Does the end of the universe begin?

   

 Does the end of the universe begin? 

Is the final era of the universe began? The fact is that we must determine the final era of the universe. Before, we can answer that question. What is the length of the final era or final sequence? We can say that the entire existence is to wait for the end. But can we say that the final era begins from the birth or the point where the observer stands? Is the final era only the era that is left and forward to us? Or did the final era of the universe begin just after the Big Bang? 

The fact is that the universe is going to its ultimate fate. The road to ultimate fate began when the Big Bang released material to space. After that, the universe is going to its ultimate fate. In the same way, we can think. That when humans borns the road is to the grave. The universe is one of the most interesting things. And there are two ways how the universe will face its fate.

If the universe is a ball or spherical it's closed. The ultimate fate of the closed universe is a big crunch when the entire material drops to the black hole. There are two other possibilities for the shape of the universe. Those two other shapes are open universes. And that means the ultimate fate of the universe is a big silence or big freeze where the particles turn to wave movement and the universe will just vanish after it will enlarge enough. In open universes, gravitation cannot stop the expansion. And that means the universe will just vanish. 

The Big Bang theory will support the theory of the ball-shaped universe. There is the possibility that the Big Bang would throw the material into the form of time class like some supernovas are made. But there is the possibility. That between hyperbolic structures is a large mass of dark matter. That is making the universe a spherical structure. The problem is to determine the shape of the universe. At least 85% of the universe is formed of dark matter that is invisible to us. So we don't know the real shape of the universe. 

In this text, I use the name "modern universe" for the universe where we live. The young universe might seem the same as our universe. But that young universe was very different than the modern universe. 

It was smaller, higher energetic. And the material was a little bit different than in our universe. The energy level was higher and the weight of individual particles in the young universe was higher than it's now. 

When the Big Bang released material to the space that thing was also released "visible energy". Visible energy means the wave movement that interacts with visible material. Dark energy means wave movement that doesn't interact with visible material. The origin of dark energy is suspected the dark matter particles. Dark matter is the name of the mysterious gravitation effect in the universe. 

The dark matter is predicted to be similar material with the visible material. But the size of the particles of dark matter is different from the size of particles of visible material. That means the wave movement that origin is in dark matter is invisible to us. That is the most believable explanation for dark energy. 

Dark energy means mysterious wave movement. That expands the universe. So the dark matter would send the wave movement that is invisible and unable to capture. 

All energy in the universe. Also released in the Big Bang. That means there is no place where the universe gets more energy. And the expansion of the universe causes. That the energy density or energy layer in the universe is decreasing. 

When the size of the universe grows the energy must fill bigger space. And that causes the universe is losing its energy. The reason for expansion is that the space outside the universe has a lower energy level than the universe. And that causes the energy to flow outside the universe.

There is nothing that can replace that energy. And that means the universe will turn so large that there can not form new stars. The pressure of quantum fields will decrease. And thermal energy will rip galaxies in pieces. Because there is only thin gas in the universe that thing causes that the new stars will not be forming. 

When the distance between atoms increases high enough the protons and neutrons will be destroyed. And finally, electrons will turn to wave movement. The thing is that. Even the ultimate fate of the universe would be the big crush. There is a moment when the stars would not form anymore. 

The expansion of the universe began just after the Big Bang. And it continues today. The expansion speed of the universe is the so-called Hubble constant. But when we are trying to compare the modern universe with the young universe. We are facing one thing. 

In the young, hot, and thick universe the speed of light inside the young universe was lower than it's in the modern universe. The reflection, scattering, and more powerful quantum fields caused that photons travel slower than they are traveling in our universe. The speed of light was cosmic speed limit but it was lower than in our universe. 

Same way time moved slower in the young universe than in the modern universe. The higher energy level meant that the particles in the young universe were higher energetic than in the universe. There is suspicion that the  Big Bang was the white hole. That theory has formed one of the most interesting and incredible theories of the ultimate end of the universe. 

In that theory, the universe would collapse into a black hole. Because time moves backward inside the event horizon that black hole would take the material to the point where it was formed. 

Time dilation means when escaping velocity is the same as the speed of light time stops. And when escaping velocity turns higher than the speed of light time moves backward.  

So if the ultimate fate of the universe is the big crunch. The material travels to the point where the black hole was born. The same thing happens when the entire universe falls into the black hole. And that theory is called as Phoenix theory. That means the universe is reborn again and again. 

But when the material would travel through the black hole it would not be the same material again. The size of the particles would be different. And the new universe would be reborn as the mirror universe to the original universe.
