CMBR anisotropy in the framework of cosmological extrapolation of MOND

A modified gravity involving a critical acceleration, as empirically established at galactic scales and successfully tested by data on supernovae of type Ia, can fit the measured multipole spectrum of anisotropy in the cosmic microwave background radiation, so that a dark sector of Universe is constructively mimicked as caused by the dynamics beyond the general relativity. Physical consequences, verifiable predictions and falsifiable issues are listed and discussed.
