1ST SOLUTION. “The approach developed in [1] implies that, at the ultra-fast and microscopic (Planck) scales, the “true” magnitude of the cosmological constant is very large, and its magnitude is defined by the vacuum energy density predicted by quantum mechanics, which is about 120 orders of magnitude larger than the value experimentally observed at cosmological scales.”
