The universe is not symmetric.

"The Standard Model particles and their (hypothetical) supersymmetric counterparts. This spectrum of particles is an inevitable consequence of unifying the four fundamental forces in the context of string theory, but if string theory and supersymmetry are not relevant for our Universe, this picture will serve as a mathematical curiosity only." (BigThink, The Universe is not symmetric)

The universe is not symmetric. Things like galaxies, black holes, and other gravity centers pull the plasma that forms the universe into a form that looks a little bit like an amoeba. 

The galaxy clusters can make potholes in the Universe's outer shell. That makes it look a little bit like the golf ball or some circular saw blades if the universe's geometry is not the ball. 

There are two geometric shapes in the universe. The local and global geometry. The local geometry might seem to be the ball. But the global geometry might be like the galaxy. 

The ball that we see as the universe could be only part of the structure. Outside that ball can be the structure that looks like the DVD plate. One of the reasons, why we cannot see that material disk is that the shine of the galaxies covers that lower energy material disk under it. 

This is one of the reasons why the multiverse is very hard to prove. If we think. That is in the ball-shaped part of the universe. The Higgs Field is the base energy level. 

"The local geometry of the universe is determined by whether the density parameter Ω is greater than, less than, or equal to 1. From top to bottom: a spherical universe with Ω > 1, a hyperbolic universe with Ω < 1, and a flat universe with Ω = 1. These depictions of two-dimensional surfaces are merely easily visualizable analogs to the 3-dimensional structure of (local) space." (Wikipedia, Shape of the universe)

If Ω = 1, the universe is flat.

If Ω > 1, there is positive curvature.

If Ω < 1, there is negative curvature

(Wikipedia, Shape of the universe)

Only if Ω > 1 or the universe is spherical the reborn of the universe can happen. In that case, the material drops into the middle of the universe. And that should make the reborn of the universe possible. When that ultimate black hole goes into absolute vacuum, it should detonate. 

The hypothetical material disk around the ball-shaped center has a lower energy level than the Higgs Field. And then the energy level of the fields outside the universe is even lower than this material disk's energy level. In that case, the energy that comes from other hypothetical universes should travel over at least two main energy barriers.

Then that energy or radiation must travel across the energy barrier that surrounds the galactic cluster, the Milky Way, and finally the Sun. That energy barrier series means that proving the other universe's existence requires that those other hypothetical universes will be at a very high energy level. 

There is a possibility, that four fundamental interactions (Gravity, electromagetism, weak interaction, strong interaction) separated after the Big Bang a little bit different distances from that point. "The idea of unification holds that all three of the Standard Model forces, and perhaps even gravity at higher energies, are unified together in a single framework. This idea, although it remains popular and mathematically compelling, does not have any direct evidence in support of its relevance to reality." (BigThink, The Universe is not symmetric)

The idea of the Grand Unified Theory, GUT is this. All four fundamental forces have different wavelengths. The black hole or extremely powerful gravitation or energy wave can press those four fundamental interactions together. In that model, all four fundamental interactions are pressed into one common wavelength. That wavelength unites the four fundamental interactions. 

The disturbance in the shape of the universe's local geometries causes problems with calculations. If we think that we are in the middle of the quantum field, or Higgs field, which is the base energy field in the universe, we can say that things like black holes and other kinds of things can cause asymmetry in that field. The black hole should pull Higgs Field inside it. 

And that thing causes movements in that field. When black holes and other things pull and move that field. That causes stronger and weaker waves in that field. When a black hole pulls the field inside it. That means. There is less field left. If the energy field is gas or water, we could say. That there are points in that field with lower density. That means there are so-called false vacuums in that field. 

Those false vacuums or lower energy points in the energy field make it possible that the waves and fields are moving. When the Big Bang event happened, we can say that this event were multiple cases where energy fields started to travel out from a certain point. If there was a point that created the lower energy point. That caused the situation there energy started to make whirls around that point. 

The small lower energy points make the waves. And then those crossing waves make the asymmetry. When we think about the shape of the Big Bang there could be some kind of hole in the absolutely straight and stable energy field. When that energy pothole turns deep enough it causes collapse. That collapse formed the energy tower that also collapsed. 

The situation is similar to cases. In which somebody throws a stone in the water. 

That stone transfers energy to water and pushes the hole into the water. And when that hole fills. That causes the form of the water statue. That water statue falls. Causing the wave movement. Maybe the Big Bang event. Or, its beginning is the fallen energy pothole in the energy field. The question is where did that pothole come from? 

If we follow the form of the black hole models there is the possibility that the pothole formed the bubble or vacuumed the static energy field. When that bubble collapses that can cause the wave movement that travels around that place. The vacuum that collapses collects energy at one point. That thing can cause the reflection effect there that packed energy escapes from that point.
