Our universe is not a true vacuum, it is a false vacuum according to Higgs mass.
This paper claims that the universe was created out of nothing.
But this nothing is really something - "false vacuum"..
Another option is that the universe is, in some sense, in a temporary state and what we think of as reality is what is called a false vacuum.
A false vacuum occurs when a field has two “ground” states, one higher than the other.
You can think of the false vacuum as being like a valley..
The false vacuum decay is of absolutely no concern.
The prediction from the standard model means that in every practical sense there is no chance of this happening.
The cosmos is a long lived beast..
Ultimately, a perfect vacuum isn't possible because quantum theory dictates that energy fluctuations known as 'virtual particles' are constantly popping in and out of existence, even in 'empty' space.

The Higgs potential determines whether the Universe is in one of two states: a true vacuum, or a false vacuum.
A true vacuum is the stable, lowest-energy state, like sitting still on a valley floor.
A false vacuum is like being nestled in a divot in the valley wall – a little push could easily send you tumbling.Sep 14, 2015.
A false vacuum is an idea from theoretical physics: In quantum field theory, such a vacuum might exist for a very long time, before it changes its state.
Much like with a true vacuum, a false vacuum exists where the energy is minimal.
In the case of a true vacuum, this is at a global minimum of the energy function..
In quantum field theory, the vacuum of space is not truly empty, but there are short-lived photons and particles that pop into and out of existence at the quantum level.
So a vacuum under quantum mechanics is a state with the lowest possible energy, which is some positive value..
We study the nonequilibrium dynamics of the false vacuum in a quantum Ising chain and in an XXZ ladder.
The false vacuum is the metastable state that arises in the ferromagnetic phase of the model when the symmetry is explicitly broken by a longitudinal field.
This state decays through the formation of “bubbles” of true vacuum.
The purpose of this Letter is to show that the false vacuum decay is accessible to current optical experiments as quantum analog simulators of spin chains with confinement of the elementary excitations, which mimic the high energy phenomenology but in one spatial dimension.
This type of vacuum state is called a "false vacuum".
If our universe is in a false vacuum state rather than a true vacuum state, then the decay from the less stable false vacuum to the more stable true vacuum (called false vacuum decay) could have dramatic consequences.
A scalar field φ (which represents physical position) in a false vacuum.
The energy E is higher in the false vacuum than that in the true vacuum or ground state, but there is a barrier preventing the field from classically rolling down to the true vacuum.
