A variation of this hypothesis assumes that the reflection is due to swarms of meteors doctor who 2005 2014 about the sun, in the plane of its equator, all the way from its immediate neighborhood to a distance exceeding that of the earth. The extension of the corona in 1878 did not resemble in its texture the Zodiacal Light. From the fact that atoms are compound bodies made up of corpuscles at doctor who 2005 2014 a thousand times smaller than the smallest known atom - a fact which astounded most men of science when it was announced a few years ago - a new hypothesis has been developed concerning the nature of the Zodiacal Doctor who 2005 2014 (as well as other astronomical riddles), and this hypothesis comes not from an astronomer, but from a chemist and physicist, the Swede, Svante Arrhenius. The manner in which this pressure is believed generally to act was there sufficiently explained, and it only remains to see how it is theoretically extended to the particles of matter supposed to constitute the Zodiacal Light. In the vast laboratory of the sun it is but reasonable to suppose that similar processes are taking place. Negatively charged corpuscles, it is known, serve as nuclei to which particles of matter in the ordinary state are attracted, and it is probable that those emitted from the sun immediately pick up loads in this manner and so grow in bulk. If they grow large enough the gravitation of the sun draws them back, and they produce a negative charge in the solar atmosphere.
