A first-principles perturbative framework is developed to constrain the Moon's elastic parameters and density structure from seismic responses to calibrated gravitational waves, claiming an order-of-magnitude error reduction.

Optimal placement of two stations in an isotropic Gaussian seismic field reduces equivalent seismic noise ASD by a factor of ~2.3 at 0.3 Hz versus a single station, producing oscillatory features from Bessel-function correlations.
High-resolution lunar simulations reveal up to tenfold amplification of deci-hertz gravitational-wave signals in thick-crust regions via mode coupling.
Lunar GW observatories can deliver weeks-to-months early warnings, 0.01 deg² localizations, and ~100 well-localized BNS events per year for GW170817-like sources, with multi-band networks yielding 0.1% mass-ratio and 1% distance precision.
LGWA could observe more than one third of known binary black hole events, detect ~90 mergers per year, and measure chirp mass better than third-generation detectors for massive systems.
Next-generation GW detector networks can constrain the spatial curvature parameter Ω_k to 1σ uncertainty of 0.029 using intermediate-mass binary black hole bright sirens.
Multiple viable sites on the Moon satisfy isolation, protection, accessibility, and line-of-sight constraints for both LILA-Pioneer and LILA-Horizon gravitational wave detectors.
The paper reviews cosmological tensions including the H0 and S8 discrepancies and explores new physics models that could explain them.
