    That's just about right. At the 'bottom' of a black hole the
    gravitational pressures are incomprehensible. We are not even talking
    in terms of trillions of pounds per square inch; we are talking of a
    'place' where atoms and molecules don't even exist- just a sort of
    soup of pure energy which was once atoms and molecules. The ultimate
    statement in science says that atoms cannot be either created or
    destroyed, but only transformed from one form of energy to another. 

    Example: when light strikes a real black surface, it doesn't just
    vanish; it converts to a lower frequency - heat; which can be
    detected with instruments but not our eyes. 

Cheers for now,
