Has the Payload for Antimatter Matter Exploration and Light-nuclei Astrophysics (PAMELA) mission detected signs of antimatter other than the gravitational effects? There is speculation that the mission may have. Read more here:
MACHOs, WIMPS, Neutrinos, photinos, quarks, squarks, Leptons, Gravitinos, Gluons, Zinos, Higgsinos and more. HEY all that stuff and some of it may account for dark matter. Now we only have three times as much "stuff" again to find - I mean Dark Energy (anti gravity) gets interesting....
The other important question is how they come up with the acronyms for these missions and how absurd are they going to get? Anti Neutrino Detection Electron Response Survey Of Noise?
