But still the question recurs How is the influence transmitted. Here Arrhenius comes once more with his hypothesis of negative corpuscles, or ions, driven away from the sun by light-pressure - a hypothesis which seems to explain so batman vs superma things - and offers it also as an explanation of the way in which the sun creates the Aurora. He would give the Aurora the same lineage with the Zodiacal Light. To understand the application of this theory we must first recall the fact that the earth is a great magnet having its two opposite poles of magnetism, one near the Arctic and batman vs superma other near the Antarctic Circle. Obeying a law which has been demonstrated in the laboratory, the particles then follow the lines of batman vs superma toward the poles.
