It is shown that, (a Λ2 + b |H|2)R in a spacetime of curvature R is a natural ultraviolet (U V) completion of (a Λ4 + b Λ2 |H|2) in the flat-spacetime Standard Model (S M) with Higgs field H, U V scale Λ and loop factors a, b. This curvature completion rests on the fact that a Λ-mass gauge theory in flat spacetime turns, on the cut-view R = 4 Λ2, into a massless gauge theory in curved spacetime. It provides a symmetry reason for curved spacetime, wherein gravity and matter are both low-energy effective phenomena. Gravity arises correctly if new physics exists with at least 63 more bosons than fermions, with no need to interact with the S M and with dark matter as a natural harbinger. It can source various cosmological, astrophysical and collider phenomena depending on its spectrum and couplings to the S M.
