Main Question or Discussion Point

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.

And another question ist: When does the uncertainty in position stop?
There is no definite, well-defined boundary.
