Phantom fluid supporting traversable wormholes in alternative gravity with extra material terms

Understand

Wormholes are tunnels connecting different regions in space-time.

• They were obtained originally as a solution for Einstein's General Relativity theory and according to this theory they need to be filled by an exotic kind of anisotropic matter.
• In the present sense, by "exotic matter" we mean matter that does not satisfy the energy conditions.
• In this article we propose the modelling of wormholes within an alternative gravity theory that proposes an extra material (rather than geometrical) term in its gravitational action.
