    Well, the frame dragging phenomenon found in galactic arm structures is
    certainly an indication that gravity propagates at speed of light or
    thereabouts. On a different note, keep in mind that phenomena like
    supernova would not form black holes as they do if gravity did not
    travel in wave fronts at a finite velocity. If gravity propagated
    instantaneously, then massive stars would just magically turn into black
    holes without all the messy explosive effects.

    -- depends on whether or not gravity is limited by time... or rather,
    the resolution of time...
    extend your argument one step further and say that instead of
    supernova's collapsing, why
    not the final state of the universe?

    imho, there's nothing to say that within each step of time, gravity is
    not affecting everything
    simoultaneously... rather, that the effects (supernova, universe
    collapsing/expanding) of gravity
    take more than one time frame...

    its like TRUE quantum computing (not the stuff there working on now,
    qubits etc); if you could
    build a computer that mapped the existing quantum rules of the universe
    within a static shell
    (thus preventing the containing universe from interfering with the
    calculation), there's absolutely
    no reason why you couldn't slurp an infinity in a timestep... it would
    fundamentally break Turings
    theory of computation, in that each step of an algorithm could take an
    infinite amount of time,
    but relative to our frame of reference, finish in a single step....
    really neat if you ask me :)
    of course, try putting it in practice...

    omard-out
