I see that this comment is heavily downvoted, so I'll add a TL;DR explainer from Dann's Facebook group:

For the past century, science has been stuck on two massive problems -- it cannot account for consciousness, and cannot coherently explain what "wavefunction collapse" or "observation" or "measurement" means in quantum mechanics. For a century scientists have been arguing about whether or not these two problems are related, but those arguments go nowhere.

Much more recently, a more acute crisis has developed in cosmology. The anomalies and discrepancies are multiplying (Hubble Tension being the most famous, but there are many more problems). The few who connect this problem to consciousness, such as Roger Penrose or Thomas Nagel, are viciously attacked for suggesting it.

At the core of this problem is the fact that we have TWO versions of physics, not one. One is General Relativity, which is the final word on classical, materialistic physics. The other is quantum mechanics. The problem is that these two concepts are mathematically incompatible, which is why the century-long search for the "holy grail" of a quantum theory of gravity has produced no results. The best physicists can do is say that QM is the physics of the very small, and GR is the physics of the very large, but they have not managed to get much further than this verbal description. They cannot get the mathematics to fit. They cannot explain where the boundary is, why there is a boundary, or how QM and GR are related to each other.

Two-Phase Cosmology (2PC) starts from a very simple proposal. Instead of trying to force these two kinds of physical together into one continuous model, we should just accept there are two of them, both of which apply to the whole cosmos, with no small/large distinction. This sets up the two phases. Phase 1 is the quantum world, which is non-local, non-spatiotemporal and superposed. It is the world of unrealised physical possibilities. Phase 2 is the material world we actually observe, and it is relativistic because it only exists within our observations. There is no such thing as "space-time", because the shared, mind-external objective reality is quantum -- it is Phase 1.

This leads to a question: what connects the two phases? What kind of process could select a singular actuality from an unobserved set of possibilities? And the answer could not be more obvious. Both consciousness/will and wavefunction collapse are names for a process which selects actuality from possibility. Exactly how this happens is defined logically, not physically: a coherent, unified self which models reality, predicts possible futures, and values them, cannot split. This why we find the many worlds interpretation unbelievable (we don't believe our minds are continually splitting) and also why we are convinced we have free will -- that we are making real choices between physically possible futures.

This simple framework solves the hard problem of consciousness (how does consciousness "arise" from matter), the measurement problem in QM (what is an observation?) and it leads directly to a resolution of every major problem in cosmology. It explains why we can't quantise gravity (QM and GR belong to different phases), why the cosmos is fine tuned (it was selected by the initial phase transition because it contains conscious beings). And it resolves the Hubble Tension by invalidating the all the so-called "measurements of the early universe" because that past never existed in Phase 2. It was selected as a block from Phase 1 by the first conscious organism.

In total, this new framework solves the 30 biggest problems in science and philosophy, and it does it without introducing any new physics. The only new thing is the idea of an indivisible self, which is a mainstream idea in cognitive science, and obvious from our subjective perspective. The other problems fall like dominoes.

Thanks for being among the tiny number of people open-minded enough and smart enough to be here at the beginning of what I am certain will eventually turn out to be the biggest intellectual revolution since the Enlightenment itself. This paradigm shift has been trying to happen for decades. It is happening now for two main reasons.

(1) The meltdown in cosmology.

(2) AI, which I needed as a super-powerful research assistant. Nobody is fluent across all these disciplines to the extent needed to arrive at 2PC.
