### Fluctuations of Newton's Constant in Sub-millimeter Scales as Evidence for TGD

#### Abstract

Washington group has reported evidence for the variation of the effective value of Newton's constant in sub-millimeter scales. The proposed interpretation in terms of spatially oscillating variation of the effective value of *G* does not look convincing. In this article the interpretation as fluctuations in the value of *G* predicted by TGD is discussed. The fluctuations are predicted to be make themselves visible in p-adic lengths scales assignable to the density of vacuum energy. The correspondence between these relatively short p-adic length scales and the hierarchy of cosmological p-adic length scales defined by length scale dependent cosmological constant *Λ *suggests that gravitational physics at short and long length scales reflect each other. Biologically interesting p-adic length scales would be of special interest quantum gravitationally.
