  Modified dark matter (MDM, formerly known as MoNDian dark matter) is a
phenomenological model of dark matter, inspired by quantum gravity. We review
the construction of MDM by generalizing entropic gravity to de-Sitter space as
is appropriate for an accelerating universe (in accordance with the Lambda-CDM
model). Unlike cold dark matter models, the MDM mass profile depends on the
baryonic mass. We successfully fit the rotation curves to a sample of 30 local
spiral galaxies with a single free parameter (viz., the mass-to-light ratio for
each galaxy). We show that dynamical and observed masses agree in a sample of
93 galactic clusters. We also comment on strong gravitational lensing in the
context of MDM.
