Awh, what are you trying to do here :) Giving me a headache?

If Feynman paths is correct then it invalidates most of what we experience at a every day level. For example there are no photons traveling from the sun to us, and every photon takes every possible path which in fact means that one photon fills up our universe. And how do we get away from that? By saying that they are 'probabilities' :) huh.

Which to my eyes comes very near 'parallel universes' as well as 'many paths universes'. It all seems reasonable but the implications gives me a headache. And if to that add the idea of time as being just 'spacetime intervals' that is not a flow but distinct static 'frames'?

Nah.. However much I like Feynman I wonder what kind of universe his ideas leaves us with.
