Have I forgotten anything? All right, I recovered pretty quickly, it's time to continue. Oh, shit! I forgot about the fact that BBT only applies to this and the previous Universe! All the iterations that the Observer experienced before them were characterized by immutability. I have to strain again...
— Although you copied the knowledge of the Big Bang Theory, but it only tells about the origin of my Universe, but it also corresponds to this one. No, that's not it... Hurts... Okay, now I'll explain everything in order! At first...
----------------------------------------
Before this Universe, there were an unimaginable number of identical alternating Universes. The Observer stopped counting after the googolquadroplexth (10^10^10^10^10^100th). But what about the primordial one?
When the primordial Universe emerged from the singular point state, this process occurred not in 5.39116(13)x10^(-44) seconds, as according to BBT, but slightly faster. This difference in the duration of the Planck epoch — the transition from the singularity to the birth of the Universe — is impossible to calculate, but even it has a value that will be discussed later. So, what happened?
Except for the difference in Planck time, everything went in the order of BBT. First, the separation of gravitational radiation from matter. Next: the first phase transition — Cosmic inflation (expansion), at the end of which, the quark-gluon plasma began to cool. The second phase transition is bariogenesis (the formation of protons and neutrons) from the cooled plasma. Further cooling and the third phase transition — the formation of physical forces and elementary particles. After the recombination of protons with electrons, the matter of the Universe became transparent, available for observation in electromagnetic radiation. And dark energy, which is impossible to see because it interacts with matter only by gravity, causes the Universe to constantly expand with acceleration.
All of the above was followed by the usual formation of space objects: nebulae, stars, planets, and all that.
But life never formed, and where this planet is now, there was one of the largest voids (an empty space between clusters of matter).
Naturally, the Observer observed this Universe, absorbing knowledge, doing nothing else...
...Up to a certain point.
Heat death, or Big Freeze, is the final state of the Universe as a closed thermodynamic system, with maximum entropy (irreversible energy dissipation) due to excessive expansion. How does this process work?

The beauty of cosmos has faded. The cosmos has died.
Was that inevitable?
Was that the answer to the Observer's question: «Exodus of what?»?
Was that how everything was supposed to end?
Was. Maybe was. And no, it was only beginning!
Even the constant expansion froze after a Big Freeze. The primordial Universe became like a frozen bubble. The Observer went beyond its boundaries and was dumbfounded (Yes, he was!). Void Decay was turning the primordial Universe into Nothing. The rate of Void Decay was equal to the finite rate of expansion. Moreover, it accelerated in the same way. Soon, not a trace of the primordial Universe remained. It is somewhat similar to vacuum decay, but it was not a true vacuum, but a complete absence of Everything.
The Observer remembered everything. He had not forgotten neither his purposes nor his desires, but what else could he do? Only wait.
And he was not waiting long.
Start of the cycle.
Point.
Bang.
Birth.
Expansion.
Cooling.
Matter.
Existing.
Death.
Decay.
End of the cycle.
The inevitability. The immutability. The cyclicity. Again and again, everything was repeated. From the smallest quark to the largest star, there were no deviations from the previously observed sequence of events. Even the collision and merger of black holes took place in the same way.
For more than googolquadroplex times.
It was then that the Observer doubted his purposes, his desires.
But the Observer never dared to doubt Nobody. He obediently did not make any changes, following His precept.
But he had a dream. The dream is to one day be free from this burden, be free from the inevitability, the immutability, the cyclicity and dread to No-... No. After all, he still feels nothing but a thirst for knowledge...
