Between a circle and a square lies the smallest gap geometry allows — and perhaps the deepest one physics has yet to understand.

Dedicated to François Viète (1540–1603),

whose nested radicals revealed the infinite geometry

between the circle and the square,

and in doing so, hinted at the balance of opposites that underlies all creation.

Time has no beginning or end, there is only an in between.

This site proposes a quantum-geometric foundation for existence: a minimal construction in which linear extension and rotational curvature meet at a symmetry-locked midpoint, and the large-scale behaviour of the cosmos emerges as a time-symmetric cycle of expansion and renewal. In this model, geometry is not merely the stage for physics—it is the generator of its constraints: quantization, horizons, and the apparent “dark sector” arise as geometric bookkeeping across a conserved, cyclic totality.

Key Equations

A small set of definitions and dynamical postulates anchor the framework. These are presented here as orientation; derivations and context are developed in the full paper.

Seed asymmetry

At emergence, an asymmetric geometric seed,

\[ \alpha \equiv 1-\frac{\pi}{4}, \]

fixes boundary data for the initial partition of the cosmic energy budget within a cube–circle construct. This non-zero geometric residue encodes a primordial imbalance between linear and rotational measures. In the framework developed here, that imbalance induces a controlled loss of global coherence in the pre-emergent state, marking the transition into the dynamically unfolding Big Bang epoch. The expansion phase is thus interpreted not as creation ex nihilo, but as the geometric release of a constrained asymmetry.


Logistic branch evolution

We postulate a logistic evolution on the physical branch-epoch \(t\in[0,L]\),

\[ f(t)=\frac{1}{1+\exp\!\big(-\kappa\,[t-\gamma]\big)}, \qquad t\in[0,L], \]

where \(\kappa\) sets the steepness and \(\gamma\) is the midpoint time. In this framework, \(f(t)\) governs the gradual transfer of energy density from dark energy to dark matter over the course of cosmic evolution on the physical branch. The logistic form enforces a smooth, bounded, and monotonic conversion between the two dark components.

The midpoint \(\gamma\) is fixed by dark–sector equality, defined by \[ \Omega_{\rm de}(\gamma)=\Omega_{\rm dm}(\gamma), \] so that the epoch of equal fractional densities coincides with the inflection point of the conversion curve.

On the dual (time-reflected) branch, the process reverses: dark matter reconverts into dark energy according to the same logistic law under time inversion \(t \mapsto L-t\). The two branches together preserve global symmetry across the full cyclic interval.


Viète-inspired residual factor

The baryonic weight is fixed at emergence by \(\Omega_b=\pi/64\). To encode a percent-level residual associated with bidirectional circle–square closure, we introduce the dimensionless Viète-inspired factor

\[ \beta_{\mathrm V} \equiv \frac{9\sqrt{2}}{4\pi}\simeq 1.01286, \]

which parametrizes a small geometric imbalance between dual curvature projections.


Viète’s product and curvature refinement

Viète’s formula,

\[ \frac{2}{\pi} = \prod_{n=1}^{\infty} \cos\!\left(\frac{\pi}{2^{\,n+1}}\right), \]

arises from repeated half–angle refinement of inscribed regular polygons. Each cosine factor may be interpreted as a discrete curvature–projection step that incrementally reduces the discrepancy between polygonal and circular geometry.

Within the present framework, this infinite product serves as a geometric archetype for stepwise asymmetry accumulation. Just as each refinement introduces a controlled correction toward circular closure, baryogenesis may be viewed as a cumulative, computational process in which successive microscopic symmetry breakings yield a small but persistent matter excess.

The baryonic fraction therefore emerges not from a single discontinuous event, but from iterative geometric bias encoded in discrete projection steps — a refinement process analogous to Viète’s convergence, where asymmetry is accumulated gradually yet irreversibly across the unfolding epoch.

Quantum Geometric Framework: unit square with diagonals, quarter-circle arcs, and labels showing 1, 1/√2, and π/4.
Quantum Geometric Framework. A unit square (side length = 1) partitioned into four symmetric sectors defined by diagonal radii of 1/√2 and quarter-circle arcs subtending angles of π/4. The construction highlights the intrinsic relationship between √2—the diagonal scaling factor emerging from Euclidean symmetry—and π—the measure governing rotational curvature. Their intersection within a normalized geometric field illustrates how linear extension and circular curvature co-define structure. In this framework, the interplay between √2 and π is proposed as a foundational geometric tension from which spatial coherence, symmetry breaking, and emergent physical order may be understood.
Logistic evolution of the dark-sector composition shown versus equality-centered time t_eq.
Logistic Evolution of the Cosmos. Logistic evolution of the dark-sector composition, shown as a function of the equality-centered time coordinate \(t_{\rm eq}=t-\gamma\) so that dark-sector equality occurs at \(t_{\rm eq}=0\). The mirror-closed physical branch-epoch corresponds to \(t_{\rm eq}\in[-\gamma,+\gamma]\), i.e. from emergence (\(t=0\Rightarrow t_{\rm eq}=-\gamma\)) to the mirror endpoint (\(t=2\gamma\Rightarrow t_{\rm eq}=+\gamma\)). Values outside this interval represent analytic continuation/bookkeeping rather than an extension of a single classical branch.

“What, if some day or night a demon were to steal after you into your loneliest loneliness and say to you: ‘This life as you now live it and have lived it, you will have to live once more and innumerable times more’ ... Would you not throw yourself down and gnash your teeth and curse the demon who spoke thus? Or have you once experienced a tremendous moment when you would have answered him: ‘You are a god and never have I heard anything more divine.’”
