The idea of the time-space continuum (time as the fourth dimension of space) in modern physics means, among other things, that a certain event (the encounter of multiple particles) can be much more elegantly and convincingly explained if we posit that only one particle travels forward and backward in time. This logic involves the static space-time picture described by Einstein: events do not unfold with the flow of time but present themselves complete, and in this total picture, movements backward and forward in time are as usual as movements backward and forward in space. The illusion that there is a “flow” of time results from our narrow awareness, which allows us to perceive only a tiny strip of the total space-time continuum. Is not something similar going on in the alternative narratives? Beneath ordinary reality there is another, shadowy, pre-ontological realm of virtualities in which the same person travels forth and back, “testing” different scenarios: Véronique electron crashes (dies), then travels back in time and does it again, this time surviving.
