    Updated: 2010-06-30 15:19:15
    The Copernican principle is a guiding foundation of cosmology. In short, it states that we are not in a privileged place in the Universe. A “random” observer will see the same Universe that we do. The cosmological standard model does satisfy this principle in space: at this moment, any other observer in the Universe should [...]

  • MiniBooNE results suggest antineutrinos act differently

    Updated: 2010-06-18 18:41:32
    Like another neutrino result earlier this week, the MiniBooNE experiment has found that antineutrinos, which should follow the same rules as neutrinos, might oscillate in a slightly different way. The results seem to favor a much-debated antineutrino result obtained by the Liquid Scintillator Neutrino Detector experiment in 1990.
