What is a “scalar wave” exactly? Scalar wave (hereafter SW) is just another name for a “longitudinal” wave. Scalar physics concerns itself with potential and superpotential fields that do not necessarily give rise to magnetic or electric force fields, yet still have meaningful effects. All this definition is saying is that a vector field is conservative if it is also a gradient vector field for some function. It is possible to measure scalar fields, using Kirlian photography. While there are many choices for the matter fields and for their interac-tions, the simplest actions to deal with in the framework of a lattice model for gravity are the ones that represent one (or more) scalar fields.
