Bohmped to the top..

(attempting to add italics... If this doesn't work, can someone tell me how to do it?)

Physics is ambiguous about what is real beyond the reality of events.
...
But in [QED], particles are the only reality. Nothing else needs to exist.


Except state, dimension, and the nomological mandates of interaction, all of which are also part of the theoretical model. Moreover, QED calculates the superposition of possible paths for a particle. The probability wave function so derived describes the particle's existence between the pairs of events that form the endpoints of the wave function.

This still leaves the problems associated with wave collapse, the relationship between dimension and the wave function, and how a causal macro structure of the Universe can be derived from an acausal probability wave. I think the answers to the first and last of these lie in complexity theory, but I'm not sure of where the answers to the GR-QM relation springs from.
