Study on the Inversion of Graviton Scale Interval Based on Gravitational Wave Observation and Quantum Gravitational Boundary

Abstract Quantum gravity research has long faced a core deficiency. As the microscopic carrier of gravitational interaction, the graviton lacks scale and boundary parameters constrained by experimental observations, leaving existing gravitational models confined to qualitative assumptions and unable to support systematic quantitative deduction. Based on the latest gravitational wave dispersion observation data from the LIGO‑Virgo collaboration and the Planck‑scale boundary of quantum gravity, this paper adopts a dual‑constraint inversion method to strictly define the lower limit of the microscopic scale and the upper limit of the macroscopic coherence scale of gravitons, and establishes a physically self‑consistent and observation‑compatible complete scale interval. The findings resolve the longstanding bottleneck of missing quantitative anchors for microscopic gravitational media, provide accurate quantitative support for fluidized gravitational field models, spatial medium dynamics, and cosmic macroscopic force mechanism research, and realize a critical leap from qualitative hypotheses to calculable and verifiable theoretical systems. 摘要 当前量子引力研究长期存在核心短板:引力子作为引力相互作用的微观载体,始终缺乏可被实验观测约束的尺度与边界参数,导致各类引力模型仅能停留在定性假设,无法完成体系化定量推演。本文依托LIGO-Virgo最新引力波色散观测数据、普朗克尺度量子引力极限边界,采用双向约束反推方法,严格界定引力子微观尺度下限与宏观相干尺度上限,给出物理自洽、观测兼容的引力子完整尺度区间。本文研究结论解决了长期以来微观引力介质无量化锚点的行业痛点,可为流体化引力场模型、空间介质动力学、宇宙宏观作用力机制研究提供精准定量基础,实现从定性假说到可计算、可校验理论体系的关键跨越。
