Abstract
IT may be profitable in relation to current paradox to inquire very briefly into the relation of time to space. Consider two adjacent localities, one around a centre P and the other around a centre Q. The familiar conical diagram asserts that for any sub-locality that is within a certain cone centring on P the relative time is real, while outside that cone it is pure imaginary; and likewise for a cone centring on Q. These cones intersect: and there are regions R, inside one of them and outside the other, for which time is real in relation to P and imaginary in relation to Q, or, in current language, the region around R is time-like in relation to P but space-like in relation to Q. This is something far more complex than the properties of a simple continuum such as a practicable space.
