Does Null Physics consider quantum mechanics (QM) and general relativity (GR)?
Yes, QM and GR cover a lot of theoretical ground and both contain quite a few different premises. What Null Physics claims is that all of the phenomena described by QM and GR are the product of a single deep geometry. Null Geometry is nonlinear and four-dimensional, as opposed to the 10 or more dimensions advocated by string theories. Null Physics requires fewer dimensions than string because it isn’t built on top of QM or GR, but lets them form their own basis.
