    This is also my view , that gravity being instantanious gives an unbeatable
    method of information transfer. That is of course depending on the propgation
    speed. Everything I have read thus far states that the propogation is
    istantanious. I do have some serious worries about this and will closely watch the
    results of any experiments that are performed.
    The only way I can easily except that the propogation is instananious, is
    that every particle in the universe that exerts gravity. Is entagled with every
    other particle. I can 'kind of' except this, baring in mind that all the
    particles came from the sub-atomic soup that existed pre big bang.

    I did spend a few brain cycles on a possible experiment utilising the
    apparent ability of cryogenic superconducters to reduce gravity. I didnt get very far
    due to the math and the constant nagging in the back of my mind that if we
    mess around with gravity, we also mess with time and have to somehow factor this
    into the eqautions.
