Underground Lab To Probe Ratio of Matter To Antimatter

Wired reports on the Enriched Xenon Observatory 200, a particle detector scientists hope will answer the question of why there is significantly more matter than antimatter in the universe. Quoting: "The new detector will try to fill in the picture, determining basic features of [neutrinos], like their mass and whether or not they, unlike almost all other particles, are their own antiparticles. That quirk is why some scientists believe neutrinos could be the mechanism for the creation of our matter-filled universe. Almost all other particles have an antiparticle twin that, if it comes into contact with the particle, immediately annihilates it. But if neutrinos are their own antiparticles they could conceivably be knocked onto matter's 'team,' thereby causing the cascading win for matter over antimatter that we know occurred. As the Indian theoretical physicist G. Rajasekaran put it in a speech [PDF] earlier this year, neutrinos that are their own antiparticles would explain 'how, after [the] annihilation of most of the particles with antiparticles, a finite but small residue of particles was left to make up the present Universe.'"

      Neutrinos are gay?

    If these particle detector scientists watched TNG, they'd know that there's only one ratio of matter to antimatter.

    If they're not careful they'll lose anti-matter containment and open up a rift in the space-time continuum.

    Dear citizens and members of the galactic Economic Council

    The rumors about a shortage of antimatter to fuel or spacefleets and habitats is unfounded.

    Everyday our scientists everywhere in this universe are finding new ressources, new anti-black stars to drill for our energy.

    We used antimatter for thousands of millenia now, will continue for a lot more. I am happy to announce you the we finally opened for production that galaxy on the outer left reach of the milky way. There most advanced civilisation is a monkey like tribe that have barely learned to cover themselves and there was so to speak no Spaceflight activities to be observed.

    One or two derelicts spacecrafts have been observed, but they use a primitive explosion system, so we are sure those Terrans will not mind if we pump their galaxy dry of the stuff.
