Mystery Signal Could Be Dark Matter Hint In ISS Detector

astroengine writes Analysis of 41 billion cosmic rays striking the Alpha Magnetic Spectrometer particle detector aboard the International Space Station shows an unknown phenomena that is "consistent with a dark matter particle" known as a neutralino, researchers announced Thursday. Key to the hunt is the ratio of positrons to electrons and so far the evidence from AMS points in the direction of dark matter. The smoking gun scientists look for is a rise in the ratio of positrons to electrons, followed by a dramatic fall — the telltale sign of dark matter annihilating the Milky Way's halo, which lies beyond its central disk of stars and dust. However, "we have not found the definitive proof of dark matter," AMS lead researcher Samuel Ting, with the Massachusetts Institute of Technology and CERN in Switzerland, wrote in an email to Discovery News. "Whereas all the AMS results point in the right direction, we still need to measure how quickly the positron fraction falls off at the highest energies in order to rule out astrophysical sources such as pulsars." But still, this new finding is a tantalizing step in the dark matter direction.

    You forgot the most realistic and easily proven dark matter theory. It's a math error! If the Star Ship Enterprise can't estimate total matter in the entirety of the universe, I don't think a Xeon can. You have to compensate for billion of years of light delay over an even scale while space is expanding the entire time that the light is traveling through it and be flawlessly accurate on the counts of individual atoms. You get one single thing wrong like mass vs perceived light bending around a black hole and you miss half the miss in every black hole in the universe. If there's a 100% black hole universe, you might have missed the whole damn thing. I mean come on! Oh look, lightning...it must be Zeus! Oh look, a floating thing with a light in the sky...must be aliens coming to visit! Can we go back to science and stick to the most likely explanation for once? Dark matter isn't real!
