Description
Internal spacetime geometry was recently introduced with the aim of modeling quantum nonlocality using degenerate spacetime metrics. Such a spacetime is equipped with a set of worldlines for which time is stationary, that is, worldlines with no interior points. Consequently, the dimensions of tangent spaces vary at points where these worldlines intersect, and a projective measurement of spin or polarization corresponds to an actual projection between tangent spaces of different dimensions. Moreover, the standard model particles can be decomposed into particles with such worldlines using the Dirac Lagrangian. In this talk I will give an overview of this geometric framework, and show how spacetime curvature naturally arises.
