Query: Entropic theory of Gravitation   We construct a manifestly Machian theory of gravitation on the foundation
that information in the universe cannot be destroyed (Landauer's principle). If
no bit of information in the Universe is lost, than the sum of the entropies of
the geometric and the matter fields should be conserved. We propose a local
invariant expression for the entropy of the geometric field and formulate a
variational principle on the entropic functional which produces entropic field
equations. This information-theoretic approach implies that the geometric field
does not exist in an empty of matter Universe, the material entropy is geometry
dependent, matter can exchange information (entropy) with the geometric field
and a quantum condensate can channel energy into the geometric field at a
particular coherent state. The entropic field equations feature a non-intuitive
direct coupling between the material fields and the geometric field, which acts
as an entropy reservoir. Cosmological consequences such as the emergence of the
cosmological constant as well as experimental consequences involving
gravity-quantum condensate interaction are discussed. The energetic aspect of
the theory restores the repertoire of the classical General Relativity up to a
different coupling constant between the fields.
