Massive Gravity Theories  

In General blue bullet s.a. gravity theories.
* Idea: A type of modification of general relativity in which gravitons have mass.
* History: The first linearized massive gravity theory was the Pauli-Fierz theory, which included a simple, quadratic mass term and is not considered viable because it has a ghost mode in its spectrum, with the resultant loss of unitarity of the quantum theory; Non-Pauli-Fierz theories with a generic graviton mass term and/or higher-order terms have more recently been proposed, including the dRGT non-linear massive gravity theory; 2015, Considered to be a hot topic in theoretical physics.
* Rem: Giving mass to the graviton is not as straightforward as in the case of a scalar field, since it requires the introduction of a second, fiducial metric; This modification changes the theory drastically, for example adding degrees of freedom that may alter its phenomenology and viability.
