Cosmology with the Ly-a forest

Abstract

The Lya forest has emerged as one of the few systems capable of probing small-scale structure at high-z with high precision. In this talk I highlight two areas in which the Lya forest is shedding light on fundamental questions in cosmology, one speculative and one which should be possible in the near future.
