I have good idea brief explanation about universe balance requirement needs 7#(We are living in) vacuum universe, 6#Fluidic universe, 5#Filaments universe, 4#anti universe, 3#Observable universe, 2#Parallel universe, 1#Fabric universe, Entropy universe, opposite anti-mirror universe, Multiverse universe.
Example: Fluidic universe is a realm located in another dimension, consisting entirely of matter in a fluid state, rather than a vacuum, and accessible only through the creation of an interdimensional rift using quantum singularities. The fluidic realm has no stars or planets
Other example: Filaments universe is nova heat, which human cannot survivor this.
Parallel universe most extreme dangerous in entire universe, they may look like us and they has set each path life.
anti universe are opposite side.
If only one Vacuum universe then entire other universe would thrown spin out balance even kill whole everything universe in become death (white universe with black deadly star) even worse than parallel universe does.
Well, what you think and post here to discuss about theory Multiverse. I not know if someone posted thread already or not, I not sure about that, Enjoy discussing.
