Weak Singularities in Cosmology

It is well known that our universe contains a singularity in the past and that it can develop a singularity to the future. The best know example of this is called the Big Crunch, but recent years have shown that a wide variety of exotic future singularities can also exist, many of which are of a very weak nature. I review these results and describe recent work which demonstrates that these weak singularities generically form in a universe containing a scalar field with a power-law potential. Extensions and implications are discussed.
