It seems to me that an obvious source of dark matter (and possibly dark energy) might be the massive ejections of spent fuel from our sun in the form of the solar wind. If our sun regularly ejects spent fuel in the form of the solar wind, it follows that the same process must happen in billions of other stars in the Milky Way and across the entire universe. This may sound crazy, but if an approximate mass could be calculated for the amount of material expelled by living stars, it could well be analogous to the amount of so called dark matter we are told is present in the universe. Any thoughts? ad Also, can anyone explain or point to an explanation of the material ejected by the sun in the solar wind, the best explanation I've ever heard is that it's a sort of 'plasma'. We're spending billions of dollars chasing elementary particles around accelerators. Why not use the detector technology at the heart of these detectors on sattelite based instruments capable of detecting and offering science some insight into the particles in the solar wind. If my understanding of the nuclear processes at work within the sun is correct then what is the solar wind but an ejection of sub-nuclear particles. The key point is that the particles in the solar wind are formed in nature and not by man. Shouldn't the objective be to limit the effects of the observer on the observations?
