  The problem of how to interpret quantum mechanics has persisted for a
century. The disconnect between the wavefunction state vector and what is
observed in experimental apparati has had no shortage of explanations. But all
explanations so far fall short of a compelling and complete interpretation. In
this letter, I present a novel interpretation called dynamic histories. I show
mathematically how quantum mechanics can be reinterpreted as deterministically
evolving dynamical world lines in a 5D universe. Quantum probabilities can be
then be reinterpreted as stemming from ignorance of the state of our own world
line. Meanwhile, the lack of observed superposition in experimental apparati is
explained in that we only live on a single history with a definite set of
properties. Hence, superposition is not an actual state of a particle but a
model of ignorance as in classical probability theory. This explains nonlocal
effects without superluminal communication. I also discuss how this relates to
5D Kaluza-Klein theory.
