We all have to live our lives (in all variants), not in parallel universes (Multiverse), but sequentially (Multichronos).

Googol is a number represented in the decimal number system by one followed by 100 zeros.

Why is mathematics, as E. Wigner noted, so effective in solving physical problems? And why is the world known at all? The answer lies in the complementarity of the observer to the world. We live in a subject-object "correlation matrix", where I - the subject is a correlate. In modern science, there is no understanding of this correlativity, and therefore the fact that the laws of nature work extremely smoothly, to the details of "thought out" mechanisms, is perceived as a miracle.

Our approach to justifying QM allows us to take a fresh look at Everett's interpretation. Recall that Everett's interpretation suggests that the world exists in the form of a superposition of classical realities. In this case, the observer always finds himself in one of them. But in what? After all, the alternatives are equal. The answer to this "unsolvable" question turns out to be quite simple, if we take into account the "anatomy" of quantum superposition. As discussed above, each pure quantum state is formed by a set of intentional states, the transitions between which are carried out in latent time. For example, superposition | ψ 〉 =| ψ 1 〉 +| ψ2 〉_means that the trajectory of the system in the intentional space "sweeps" the states | ψ 1 〉 and | ψ 2 〉 in latent time so that the probability of detecting the system in one state or another during the measurement is proportional to the time spent by the system in these states. Let the system visit the state | ψ 1 〉 , and ξ visited state | ψ 2 〉 . Then the probabilities will be equal to P 1 = ξ 1and P 2 = ξ 2 . They can be found as: P 1 =| ψ 1 | 2 and P 2 =| ψ 2 | 2 . It is important to understand that from the point of view of a possibly non-existent external observer, the components of the superposition are visited sequentially, while from the point of view of an internal observer, they are visited simultaneously.

What physical laws can the subject of the finite world discover by observing it from within? It is shown that the world for such a subject will necessarily be quantum, it will necessarily be relativistic, and it will necessarily be irreversible.
