamental energy of time into kinetic energy. When the gravitational evolution impedes at the central focus of a spherical dilation pit, the kinetic energy is translated into thermal energy. The resultant of the FDE & GDE is the curvature in evolution we see as the spacetime/quantum continuum evolves forward. We have 2 event horizons we appear to evolve between where time appears to stop, “Limits of Relativity”. We apparently evolve toward the event horizon of the galactic MECO (“black hole”) and away from the outer, cosmic, horizon. The passage of proper time within our own inertial frames has an acceleration aspect of ~2.2686*10^-18 s/s that manifests the Hubble shift through time dilation in older frames and time appears to stop at ~13.9 Gly looking outwards. This acceleration eliminates singularities and infinite expansions when added to the time elements of Einstein’s field equations. Each galaxy can be considered a branching of the evolution of the universe. Both of these event horizons retreat when approached and the dilation gradient shifts, so if the 1 s/s limit is considered the edge of the universe, MECO’s are gateways to other universes without end. The proof that the ~2.2686*10^-18 s/s acceleration in the inertial frame exists is in the fact that life forms grow up, against the GDE (gravity). Galactic rotation velocities are explained. The origin of spacetime is explained. This model replaces LamdaCDM/Big Bang.
