Hello,
Just sharing further work on my planck scale quantum gravity model.
This is a 2d representation of a planck scale dirac spinor (a fermion - like an up quark. Massless, relativistic), that solves for the stress-energy tensor.
In particular the T00 term of the tensor is the conserved scalar quantity that is then used to model gravity. The T00 gets used in the poisson equation to relate to gravitational potential. Then from here, since you have both Tmunu and Gmunu you can fulfill the Einstein Field Equation.
I am working on getting this model into a Wolfram notebook - it may be a few days. But I will update when I do.
Just a note - the gaussian looks elliptical. It isnt - thats just an artifact from the image creation.
