No. 106: Jul-Aug 1996
Shortly after Hyakutake's X-rays were announced, a fourth theory of origin was put forth by acknowledged heretics C. Wickramasinghe and F. Hoyle. Comet Hyakutake, they said, was not emitting X-rays itself. Instead, solar X-rays were mirrored in earth's direction by a cloud of very tiny carbon-containing particles released by the comet. Electrons in these nanometer-sized particles acted as if they were free electrons, and these are excellent scatterers of X-rays. Anyone familiar with the writings of Hoyle and Wickramasinghe can guess what these nanometer-sized particles might be: viruses, of course!
"It all fits in the the idea that there are real viruses in comets and that comets are the agents by which life is brought to planets."
