What makes the ultimate fate of the universe interesting?

Today, researchers talk more about the universe's ultimate fate than ever before. One of the things that makes this phenomenon or the case interesting is that there are some kinds of ideas or evidence that there were universes before our universe. 

Sir Roger Penrose and his team reported that some primordial black holes, or their radiation is some kind of anomaly, which tells that those primordial black holes bring information from the universe, that existed before our universe. Proving that thing is very difficult. in a very old universe, what we can call a post-material universe is two or maybe three types of material and energy. 

The energy and wave movement, along with black holes are the types of material and energy. It's possible. That there are also some neutrons in neutron stars, or quark stars in that very low-energy universe. The main particles are neutrinos, electrons, and maybe protons. In the low-energy, cold universe even neutrinos can have a high energy level if we want to compare that situation in the distant future with the situation in today's universe. 

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.

 If Ω > 1 the universe is closed. And that makes the Big Crunch possible. Otherwise, the ultimate fate of the universe is the Big Silence. Or the Big Rip. But when we think of the open universes and especially the flat universe, things like supermassive black holes can form quantum dots or potholes to that layer. 

Those quantum dots can pull the layer together. In a cold and static universe, the black holes interact with each other at longer distances. So, could the gravity of those black holes pull them together anyway and then form the big crunch? 

The universe is more stable than today. And that means the butterfly effect is more powerful than today's universe. The protons or electrons can form the electromagnetic or quantum whirl called "kugelblitz" which is a theoretical black hole formed straight from the wave movement. In a stable universe. The black hole's gravitational effect affects enormous distances. 

If the universe is closed. That causes the Big Crunch. The only known case where the big crunch can be possible is that the universe is spherical. Or maybe when the black holes detonate in the post-material universe those things cause situations where the impacting radiation from those erupting black holes can create a situation. 

Where the universe could be reborn. The idea is that in the hyperbolic and straight universe can be potholes, the quantum dots that can pull the universe together. Those quantum dots would be the supermassive black holes. 

Even if the universe's end would be the Big Silence. The superstrings continue their infinite journey. And that means the universe will never reach the static conditions. Even if those interactions are weak, the universe is so cold and in stable order, which means the smallest possible interactions cause a strong effect. 

And then what does that mean? 

The hypothetical Kardashev scale 7 civilization can be a remnant of hypothetical past universes. 

There is a possibility: that there was a universe before our universe. That means there is the possibility that some hypothetical civilization can survive the Big Crunch. That thing means that the Kardashev scale 7 civilization can be the civilization of the god, and could be a remnant from the universe before this universe. 

In some models, hypothetical hyper-civilization can increase its craft's energy level to so high level. That the material in the craft can exist longer than other materials in the universe. And then that civilization can transfer itself from the past universe to the new universe.
