Paper D has just passed 100 views! It develops a deterministic, geometric account of quantum measurement: outcomes emerge from partitions of a single continuous surface Σ, not from collapse or parallel worlds. https://t.co/TvQlv7dSRc

Paper B just received a very positive expert review on Qeios. The reviewer highlighted the clarity of the argument and the novelty of deriving Born weights from symmetry, while also suggesting useful improvements for the next revision. Read it here:

As judged from the introduction, the author may not seem to be aware that there are many other derivations of the Born rule from physical principles. Some examples are Caves et al. (2002) Physical...

QBism treats quantum states as personal beliefs and makes probabilities subjective. It gives no clear account of what the world is doing. CSD is realist. Outcomes come from objective geometric isolation, not beliefs. A physical story for measurement: https://t.co/Dwnwn2Hi7o

Quantum physics feels strange because we normally see the “averaged-out” world, not the microscopic rules. At small scales you see interference and superposition; at large scales, constant interaction washes them out and things look classical. #qm https://t.co/ZoNywntcpy

@grok is this framework proposed in this paper and thread valid?

CSD does not attempt to replace quantum mechanics; instead, it shows how its statistical rules can emerge from conserved geometry beneath the standard formalism.

The framework is deterministic, testable, and compatible with constraints such as Bell, Kochen–Specker, Fine, and PBR through its context-dependent partitions.

CSD preserves the full mathematical structure of geometric quantum mechanics but adds a clear physical interpretation without invoking many-worlds, hidden wavefields, or collapse postulates.

Interference visibility depends on how isolated the system is: strong environmental coupling reduces overlap between regions, suppressing interference exactly as experiments observe.

This makes quantum statistics a geometric property, not an added probabilistic rule.

Long-run frequencies follow invariant geometric volumes, not intrinsic randomness: the ratio μ(Ωᵢ)/μ(Ω₀) numerically matches |ψ|² because the underlying symmetry fixes the unique invariant measure.

When a system interacts with an apparatus or environment, the geometry of Σ naturally splits into well-separated regions Ωᵢ corresponding to macroscopic outcomes.

The usual wavefunction ψ is interpreted as epistemic information that summarises what an observer knows about which region of Σ the system might occupy.

A system always occupies one definite microstate x(t) on this surface, so measurement outcomes reflect where that point lies rather than any collapse of a wavefunction.

Constraint-Surface Dynamics (CSD) proposes that quantum behaviour arises from deterministic motion on a finite geometric surface Σ equipped with a volume-preserving flow. The full ontological picture is developed in Paper D: https://t.co/ZoNywntcpy
