He states, in the words of the professor, his theory, thus: "My theory is that if one of these dark objects chances to strike a star it bursts through its outer envelope and sets free the enormous fires pent up within." These pent-up fires within the sun, he claims, are going to blaze up more furious and be the cause of this dread catastrophe of ruin and death to the sun and planets. With all respect to this eminent astronomer, I insist, first, there are no pent-up fires in the sun. Second, no dark or light star, planet or globe can ever fall into the sun, because the law of electric repulsion in the sun will send it off, as it does the comets, in an opposite direction; besides this same law of electric repulsion will forbid any such object from coming into the solar system. He says this dark star, many times the size of our earth, striking the sun, would destroy it and our earth and planetary system by fire. All life and combustible material, including stones and the surface of the sun and planets, he insists, would be utterly consumed by the heat engendered by such a collision. Now, I contend, in the first place, that such an event is virtually impossible; and if it were possible, a star of many times the size of our earth, coming in collision with the sun, would make little more impression on it than a dozen hogsheads of dynamite thrown against the surface of the moon. Both would do great local damage to the spot and vicinity where they struck, but neither would produce any great general disturbance and injury to these orbs. Many times the size of the earth would mean naturally something like a dozen times the size of the earth. Let us estimate the general result by comparison. The sun is one million three hundred thousand times larger than the earth. It is so large that if we could drop our earth into the center of the sun, our moon, which is two hundred and forty thousand miles from us, would only be about half way to the circumference or outer rim of the sun. Now, a star many times the size of our earth, striking the surface of the sun, would create great heat by the compact, and great distraction in the locality where it struck; and would likely imbed itself in the sun, like large meteors do on the earth, and become a good sized mountain on the sun's surface. It would not increase the electric currents or radiation, of the sun sufficient to melt the snow on the mountains of the tropics or set fire to a haystack on the earth. Its effect on the earth would not be excessive in temperature, and would be very temporary. For my theory is that the sun sends only such currents of electricity to the earth as the earth draws and demands by its opposite polarity.
