Can the universe decay?

"A false vacuum is at a local minimum of the energy state (right). Its energy is higher than that of the true vacuum (left)."  (Simple Wikipedia, False vacuum) 

When a reality collapses like a cardhouse, that event makes room for the new reality. There is a possibility that the universe decays through false vacuum decay. The idea is that the universe is a more high-energy area than the space around it. 

This is why energy leaves the universe. If that process happens too fast. That decreases the universe's energy level. That increases the material vaporization or turns particles into wave movement very fast. The universe may fall from its energy state and reach a more stable state. The idea is that when the energy level rises compared to the environment. Particles or systems become unstable. 

When the differences between energy levels in the material and its environment rise. The speed of energy flow from the material rises. 

And things like gravitation disturb that wave movement's symmetry. 

That thing can make the energy asymmetries in wave movement. 

The particles are released when the temperature or energy level in the universe decreases. 

In some models, the universe can even decay. In that case, the universe has polarity. 

That polarity pulls material into the universe's "poles". 

And that can make two giant plasma clouds on two sides of the universe. 

That means those. Hypothetical but possible plasma clouds. Will pull the universe into two parts.  Both sides of the universe form two energy potholes. In that hypothetical process. 

There may be so-called energy hills between those potholes. And that makes energy impossible to travel between those potholes. That causes the false-vacuum decay. 

Things like false vacuums or cosmic voids can have their plasma rings.

That plasma is like a wall that doesn't let particles fill the false vacuum. If that shock wave does not exist. Maybe particle and energy flow fill a false vacuum like it fills the real vacuum. If a false vacuum surrounds the particle is invisible. 

The outcoming energy keeps that wave in its place and that stabilizes the false vacuum. Sometimes false vacuum is called a "false black hole". The false vacuum is like a step at the energy slope. 

"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. With a false vacuum, the energy function is only at a local minimum. As is illustrated in the figure, there is a "peak" between the local minimum and the global minimum of the energy function." (Simple Wikipedia, False vacuum) 

"A false vacuum is at a local minimum of the energy state. Its energy is higher than that of the true vacuum" (Simple Wikipedia, False vacuum) 

The false vacuum can be like like a table at the edge of cosmic voids. That means the universe can involve multiple false vacuums. 

The idea is that the false vacuum has a lower energy state than "regular space" has. But its energy state is higher than a true vacuum. 

When we think about reality and black holes we can think of the 2D models. That black holes pull quantum fields into a flat state.

We can think that the universe is like a card around black holes. 

Then we must turn those cards into the position that they form the 3D-ball-shaped entirety.

The flat space will form the ball-shaped spacetime forms a ball that consists of multiple 2D layers in the ball-shaped structure. That means the black hole presses the 3D reality into multiple 2D layers. That surrounds its event horizon. Those pressed dimensions or energy fields are denser models of the 3D spacetime where we live. The difference is that the 2D space from the structure looks like pieces of paper are horizontally around the black hole. 

When the universe releases its energy. It turns more stable. Because energy flow turns slower. 

The problem is that the radiation that leaves from the most out layer of the universe pulls more radiation to fill its place. That causes a chain reaction their energy level falls in the entire universe.
