Existence and the interpretation of infinite uncertainty?

  1. Nov 22, 2011 #1
    The trade off in uncertainty in momentum vs position in the HUP leaves me
    confused.

    In the context where the momentum is measured to increasingly greater precision and
    consequently position becomes less refined, is any logical inference made about the
    existence of the object i.e. is it less less likely to actually be in existence since it is
    convergng to an infinite uncertainty on exactly WHERE it exists.

    Similar logic could apply to the Energy-time uncertainty relation.

    OR

    Do we reason that the object exists because it has momentum measured to to higher
    and higher precision, but just where it has that momentum is increasingly unknown.

    Yet I would have thought that an object that is becoming infinitely less precise in
    having a momentum property AT a position in space is testing the limits of being a
    physical object at all.

    Does uncertainty converge in any situation which reaches a known limit such as
    for example at the planck scale.

    Also i'm assuming the HUP has relativistic versions?
