SUMMARY:Positivity in the Sky - Professor Claudia de Rham - Imperial Colle
 ge\, London

CONTACT:Amanda Stagg
DESCRIPTION:I will discuss the subtle interplay between the behaviour of g
 ravity as we observe it in our “everyday experiments”\, and its embedd
 ing within an ultimate high energy completion. In particular\, I will emph
 asize how the notion of causality is manifested with gravity\, a considera
 tion which is particularly relevant for putting constraints on the physica
 l theories we use to describe observations and make future predictions. By
  considering low-energy processes including effects from Standard Model pa
 rticles\, I will also argue how we can get an insight on some properties o
 f physics at high energy\, well beyond what is accessible with current and
  future observations and experiments.
