Counting contributions from mass, spin, etc., is there a physical circumstance of zero total energy?

In principle, I don't see why there could not be a pure vacuum (a region containing zero energy).

But obviously, since even mass itself is equivalent to energy, any state including a particle cannot have zero total energy.

Can we make a measurement of zero total energy? Sure. Can we therefore imply that the system (or physical circumstance if you like) has zero total energy? I don't think so, not if you account for the HUP.

Could you get a circumstance where the uncertainty in energy is perfectly zero perhaps? Then it may be possible to claim a circumstance zero energy is possible.

Claude.
