ABSTRACT: Within the thermodynamic model of gravity the dark energy is identified
with the energy of collective gravitational interactions of all particles in
the universe, which is missing in the standard treatments. For the
model-universe we estimate the radiation, baryon and dark energy densities and
obtain the values which are close to the current observations. It is shown that
total gravitational potential of a particle from the world ensemble is a scale-dependent
quantity and its value is twice Newtonian potential. The
Einstein-Infeld-Hoffmann approximation to general relativity was used to show
that the acceleration of a particle from the world ensemble can be considered
as a relative quantity when the universe is described by the flat cosmological
model.
