    in my way of thinking which has not been shaped or refined by a
    college Degree in astro physics. 

    let us say a large comet composed of mostly ice along with other
    detritus and stuff found though out the cosmos gets pulled into a
    black hole at the center of a galaxy, The comet goes in as mainly
    frozen water, for the sake of this discussion entering the black
    hole as water in frozen form is what should " matter " ( HA). what
    that ice becomes when it is inside the black hole and changed by the
    effects of all that gravity is merely a process of what has to
    happen to the water ice of the comet for that "matter " to go
    through the compression process . 

    For the more practical purposes of presure curing investment i am
    unsure, if water cannot be compressed at the pressure being used for
    this process. i am quite confident that some sort of expeiment could
    be devised to prove if the process of presure curing investmest has
    an effect to produce improved castings or not, which was my point in
    my original comment reply to the thread and not the theory that water
    can or can not be compressed 

best regards goo
