FINDING: Tabletop experiments for quantum gravity are now feasible using matter-wave interferometry and optomechanical systems, potentially enabling direct observation of quantum gravitational effects at low energies. | MATH: Key constants: Planck length \ (lP = G/c³ 1. 616 10^-35 \, m \) ; Planck mass \ (mP = c/G 2. 176 10^-8 \, kg \) ; Newton's constant \ (G 6. 674 10^-11 \, m³ kg^-1 s^-2 \). The experiment probes the quantum superposition of masses, with phase shift \ (G m₁ m₂ t³ / d³\) (the "T-cubed" scaling from Penrose–Folman). | CONNECTION: The T-cubed scaling involves a cubic time dependence, which resonates with cubic lattice symmetries (e. g. , simple cubic, body-centered cubic) common in crystallography. The ratio of Planck length to typical experimental scales (\ (10^-10 \, m\) ) is \ (1. 6 10^-25\), far from g Author: Andrew Stewart Caldin, Independent Researcher, UK.
