In the first paper of this series, we have introduced the concept of an atom of space-time-matter [STM], which is described by the spectral action of non-commutative geometry, corresponding to a classical theory of gravity. In the present work, we use the Connes time parameter along with the spectral action, to incorporate gravity into trace dynamics. We then derive the spectral equation of motion for the STM atom, which turns out to be the Dirac equation on a non-commutative space.

  1. Proposal for a new quantum theory of gravity III: Equations for quantum gravity, and the origin of spontaneous localisation

    gr-qc 2019-08 reject novelty 5.0 of 10

    A proposed noncommutative matrix action for 'atoms of spacetime-matter' aims to derive quantum gravity, spontaneous localisation, and classical general relativity with matter sources from a single principle.
