Ed, I am gathering from Chris' conclusions from your post that you've mixed up visible light with gamma rays as sources of neutrons because they are both radiation? Best wishes, Doug my original below: Hi Ed, I am trying to understand what you mean to say. Please bear with me and tell me what I'm missing: The energy of the photons we see in visible light, whether from meteors or a night light or Sunlight on the porch is the same (per discrete photon) we see. There is no upper limit for the energy content of a "photon", and any finite proces has an energy associated with it. In other words, a generic 'photon' can release anything requiring any energy, and anything releasing energy releases "photons", so I can't follow what you mean by "It turns out photons can...". In fact saying a "photon" can do something is just like saying a certain energy can do something -nothing new here, if it weren't true, nuclear fusion and fission, two observable processes would be impossible- as all processes have an associated energy, including warming my hot chocolate to 80 C with infrared "photons". The energy is proportional to the inverse of the wavelength of the "photon". So it is simple arithmetic to calculate the wavelength of a "photon" capable of atomic fission - which is what you are discussing (more specifically deuterium fission)...which is the same photon energy than is released on deuterium fusion. Although the incredible Hulk is green, the photon of green light (wavelength nearly measurable at = 0.00055 millimeters), the most average light, has ten thousand times less energy per "photon" than gamma "photons". Gamma radiation in the neighborhood of the spectrum you are discussing, in fact, is a result of nuclear fission explosions, and has a wavelength shorter than any distance between atoms (no surprise since it is the amount of energy that interacts with atomic nuclei). Until one can mathematically derive or experimentally determine whether such energy present in gamma 'photons' (and energenitic gamma photons at that) can be generated and applied to a little deuterium atom somehow, from all these impacts on Earth, the status of the theory is the same as the status of the Hulk comic character! I am the first to respect a thought experiment: But what scientific experiment could you propose (or has one already been done?) to follow through? On the other hand, if all of the big impact sites are creating all of these radiation byproducts, the least of which is 14-C, would likely create radioactive waste dumps at every major impact event site - a measureable quantity. Has this been seen at Canon Diablo? An observation of that would support your theories. I don't believe any radioactivity has been deduced from any of the impact sites, and this is a subject very interesting to look for by the best military satellites of the most enthused nations. I suppose a new extinction theory can be - the radiation released from ground zero and into the atmosphere was extremely short lived, intense and conveniently left no trace detected yet, but clearly could be responsible for the great dyings in geological history for suceptible creatures. Just need a little clarification, Thanks, Doug > ----- Original Message ----- > From: "E.P.
