Nmax

Abstract The Grude Nmax Hypothesis proposes a spin-0 scalar field, Nmax, with mass about 1.78 × 10^-17 eV and full Compton wavelength λ = h / (m c) ≈ 0.465 AU, as a counterbalance to the Higgs field. In this toy framework the two fields form a complementary pair: the Higgs field generates particle masses, while Nmax is introduced to limit spacetime curvature. The hypothesis is motivated by a wave-interference analogy from radio physics. If realized, Nmax would prevent curvature singularities, allow non-singular black-hole cores, and may stabilize wormhole throats without an independent exotic-matter source. Neutrinos are produced through a phenomenological Higgs–Nmax interaction in regions of high curvature. The model is parameterized by a modified Einstein equation with an effective cosmological term Λ_Nmax proportional to N_VEV squared, and by a simple Lagrangian that couples N to curvature, electromagnetism, the energy-momentum tensor and neutrinos. The proposal is speculative and is offered as a target for falsification. Possible signatures include gravitational-wave ringdown anomalies (LISA, Taiji), lensing deviations (Event Horizon Telescope), neutrino-burst or oscillation anomalies (IceCube, DUNE, Super-Kamiokande), and large-scale CMB imprints
