ABSTRACT: In spite of their speculative nature, traversable wormholes are a topic of interest that started with the Einstein-Rosen bridge in 1935 and became a major research area with the introduction of the Morris-Thorne wormhole in 1988. It also became apparent in time that such wormholes are likely to be compact stellar objects, akin to neutron stars. Although widely discussed, wormholes having a low energy density may therefore not be massive enough to exist on a macroscopic scale. Important examples are wormholes based on a noncommutative geometry background and wormholes supported by the negative energy density sourced by the Casimir effect. The main goal of this paper is to invoke

modified gravity to provide the extra degrees of freedom to help overcome these obstacles.
