"I'm very glad," I responded. He nodded and went back at once to what he had been saying previously. "I'm going to send this into Time. You must understand, Frank, that I can give you now only the fundamental concepts underlying this apparatus. We have so much to do today--so little time for theory. I need only tell you that it is readily demonstrable that Time is one of the inherent factors governing the _state of Matter_. This substance we have discovered--created, if you will--yields readily to a change of state. An electronic charge--a current akin to, but not identical with electricity--changes the state of this substance in several ways. A rapid duplication of the fundamental entities within its electrons--they are, as you perhaps know, mere _whirlpools of nothingness_--this rapid duplication adds size. The substance--with shape unaltered--grows larger. With such a size-change there comes a normal, correspondingly progressive change of Time-rate. We had to go beyond that, however, and secure an independent Time-rate, independently changeable, so that the vehicle might remain quiescent in size and still change its Time. In doing that, the _state of the matter_ as our senses perceive it is completely altered. As you know, no two bodies can occupy the same space at the same time. Which only means that with the Time-dimensions identical, different dimensions of Space are needed. With the Time-dimension differing--the state of Matter is different; two bodies thus can be together in the same space." "What is a Time-dimension?" I asked. "I mean--how can you alter it?" "I would say, Frank, that the Time-dimension of a material body is the _length_--or a measure of the length--of its fundamental vibration. Basically there is no real substance as we conceive it--for all Matter is mere vibration. Let us delve into substance. We find Matter consists of molecules vibrating in Space. Molecules are composed of atoms vibrating in Space. Within the atoms are electrons, revolving in Space. The electrons are without substance, merely vibrations electrically negative in character. The nucleus--once termed proton--is all then that we have left of substance. What is it? A mere vortex--an electrical vortex of nothingness! "You see, Frank, there is no real substance existing. It is all vibration. Motion, in other words. Of what? That we do not know. Call it a motion of disembodied electrical energy. Perhaps it is something akin to that. But from it, our substantial, tangible, material universe is built. All dependent upon its vibratory rate. And the measure of that I would call the Time-dimension. When we alter that--when through the impulse of a current of vibration we attack that fundamental vortex to make it whirl at greater or lesser rate--then we, in effect, have changed the Time-dimension." There was so much that seemed dimly close to my understanding, and yet eluded me!
