Description
The major concern in any modified theory of gravity is about its
consistency. The absence of ghosts in bimetric theory is ensured by the
special form of the interaction term that is based on the matrix square
root function of the two metric fields combined. In this talk we present
the theorem which connects this square root also with the local
causality and highlight its role in empowering the field dynamics of the
theory to be predictive.
