How light is gravity?
aLIGO recent detections of gravitational waves represent a direct manifestation of the propagating degrees of freedom of gravity. While these detections have been successfully used to examine the basic properties of these gravitational degrees of freedom and sets an upper bound on its mass, I will explore the possibility for this mass to be sufficiently small to pass current tests of gravity and yet sufficiently large to have deep potential implications on our observable Universe.
