"Comets there are in our galaxy, as you know, comets that revolve in irregular orbits about various of our stars, and which have been familiar to us always. A comet, as you know, consists of the coma or head, the nucleus, and the tail. The coma is simply a great globe of electrical energy, with a hollow space at its center. The nucleus is all the comet's solid matter, a mass of meteoric and other material hanging in the hollow at the coma's center. The great coma blows from its own electrical energy, and is driven through space by the release of some of that energy backward, through the vast tail, which is simply released energy from the coma. It is the great coma that makes a comet deadly to approach, since any matter that enters its terrific sea of electrical energy is converted instantly into electrical energy likewise, changed from matter-vibrations to electrical-vibrations, annihilated. Our interstellar navigators have for that reason always avoided the comets of our galaxy, while never has it been dreamed that a comet might exist in empty space outside our galaxy. "Now, however, our astronomers have found that this crimson spot of light that has appeared in the outer void and has puzzled us for days is in reality a giant crimson comet of size and speed unthinkable, which is racing straight toward our galaxy and will reach it within a few more weeks. _And when it does reach it, it means the galaxy's doom!_ For this gigantic comet, greater by far than any of the galaxy's greatest suns, will crash through the galaxy's swarm of stars like a meteor through a swarm of fireflies, annihilating those in its path by absorbing them and their worlds into the terrific electrical energy of its mighty coma; disrupting all the finely balanced celestial mechanism of our universe and sucking its whirling stars into its deadly self as it smashes on; engulfing our suns and worlds in electrical annihilation, and then racing on into the void, leaving behind it but the drifting fragments of our wrecked and riven universe!
