The Duality of Time Theory

Branching space-time theories resemble the many worlds interpretation; however, the main difference is that the they take the branching of history to be a feature of the topology of the set of events, with their causal relationships, rather than a consequence of the separate evolution of different components of a state vector. In the many-worlds interpretation, it is the wave-functions that branches, whereas in in this theory the space-time topology itself branches.

The branching space-time theory has applications to Bell’s theorem, quantum computation and Quantum Gravity, and it has some resemblance to hidden variable theories and the ensemble interpretation, since it considers particles to have multiple well defined trajectories at the microscopic level. These trajectories can only be treated stochastically at a coarse grained level, in line with the ensemble interpretation.
