Query: G\"{o}del-type Solutions in Cubic Galileon Gravity   We address the homogeneous in space and time (ST-homogeneous) G\"{o}del-type
metrics within the cubic galileon theory, a particular class of generalized
galileon theories. We check the consistency of such spacetimes for a physically
well-motivated matter content, namely, a perfect fluid and an electromagnetic
field. In this scenario, we find that the admissible solutions impose
constraints on the constant couplings ($c_{i}$'s) of the cubic galileon theory
to ensure the consistency. Also, we show the existence of a vacuum completely
causal solution.
