He felt again the commingled agonies of interdimensional acceleration. He perceived again the formless, textureless, spaceless void of blankly gray nothingness which was the three-dimensionally-impossible substance of the tube. A moment later, he felt a new and different acceleration--he was speeding up _inside the tube_! Then, very shortly, he felt nothing at all. Startled, he tried to jump up to investigate, and discovered that he could not move. Even by the utmost exertion of his will he could not stir a finger or an eyelid. He was completely immobilized. Nor could he feel. His body was as devoid of sensation as though it belonged to somebody else. Worse, for his heart was not beating. He was not breathing. He could not see. It was as though his every nerve, motor and sensory, voluntary and involuntary, had been separately anaesthetized. He could still think, but that was all. His sense of perception still worked. He wondered whether he was still accelerating or not, and tried to find out. He could not. He could not determine whether he was moving or stationary. There were no reference points. Every infinitesimal volume of that enigmatic grayness was like each and every other. Mathematically, perhaps, he was not moving at all; since he was in a continuum in which mass, length and time, and hence inertia and inertialessness, velocity and acceleration, are meaningless terms. He was outside of space and beyond time. Effectively, however, he was moving; moving with an acceleration which nothing material had ever before approached. He and his vessel were being driven along that tube by every watt of power generable by one entire Eddorian atomic power plant. His velocity, long since unthinkable, became incalculable. All things end--even Eddorian atomic power was not infinite. At the very peak of power and pace, then, all the force, all the momentum, all the kinetic energy of the speedster's mass and velocity were concentrated in and applied to Kinnison's physical body. He sensed something, and tried to flinch, but could not. In a fleeting instant of what he thought was time he went _past_, not through, his clothing and his Lens; _past_, not through, his armor; and _past_, not through, the hard beryllium-alloy structure of his vessel. He even went past but not through the N-dimensional interface of the hyperspatial tube. This, although Kinnison did not know it, was the Eddorian's climactic effort. He had taken his prisoner as far as he could possibly reach; then, assembling and concentrating all available power, he had given him a catapultic shove into the absolutely unknown and utterly unknowable. The Eddorian did not know any vector of the Lensman's naked flight; he did not care where he went. He did not know and could not compute or even guess at his victim's probable destination. * * * * *
