Query: Do recent observations favor a cosmological event horizon: A
  thermodynamical prescription?   Recent observational evidences claim an accelerating expansion of the
universe at present epoch. It is commonly incorporated in standard cosmology by
the introduction of an exotic matter (that violates the strong energy
condition) known as dark energy (DE). As event horizon exists for accelerating
universe so there has been a lot of work on universal thermodynamics (i.e.,
thermodynamics of the universe bounded by apparent or event horizon). Recently,
thermodynamical equilibrium has been examined for both the horizons. In the
present work we show that universal thermodynamics with event horizon is
favored by DE from the point of view of equilibrium thermodynamical
prescription.
