Abstract

The redshifts of all cosmologically distant sources are expected to experience a small, systematic drift as a function of time due to the evolution of the Universe's expansion rate. Here, we briefly review the motivation for measuring this effect and summarise our reasons for believing that the E-ELT will be the first telescope to detect it.
