on to gravitational physics. By carefuly measuring the morphology and growth
of structure in the Universe it may be possible to constrain general relativity on a
completely new range of scales. It also allows us to explore a plethora of modified
gravity theories that have emerged as an attempt to explain the observational
evidence for dark energy. I will discuss the challenges and approaches which
are being taken in this new field.
