Sudden Future Singularity models as an alternative to Dark Energy?
  Current observational evidence does not yet exclude the possibility that dark
energy could be in the form of phantom energy. A universe consisting of a
phantom constituent will be driven toward a drastic end known as the `Big Rip'
singularity where all the matter in the universe will be destroyed. Motivated
by this possibility, other evolutionary scenarios have been explored by Barrow,
including the phenomena which he called Sudden Future Singularities (SFS). In
such a model it is possible to have a blow up of the pressure occurring at
sometime in the future evolution of the universe while the energy density would
remain unaffected. The particular evolution of the scale factor of the universe
in this model that results in a singular behaviour of the pressure also admits
acceleration in the current era. In this paper we will present the results of
our confrontation of one example class of SFS models with the available
cosmological data from high redshift supernovae, baryon acoustic oscillations
(BAO) and the cosmic microwave background (CMB). We then discuss the viability
of the model in question as an alternative to dark energy.
