The consequences of energy-time-uncertainty

  1. Feb 3, 2005 #1
    There are a lot consequences of this uncertainty. For example: zero-point-energy, vacuum fluctuation with Cassimireffect and that virtual particle become true. Are there any more consequencens?

    And another question ist: When does the uncertainty in position stop?

    In spectroscopy, if the lifetime of an exited state is long (i.e. Delta(t) is large), then the energy state is more well-defined. You see sharp peaks in the spectra.

    There is no definite, well-defined boundary.
