Wormholes, the weak energy condition, and scalar-tensor gravity
Wormholes, the weak energy condition, and scalar-tensor gravity
We obtain a large class of Lorentzian wormhole spacetimes in scalar-tensor gravity, for which the matter stress energy does satisfy the weak energy condition. Our constructions have zero Ricci scalar and an everywhere finite, non-zero scalar field profile. Interpreting the scalar-tensor gravity as an effective on-brane theory resulting from a …
