Unveiling the Massless Graviton from Lattice Fluctuations: Finite-Size Scaling Evidence in the QGEFT Vacuum

The spin-2 fluctuation mass gap is shown to be a finite-volume kinematic artifact rather than an intrinsic field property. Under the Finite-Size Scaling behavior of $m_g(1/L)$ across sizes $N \in \{256, 512, 1024, 2048\}$, the mass gap extrapolates to a physical infinite-volume value of $m_0 \approx 0.0003 \pm 0.0006 \approx 0$ with $R^2 \approx 0.999$, proving that clean, massless spin-2 excitations propagate freely across the emergent vacuum.

Abstract

The spin-2 fluctuation mass gap is shown to be a finite-volume kinematic artifact rather than an intrinsic field property. Under the Finite-Size Scaling behavior of $m_g(1/L)$ across sizes $N \in \{256, 512, 1024, 2048\}$, the mass gap extrapolates to a physical infinite-volume value of $m_0 \approx 0.0003 \pm 0.0006 \approx 0$ with $R^2 \approx 0.999$, proving that clean, massless spin-2 excitations propagate freely across the emergent vacuum.
