Simes is obviously referring to to whether he thinks space is "folded"at the quantum level, which would allow objects and persons to instantaneously travel far distances across space. However, as Simes well knows, the chaotic and seemingly non-deterministic quantum nature of "foldspace" requires at least limited prescience on the part of the human navigator, otherwise the absurdly complex mathematics involved in producing reliable physical projections of such events would only be possible with fourth dimensional computers.
