Modern physics has developed the theory that all matter consists of minute waves of energy. We know that the number of radio and television impulses, sound waves, ultra-violet rays, etc., that may occupy the very same space, each solitary upon its own frequency, is infinite. So we may conceive the coexistence of the infinite number of universal, apparently momentary states of matter, successive one after another in consciousness, but permanent each on its own basic phase of the progressive frequencies. This theory makes it possible for any event throughout eternity to be continuously available at any moment to consciousness.

Space in any form is completely measured by the three dimensions. If the fourth dimension is a physical concept and not purely metaphysical, through what medium does it extend? It is not through space nor time that the time machine most approved by science fiction must travel for a visit to the permanent prehistoric past, or the ever existent past fantasy future. Three seconds flat is the usual time, and the space is crossed by moderate mileage, while the overwhelming immensity of such journeys must be conceived as a static pulsation through an enormous number of coexistent frequencies which perpetuate all events.

The body, senses and brain, in common with all matter, have their counterpart on each of a countless number of frequencies. The senses in each counterpart bear the impression only of phenomena that share its own frequency, whereas those upon all other frequencies are invisible, inaudible and intactible to them. Consciousness is the factor that provides the progressive continuity to sensory impressions. When consciousness deserts the sleeping body and the wakeful world, it continues in the myriad progressions of the ever-present past and future, in a life as vibrant and real as the one left when the body tired and required sleep.
