Cosmic acceleration from first principles
  General relativistic entropic acceleration theory may explain the present
cosmic acceleration from first principles without the need of introducing a
cosmological constant. Following the covariant formulation of non-equilibrium
phenomena in the context of a homogeneous and isotropic
Friedmann-Lemaitre-Robertson-Walker (FLRW) metric, we find that the growth of
entropy associated with the causal horizon of our universe (inside a finite
bubble in eternal inflation) induces an acceleration that is essentially
indistinguishable from that of $\Lambda$CDM, except for a slightly larger
present rate of expansion compared to what would be expected from the CMB in
$\Lambda$CDM, possibly solving the so-called $H_0$ tension. The matter content
of the universe is unchanged and the coincidence problem is resolved since it
is the growth of the causal horizon of matter that introduces this new
relativistic entropic force. The cosmological constant is made unnecessary and
the future hypersurface is Minkowsky rather than de Sitter.
