Threads of Spacetime: A Unified Framework for Quantum Fields, Gravity, and Decoherence Rajdeep Singh Lather November 2025 Abstract I propose a conceptual framework in which spacetime consists of fundamental one-dimensional “threads” stitched together at the quantum scale. Vibrational modes along these threads produce quantum fields, while collective distortions of the network reproduce gravitational dynamics. Quantum decoherence arises naturally from interactions between localized excitations and the surrounding thread fabric. Apparent faster-than-light quantum correlations occur via local thread dynamics, while the cosmological speed limit emerges from the stitching structure of the network. Unlike string theory, this model does not require additional spatial dimensions. In flat, unstretched regions, the theory reproduces standard quantum field theory, while deviations in curved spacetime suggest possible experimental tests. Keywords: quantum gravity, quantum fields, spacetime threads, decoherence, entanglement, Standard Model 1 Introduction Quantum mechanics and general relativity remain conceptually separate in modern physics. Quantum fields describe particles, while general relativity describes gravity as curvature of spacetime. Unifying them is a core challenge. This paper presents a conceptual model: spacetime is a discrete network of onedimensional threads. Vibrational excitations along these threads correspond to quantum fields, and collective distortions correspond to gravitational phenomena. This framework allows intuitive accounts of mass, decoherence, quantum correlations, and entanglement, while remaining compatible with classical relativity at large scales. Unlike string theory, this approach does not require additional spatial dimensions. 2 Fundamental Structure: The Thread Network •Threads: Spacetime is composed of discrete, one-dimensional threads stitched together on the quantum scale. •Stitching / Binding: Threads form a coherent lattice-like network. The stitching controls how excitations propagate, establishing the cosmological speed limit. 1
•Continuum Limit: At scales much larger than the stitching scale, the network approximates a smooth manifold consistent with general relativity. Local excitations along threads can propagate more freely than classical spacetime suggests, while the stitched network enforces macroscopic causal constraints. 3 Quantum Fields as Vibrational Modes •Vibrational Modes: Particles correspond to quantized vibrations along threads, with different modes representing distinct particle species. •Mass: Inertia arises from interactions between vibrational energy and the thread network. Stronger or higher-frequency vibrations couple more with the network. •Charge & Spin: Internal symmetries of vibrational patterns encode quantum numbers like charge and spin. •Massless Modes: Some weakly coupled modes behave effectively massless, such as photons. In flat, unstretched regions, these dynamics reproduce standard quantum field theory, ensuring consistency with existing experiments. 4 Gravity and Network Dynamics •Curvature: Large-scale distortions of the thread network reproduce spacetime curvature. •Gravitational Waves: Propagating deformations in the network correspond to gravitational waves. •Energy–Mass Coupling: Energy stored in vibrations contributes to curvature, paralleling the stress-energy tensor in general relativity. Gravity emerges deterministically from the same substrate that gives rise to quantum fields, avoiding arbitrary stochastic elements. 5 Decoherence via Thread Interactions Decoherence naturally arises from this framework: 1. A quantum particle is a localized vibrational excitation. 2. It interacts with neighboring threads, distributing its vibrational energy. 3. Phase information leaks into the broader network, suppressing interference and producing classical behavior. This provides a concrete, physical mechanism for the quantum-to-classical transition. 2
6 Quantum Correlations and Apparent Superluminality Entanglement correlations appear instantaneous, yet no usable information travels faster than light. In the thread model: •Local excitations can propagate at high “internal” speeds along individual threads. •To influence the macroscopic stitched network, interactions must obey the causal constraints of stitching. •Consequently, entanglement leverages local thread dynamics while classical signalling remains causal. This separates microscopic freedom from macroscopic causality, reconciling quantum nonlocality with relativity. 7 Advantages of the Model •Unified substrate for matter and spacetime. •Intuitive understanding of mass as an interaction with the network. •Physical basis for decoherence. •Deterministic gravity emerging from structured vibrations. •No extra dimensions required. •Experimental accessibility: reproduces QFT in flat regions, predicts deviations in curved regions. •Emergent relativistic symmetries at large scales. 8 Challenges and Open Questions •Mapping vibrational modes to Standard Model particles and interactions. •Demonstrating approximate Lorentz invariance from a discrete network. •Dynamically deriving the stitching scale rather than postulating it. •Identifying experimental signatures in propagation, decoherence, or gravitational effects. •Developing a consistent mathematical description of thread dynamics. 3
9 Conclusion The “Threads of Spacetime” model offers a physically grounded, unified framework connecting quantum fields, gravity, decoherence, and entanglement. Spacetime emerges from one-dimensional threads whose vibrations produce particles and whose distortions produce geometry. The absence of extra dimensions is a key strength, and exact recovery of standard QFT in flat space ensures consistency. Deviations in curved spacetime offer avenues for experimental investigation. Further work is required to formalize the model and derive predictive results. License This work is licensed under a Creative Commons Attribution 4.0 International License (CC BY 4.0).
