DESCRIPTION:Extensions to General Relativity abound in the literature. How
 ever\, rigorous testing of these theories against observational data is ti
 me-consuming\, and in a very disjointed state. This leads us to seek an ef
 ficient\, general way to test gravity which is independent of the specific
 s of individual theories.\n\nI will present two strands of work related to
  this gravitationally agnostic approach. First\, I will introduce a system
  for unifying tests of gravity on all scales in the universe\, from labora
 tory experiments to cosmology. This hints at an untested regime of gravita
 tional fields which deserves further investigation.\n\nSecondly\, I will s
 how how a parameterisation of alternative gravity theories — written dow
 n at the level of the field equations — propagates through to `real-worl
 d’ effects on cosmological observables. Turning this around\, I will ind
 icate the strength of model-independent constraints on gravity we can expe
 ct in the near future.
