On the Two Spaces of Elementary Particles, and Why Wave Functions Collapse

The current formulation of quantum theory is notoriously agnostic about the ontological aspects of the propagation of elementary particles and their interactions. In this brief note, we propose a minimal ontological representation of interactions, based on a micro-cosmological description of the manifestation of these particles in the collapse events of their wave function. The fading of the pre-collapse wave function and the arising of the post-collapse function occur dynamically, as they asymptotically approach different sheets of the same micro-cosmological horizon, whose projections onto ordinary spacetime are placed at finite times.
