Revisiting wormhole energy conditions in Riemann-Cartan spacetimes and under Weyl transformations
Fayçal Hammad, Étienne Massé, Patrick Labelle
We show that the violation of the null energy condition by matter, required by traversable wormholes, can be removed in spacetimes with torsion. In addition, we show that this viol…
