Phys. Rev. D 65, 087303 (2002) [4 pages]Holography and the large number hypothesisReceived 12 September 2001; published 8 April 2002 Dirac’s large number hypothesis is motivated by certain scaling transformations that relate the parameters of macro and microphysics. We show that these relations can actually be explained in terms of the holographic N bound conjectured by Bousso and a series of purely cosmological observations, namely, that our universe is spatially homogeneous, isotropic, and flat to a high degree of approximation and that the cosmological constant dominates the energy density at present. © 2002 The American Physical Society URL:
