Problems of Massive Gravities
S. Deser, K. Izumi, Y. C. Ong +1
The method of characteristics is a key tool for studying consistency of equations of motion; it allows issues such as predictability, maximal propagation speed, superluminality, un…

Superluminal Propagation and Acausality of Nonlinear Massive Gravity
S. Deser, K. Izumi, Y. C. Ong +1
Massive gravity is an old idea: trading geometry for mass. Much effort has been expended on establishing a healthy model, culminating in the current ghost-free version. We summariz…

Massive Gravity Acausality Redux
S. Deser, K. Izumi, Y. C. Ong +1
Massive gravity (mGR) is a 5(=2s+1) degree of freedom, finite range extension of GR. However, amongst other problems, it is plagued by superluminal propagation, first uncovered via…
