    Often, initial reports suggest some great breakthrough but this one is special:
    Source: Scientists attempt to see a vast, invisible universe - CNN.com

    Replication of this experiment is important but this initial report sounds very encouraging. It makes returning to the moon worth while or at least putting an array of similar observatories on the moon with perhaps a telemetry relay satellite for the far-side data.

    The moon is important because it has a fixed rotation relative to the earth. This means the part of the sky occluded by the earth can provide high resolution of incoming particles. Let it orbits fast enough that events lasting several days can be mapped.

    How long will it be between dark matter being detected and it being taxed?

    I've had an idea batting around, for a few decades. It's likely as watertight as a sieve, but still, maybe it's useful as an analogy. Say, like the concept that our sun "rises" and "sets". Anyway:

    What if everything's expanding?

    Expanding proportionally, in such a way that the relationships between objects is constant, ie: a ruler on a desk continues to be the same "size". And what with this expansion, what we experience as "gravity" is in fact inertia, the effect of being pressed against the earth as it expands.

    Yeah I know, why are the moons orbiting planets, the planets orbiting the sun, and so on. Anyway, a nice meditation exercise. ;)

    i'm waiting for member 'dark doesn't matter' to weigh in on this...

    Not only is the Universe still expanding, it's accelerating! Dark Energy & Dark matter, what part do they play in this Cosmic question?

    And then there is Dark Lightning which is apparently causing the creation of gamma rays and positron anti-matter particles inside ordinary thunderstorms on earth:

    Well yeah, and if the matter itself is expanding, there you go, gravity explained. Next question? ;)
