I believe the Nature article on the universe being created from a vacuum
fluctuation relates to the Heisenburg principle. An energy fluctuation is
allowed if the time is short, ie Delta E times Delta t < h. [Or is it more
strictly h/2 pi ??!, it has been a long time since QM class !]. Guth et al
argue that the temporary energy fluctuation was then caught in a false vacuum
and stabilized so it could not revert back to zero.
Further, in the early days of thermodynamics it was postulated that the energy
of the universe is a constant. And thermo teaches that only changes in energy
can be measured, so an arbitrary reference state can be chosen, so that
constant is zero, or any other quantity for that matter.
