摘要：
In this paper, we study Godel universe in the framework of f(R, T) modified theories of gravity, where R is the curvature scalar and T the trace of the energy-momentum tensor. We demonstrate that Godel solution occurs in this modified theory and still we suggest a path to understanding the smallness of the cosmological constant.
