Jacobson and Einstein in the Elevator[:] A Thermodynamic View of Gravity Without Geometry

Authors: A. Schubert
Comments: 7 Pages.

We discuss a classical thermodynamic model of gravity that is based on the concept of negative heat capacity. This model requires no curvature, no quantum fields, and no microscopic assumptions. It complements Jacobson’s thermodynamic derivation and Verlinde’s entropic gravity.

By treating a freely falling system as an entropically active object, we show that gravitational acceleration emerges as a macroscopic entropy gradient, induced by internal heating and driven by energy loss. Using a temperature field T(R) = GM/(kB R) and a logarithmic entropy function S(R), we recover Newton’s inverse-square law as a purely thermodynamic effect:
F = T(R) ⋅ dS/dR = -GMm/R2.

Placing this result into a broader framework, we propose that both gravity and quantum measurement reflect a deeper thermodynamic structure: the global tendency of the universe toward a normal (Gaussian) entropy distribution. While spacetime geometry expands toward equilibrium (dS → 0), localized quantum information follows the opposite direction — toward entropy increase (dS → 1).

Gravitation, motion, and measurement may thus be unified under a single principle: projection into the thermodynamic structure of a Gaussian universe.

A Covariant Quantum-Geometric Model for Dark Energy: The UCM-Neo-GCV Proposal

Authors: Bautista Baron
Comments: 7 Pages.

We propose a covariant quantum-geometric mechanism for dark energy, where the vacuum energy density ρq = σH4+QH emerges from conformal anomalies and dissipative effects in curved spacetime. The UCM-Neo-GCV model introduces no new dynamical fields, preserves gravitational wave speed (cg = c), and predicts an intermediate Hubble constant (H0 ≈ 69.2 ± 0.8 km/s/Mpc)—bridging the Planck-SH0ES tension. A novel geometric screening mechanism ξeff(ρ) ensures General Relativity (GR) is recovered in high-density regimes, while the σH4 term may explain JWST-observed early galaxy formation at high redshifts. The model yields a dynamic equation of state wq(z), falsifiable with Euclid, DESI, and LISA, and aligns with quantum field theory in curved spacetime, offering aminimalist alternative to ΛCDM, quintessence, and modified gravity theories.

Fractal Physis: Structural Decoherence and the Cosmological Basis of Wavefunction Collapse

Authors: Danny Westwood
Comments: 4 Pages.

We propose a novel structural model of quantum decoherence based on the fractal coherence properties of the Cosmic Microwave Background (CMB). Using wavelet energy scaling on Planck SMICA data, we extract a scale-dependent coherence function f(l) and map it to physical space f(z) via a logarithmic transformation. This empirical function is integrated into a modified Schr ̈odinger equation, introducing decoherence as a function of cosmological structure.Simulations of double-slit propagation under this framework reveal coherent-to-incoherent transitions that align with real CMB-derived decoherence boundaries near l ∼ 4000. Our results suggest a cosmologically-grounded, scale-structured foundation for quantum-classical transition,offering a testable alternative to environment-based interpretations of wavefunction collapse.

Nodes of Time — Conformal Noding Cosmology (CNC): An Extension of Conformal Cyclic Cosmology (CCC)

Authors: Christopher David Rice
Comments: 25 Pages. Also submitted to CQG, Manuscript ID: CQG-112842

This paper proposes Conformal Noding Cosmology (CNC), a speculative yet physically motivated extension of Roger Penrose’s Conformal Cyclic Cosmology (CCC). Unlike CCC’s requirement for a global conformal transformation at the end of an aeon, CNC posits that causally isolated, thermodynamically silent regions in an expanding ΛCDM universe may undergo conformal rescaling independently—giving rise to what are termed "Nodes of Time." These regions emerge not from high-energy events, quantum fluctuations, or tunneling, but from expansion-induced causal disconnection.We define a new type of observational horizon based on redshift limits, explores the thermodynamic conditions under which a region becomes functionally massless, and derives equations for redshift cutoffs and scale invariance thresholds. CNC introduces a branching, decentralized cosmogenesis model that aligns with GR and conformal geometry without invoking speculative particles.

Thermodynamics of Gravity: Negative Heat Capacity and MOND

Authors: A. Schubert
Comments: 9 Pages.

We explore the thermodynamics of self-gravitating systems with negative heat capacity (C < 0) and develop a classical model for gravitational attraction. Our approach shows that heat flows from colder to hotter regions, reversing typical thermal diffusion. This process generates an entropic force dependent on temperature and the spatial change in entropy. In regions of high acceleration (a >> a0), this force matches Newtonian gravity, proportional to the inverse square of distance. In low-acceleration regions (a << a0, where a0 ≈ 1.2 × 10-10 m/s2), it transitions to an effective acceleration that scales with the square root of the product of classical acceleration and a critical value, aligning with Modified Newtonian Dynamics (MOND) and explaining galactic rotation curves. Unlike models using quantum effects or holography, our derivation relies solely on classical thermodynamics and the self-heating of gravitating systems. This perspective redefines gravity as an emergent outcome of heat concentration, connecting classical physics to astrophysical observations without requiring dark matter.

Nodes of Time - Conformal Noding Cosmology (CNC): An Extension of Conformal Cyclic Cosmology (CCC)

Authors: Christopher David Rice
Comments: 25 Pages.

In standard Conformal Cyclic Cosmology (CCC), the entire universe evolves toward infinite expansion, eventually reaching a conformal scale-invariant state, from which a new aeon emerges. We present a conceptual extension in which causally disconnected, massless regions within the expanding universe independently attain scale invariance, forming "nodes of time". These nodes, bounded by their own cosmic event horizons and devoid of massive particles, become locally conformally invariant and thus capable of being rescaled into new Big Bang-like origins. This multiversal noding process circumvents the need for speculative phenomena such as electron decay or global entropy resets. Instead, each node emerges naturally through geometric isolation, not energetic birth. This perspective reframes cosmic rebirth not as a cyclical global reset but as a branching of causally isolated regions, each born not in a violent singularity, but in the silent disappearance of scale.
