"In the next days, however, Dr. Whitely continued to study this new vibration, and endeavored to trace it accurately to the sun by using recording instruments which recorded it as strongest or weakest in various quarters of space. By means of these instruments, he was able to plot the course of this force-vibration or ray in space, to chart the path of its strongest portion in space. And by doing this he found that this new force-vibration, contrary to his expectations, was not being radiated out equally in all directions as one might expect. It was being shot forth in a great force-beam or ray, one which cut a straight path across half our solar system! And that mighty force-ray, whose weaker reflected pulsings only struck his instruments here on Earth, was not being generated and shot forth by the sun, but was _striking_ the sun! And tracing its path out across the solar system by his charts he found that the great force-ray was being shot out from the planet Neptune, was stabbing across the great gulf from Neptune, the outermost planet, and striking the sun! "And it was that giant force-ray, as Dr. Whitely and I soon saw, that was and is making our sun's rotatory speed steadily increase! For that great ray, as we found, is one that can stab across space and strike any object with terrific force, as though it were solid and material! You know that even light rays, light vibrations, exert a definite pressure or force upon the matter which they strike. Well, these force-vibrations, of greater wavelength than the light vibrations, also exert pressure and force upon any matter which they strike, but they exert an infinitely greater pressure, can stab across the vast void and strike any object with colossal and unceasing pressure. In this way, then, this great force-vibration or ray hurtles across space and strikes all matter in its path with terrific force, as though a solid arm were pushing across the gulf. "And this terrific ray of force, stabbing in through the solar system from Neptune, was striking our sun just at its edge, just at its limb, at its equator. It struck that edge turning always away from Neptune, and striking that turning edge of the sun with terrific force as it did, the great pushing ray made it turn even faster away from Neptune at that edge, made the sun turn faster and faster! Pressing always upon the turning sun's edge with the same great power, this mighty force-ray has made the sun rotate faster each day, has made its rotatory speed increase by the same amount each day. And since that great ray is still stabbing across the gulf from Neptune to the sun, is still accelerating the sun's spin, it is to that ray that we will owe the division of our sun into two parts, 137 days from now, and the consequent wrecking of our solar system!
