Query: On entropic gravity: the entropy postulate, entropy content of screens
  and relation to quantum mechanics   We consider the controversial hypothesis that gravity is an entropic force
that has its origin in the thermodynamics of holographic screens. Several key
aspects of entropic gravity are discussed. In particular, we revisit and
elaborate on our criticism of the recent claim that entropic gravity fails to
explain observations involving gravitationally-bound quantum states of neutrons
in the GRANIT experiment and gravitationally induced quantum interference. We
argue that the analysis leading to this claim is troubled by a
misinterpretation concerning the relation between the microstates of a
holographic screen and the state of a particle in the emergent space,
engendering inconsistencies. A point of view that could resolve the
inconsistencies is presented. We expound the general idea of the aforementioned
critical analysis of entropic gravity in such a consistent setting. This
enables us to clarify the problem and to identify a premise whose validity will
decide the faith of the criticism against entropic gravity. It is argued that
in order to reach a sensible conclusion we need more detailed knowledge on
entropic gravity. These arguments are relevant to any theory of emergent space,
where the entropy of the microscopic system depends on the distribution of
matter in the emergent space.
