  Detailed observations of the temperature fluctuations in the microwave
background radiation indicate that we live in an open universe. From the size
of these fluctuations it is concluded that the geometry of the universe is
quite close to Euclidean. In terms Friedmann models, this implies a mass
density within 10% of the critical density required for a flat universe.
Observed mass can only account for 30% of this mass density. Recently, an
outstanding observation revealed that cosmos is accelerating. This motivated
some astronomers to explain the missing 70% as some exotic dark energy called
quintessence. In this essay, we present an alternative explanation to these
cosmological issues in terms of the Friedmann Thermodynamics. This model has
the capability of making definite predictions about the geometry of the
universe, the missing mass problem, and the acceleration of the universe
in-line with the recent observations. For future observations, we also predict
where this model will start differing from the quintessence models.
