**An Over-Arching Theory of Dark Energy, Inflation and Black Holes
**

**Abstract**: We derive two new equations of quantum gravity and combine them with reinterpretations of previously proposed concepts of dark energy, black holes, inflation, the arrow of time and the characteristic energy at which rest-mass first manifests itself into a theory which may be a first step toward a comprehensive description of all these phenomena. The resulting theory also predicts new tests, which can be experimentally checked within just a few years. The two new equations are: A) a creation equation to give stimulated emission for any surface filled with gravitons, pulling energy from a background, and B) the association of an outgoing soliton wave of gravitons, a “shell front” with a large Lorentz factor derived from the uncertainties in both space and time. We model the background as a strong gravity brane, a Planck length apart from our brane in a fifth dimension. These new equations are combined with the common notions of an all-pervasive background of gravitons at the Planck limit, the “Planck sea”; the identification of the thermodynamic limit with the emission of gravitons in a “shell front”, i.e. what is usually called the entropy of black holes is identified with the outgoing gravitons; the concept of black holes as a membrane full of gravitons at a large Lorentz factor, the “Planck shell”; the emission of gravitons created in a “horizon shell” during inflation, which lose energy adiabatically with the Planck time. These equations result in stimulated emission of gravitons by interaction with the background, the “Planck sea”, to describe dark energy, black holes, and the inflationary period of the universe. These proposals lead to gravitational waves constituting dark energy. These waves should be detectable within a few years with pulsar timing arrays. The extremely high, but finite Lorentz factor for signal propagation may be expected to have further consequences in particle interactions.
