Query: Big-Rip, Sudden Future, and other exotic singularities in the universe   We discuss exotic singularities in the evolution of the universe motivated by
the progress of observations in cosmology. Among them there are: Big-Rip (BR),
Sudden Future Singularities (SFS), Generalized Sudden Future Singularities
(GSFS), Finite Density Singularities (FD), type III, and type IV singularities.
We relate some of these singularities with higher-order characteristics of
expansion such as jerk and snap. We also discuss the behaviour of pointlike
objects and classical strings on the approach to these singularities.
