(Updated) Catalog: Physics and Mathematical Problems Solved by the Canvas Model

The Canvas Model, together with Canvas Temporal Mathematics (CTM), resolves, dissolves, solves, derives, or explains over 140 long-standing problems in physics, cosmology, quantum mechanics, thermodynamics, set theory, and epistemology. This paper compiles these problems in a single table, documenting each problem, the decade it was first identified, how many years it remained open, and the Canvas Model's status.

What this catalog contains:

· A comprehensive table of 143 problems spanning centuries of physics and mathematics. Problems include the Measurement Problem (1920s, 100+ years open), the Cosmological Constant Problem (1920s, 100+ years open), the Hierarchy Problem (1970s, 50+ years open), the Strong CP Problem (1970s, 50+ years open), the Singularity Problem (1960s, 60+ years open), the Black Hole Information Paradox (1970s, 50+ years open), the Origin of the Born Rule (1920s, 100+ years open), the Flatness Problem (1970s, 50+ years open), the Arrow of Time Problem (1880s, 140+ years open), the Hubble Tension (1990s, 25+ years open), the Fine-Structure Constant Problem (1910s, 100+ years open), and many more.
· Problems from set theory and foundations of mathematics: The Infinity Problem (actual infinity impossible, antiquity, 2300+ years open), Set Theory Paradox Problems (Russell, etc., 1900s, 120+ years open), the Continuum Hypothesis Problem (1870s, 150+ years open), the Axiom of Choice Problem (1900s, 120+ years open), Gödel Incompleteness (1930s, 90+ years open), and the Turing Halting Problem (1930s, 90+ years open)—all dissolved or explained within the framework.
· Problems from quantum foundations: The EPR Paradox (1930s, 90+ years open), Bell Inequality Violation (1960s, 60+ years open), the Quantum Zeno Effect (1970s, 50+ years open), the Casimir Effect (1940s, 80+ years open), the Unruh Effect (1970s, 50+ years open), the Aharonov-Bohm Effect (1950s, 70+ years open), the Hardy Paradox (1990s, 30+ years open), the GHZ Paradox (1980s, 40+ years open), the Quantum Eraser (1980s, 40+ years open), the Delayed Choice Quantum Eraser (1990s, 30+ years open), and the Two-Slit Problem (1920s, 100+ years open)—all resolved, derived, or explained.
· Problems from thermodynamics: The Gibbs Paradox (1870s, 150+ years open), the Loschmidt Paradox (1870s, 150+ years open), the Maxwell Demon Paradox (1860s, 160+ years open), the Ultraviolet Catastrophe (1900, 120+ years open), and the Vacuum Catastrophe (1920s, 100+ years open)—all resolved, explained, or dissolved.
· Problems from cosmology: The Horizon Problem (1970s, 50+ years open), the Monopole Problem (1970s, 50+ years open), the Curvature Problem (1970s, 50+ years open), the Initial Singularity Problem (1920s, 100+ years open), the Coincidence Problem (1990s, 30+ years open), the Why Now Problem (1990s, 30+ years open), the Boltzmann Brain Problem (1890s, 130+ years open), the Fermi Paradox (1950s, 70+ years open), and the Fine-Tuning Problem (1970s, 50+ years open)—all solved, resolved, or explained.
· Problems from the Canvas Model itself: Novel predictions derived from first principles, including the \pi/2 waveform asymmetry, the first harmonic phase shift, the second harmonic suppression, the spectral gap of the prime lattice (\lambda_1 \geq 1/8), the Cheeger constant of the prime lattice (h = 1/2), the critical exponent for three-body escape (\nu = 1/2), the Lyapunov exponent scaling (\lambda \propto \sqrt{e - e_c}), the tensor-to-scalar ratio (r \ll 0.01), the CMB spectral index running (\alpha_s \approx -6.6 \times 10^{-4}), the dark energy equation of state (w + 1 \sim 10^{-2}), the time variation of \alpha (\dot{\alpha}/\alpha \sim 10^{-17} yr^{-1}), black hole remnant mass (M_{\text{rem}} \approx M_P), primordial black hole formation fraction (\beta \sim 0.085), and the prediction that a fourth generation of fermions does not exist.

Status definitions:

· Solved: The problem has a definite, quantitative solution within the framework.
· Resolved: A long-standing paradox is removed; the physics is clarified.
· Dissolved: The problem disappears because its assumptions are incompatible with the framework.
· Derived: The phenomenon is derived from first principles with no free parameters.
· Explained: A clear mechanism is provided.
· Predicted: The framework makes a novel, testable prediction not previously recognized as a problem.

Why this matters:

The Canvas Model does not merely describe these phenomena—it explains why they are the way they are. All entries are derived from the eight primitives and four core equations of the Canvas Model, with zero free parameters. This compilation demonstrates the unprecedented scope and explanatory power of the framework. It is a living document; updates will be published as new problems are solved and as experimental confirmations are obtained.
