Scientific paper

In this Letter we consider three future singularities in different
Friedmann-Lema\^{\i}tre-Robertson-Walker scenarios and show that the universe
departs more and more from thermodynamic equilibrium as the corresponding
singularity is approached. Though not proven in general, this feature may
characterize future singularities of homogeneous and isotropic cosmologies.
