Scalar Theory of Everything (STOE). The need for a paradigm shift is growing. Many ad hoc models and outlandish speculations abound to model many unexplained observations. The STOE's audacious claim of a new paradigm is supported by corresponding to relativity and quantum mechanics; by explaining many problematical observations; and by making and fulfilling several predictions. It posits 2 components of the universe emerge to form everything. It models the universe as composed as cells with Sources (spiral galaxies) and Sinks (elliptical galaxies and matter). It forms the Universal Equations. One equation to define the potential at all points and one equation that uses the potential to exert forces on the matter. These equations are applied to the microwave background temperature, rotation curves, asymmetric rotation curves, galaxy redshift and discrete redshift, the pioneer anomaly, light interference, etc. The wave model of light interference is rejected by 2 experiments predicted by the STOE. Maxwell's Equations are modified. Life and society application of the STOE principles is suggested.
