We review recent work on wormhole geometries in the context of modified theories of gravity, Outdoor Counter Barstool in particular, in f(R) gravity and with a nonminimal curvature-matter coupling, and in the recently proposed hybrid metric-Palatini theory.In principle, the normal matter threading the throat can be shown to satisfy the energy conditions and it is the higher order curvatures terms that sustain these wormhole geometries.We also briefly review the conversion Faber Galileo duct out induction hob 340.0540.965 A+++ 4 hob of wormholes into time-machines, explore several of the time travel paradoxes and possible remedies to these intriguing side-effects in wormhole physics.
