How TGD avoids the catastrophe caused by observe-free Universe?

Gary Ehlenberger sent a link to a very intersting Quanta Magazine article titled “Cosmic Paradox Reveals the Awful Consequence of an Observer-Free Universe”. The two first paragraphs of the article give a good view of the problem.

But when a group of researchers examined a universe intriguingly like our own in 2019, they found a paradox: The theoretical universe seemed to admit only a single possible state. It appeared so simple that its contents could be described without conveying even a single bit of data, not even a choice of a zero or a one. This result clashed with the fact that this type of universe should be capable of hosting black holes, stars, planets — and people. Yet all those rich details were nowhere to be seen.

To me this result is not terribly surprising. The paradox of heat death is a well-known intuitive way to state the problem. The outcome is the final catastrophe putting an end to the materialistic view. The catastrophe is also due to the sticking to too simple mathematics based on real numbers which have no internal anatomy, in accordance with materialism in which only magnitude matters. Universe is much much more complex. AdS/CFT brings in strings and extended particles but is not a realistic solution.

1. One part of the problem is the completely wrong view of space-time as a single smooth manifold such as AdS. In TGD, space-time is a union of an arbitrarily large number of 4-D Bohr orbits of 3-surfaces in H=M⁴×CP₂ obeying holography, which is almost deterministic: this is absolutely crucial for having fermion interactions for formally free fermions.

Intersections of space-time surfaces as 2-D string world sheets give rise to the geometric aspect of interactions. H=M⁴×CP₂ explains symmetries and fields of the standard model and is mathematically the only possible choice: number theory-geometry duality at the level of physics and the existence of the twistor lift dictates this choice. The dynamics reduces to that of space-time surfaces. By general coordinate invariance, there are only four local degrees of freedom.

Classical number fields, reals, complex numbers, quaternions, octonions emerge as an essential part of dynamics via M⁸-H duality (see this). p-Adic number fields appear also and the corresponding functional fields appear too.

Space-time surfaces represent numbers in both the classical sense and as elements of function fields see (this, this, this).
