Cosmological constant problem remains open

Establish a resolution to the cosmological constant problem by reconciling the quantum field theory prediction of the vacuum energy (e.g., Λ_QFT ≈ 10^−6 m^−2) with the observed cosmological constant Λ_obs = 1.088(30) × 10^−52 m^−2, thereby explaining the 46‑order discrepancy between theory and observation.

Background

The paper reviews the long-standing discrepancy between the quantum field theory estimate of the cosmological constant and its observed value, noting the 46 orders of magnitude difference emphasized since Zeldovich’s work. While the author discusses a vacuum mechanics approach and provides a theoretical value consistent with observations, the general problem of explaining why quantum field contributions do not inflate Λ to the much larger QFT value remains unresolved in the broader literature.
