Photon Touching: A Novel Mechanism for the Emergence of Classical Reality

Grigor Kirakosyan

This preprint introduces the Photon Touching Theory, a new conceptual framework in theoretical physics. The theory proposes that classical reality continuously emerges through a fundamental process called "photon touching" — a topological puncture of space-time occurring in the dark intervals between photons. The framework offers natural explanations for wave-particle duality, quantum entanglement, the origin of quantum foam, and the accelerated expansion of the Universe. It also addresses several major unsolved problems of the Standard Model, including quark confinement, the Higgs hierarchy problem, the nature of virtual particles, and the cosmological constant problem. This work presents a novel perspective on the quantum-to-classical transition and suggests several testable predictions.

Quantum equivalence, the second law and emergent gravity

Dries Sels, Michiel Wouters

Since the advent of quantum mechanics we have mainly been concerned with its predictions from the perspective of an external observer. This is in strong contrast to the theory of general relativity, where the physics is governed by the intrinsic properties of space-time. At the same time, the precise relation between space-time and quantum mechanics is still one of the greatest problems of theoretical physics. This immediately raises the question on the completeness of our understanding of quantum mechanics. Here we address the problem by making an intrinsic analysis of observables in generic quantum systems. We show that there is an extreme fine tuning problem for the emergence of physics from the Hilbert space dynamics. However, for any initial condition and Hamiltonian, there exists a special set of observables. We show that these observables are intimately linked to the natural configuration space in which an area law for the entanglement is inevitable. We argue that this implies emergent gravity.

Unfolding Reality: A Conceptual Framework for the Emergence of Spacetime from a Pre-Classical Domain

Jing Pan

This paper proposes a conceptual framework in which classical spacetime is not fundamental but emerges from a deeper, timeless, pre-geometric domain. I refer to these two layers as Ubigger, a pre-classical domain without space, time, separability, or numerical structure, and Uclassical, the emergent layer in which classical physics operates. The transition between them occurs through an unfolding process that generates spatial extension, temporal ordering, dimensional structure, and causal relations. Within this framework, quantum superposition and entanglement reflect pre-classical unity rather than nonlocal influence, while measurement corresponds to unfolding into definite classical configurations. The same unfolding mechanism provides intuitive reinterpretations of several longstanding conceptual challenges, including the Big Bang, cosmic expansion, gravitational curvature, the measurement problem, as well as the arrow of time and the universe’s low-entropy origin.
